hi
Normally the production support activities include
Scheduling
R/3 Job Monitoring
B/W Job Monitoring
Taking corrective action for failed data loads.
Working on some tickets with small changes in reports or in AWB objects.
The activities in a typical Production Support would be as follows:
1. Data Loading - could be using process chains or manual loads.
2. Resolving urgent user issues - helpline activities
3. Modifying BW reports as per the need of the user.
4. Creating aggregates in Prod system
5. Regression testing when version/patch upgrade is done.
6. Creating adhoc hierarchies.
we can perform the daily activities in Production
1. Monitoring Data load failures thru RSMO
2. Monitoring Process Chains Daily/weekly/monthly
3. Perform Change run Hierarchy
4. Check Aggr's Rollup
To add to the above
1)check data targets are ready for reporting,
2) No failed or cancelled jobs in sm37 monitors and Bw Monitor.
3) All requests are loaded for day, monthly and yearly also.
4) Also to note down time taken for loading of critical info cubes which are used for reporting.
5) Is there any break in any schedules from your process chains.
As the frequent failures and errors , there is no fixed reason for the load to be fail , if you want it for the interview perspective I would answer it in this way.
a) Loads can be failed due to the invalid characters
b) Can be because of the deadlock in the system
c) Can be because of previous load failure , if the load is dependant on other loads
d) Can be because of erroneous records
e) Can be because of RFC connections
These are some of the reasons for the load failures.
Why there is frequent load failures during extractions? and how to analyse them?
If these failures are related to Data, there might be data inconsistency in source system. Though we are handling properly in transfer rules. We can monitor these issues in T-code -> RSMO and PSA (failed records) and update.
If we are talking about whole extraction process, there might be issues of work process scheduling and IDoc transfer to target system from source system. These issues can be re-initiated by canceling that specific data load and ( usually by changing Request color from Yellow - > Red in RSMO). and restart the extraction.
What is the daily task we do in production support.How many times we will extract the data at what times.
It depends... Data load timings are in the range of 30 mins to 8 hrs. This time is depends in number of records and kind of transfer rules you have provided. If transfer rules have some kind of round about transfer rules and updates rules has calculations for customized key figures... long times are expected..
Usually You need to work on RSMO and see what records are failing.. and update from PSA.
What are some of the frequent failures and errors?
As the frequent failures and errors , there is no fixed reason for the load to be fail , if you want it for the interview perspective I would answer it in this way.
a) Loads can be failed due to the invalid characters
b) Can be because of the deadlock in the system
c) Can be because of previous load failure , if the load is dependant on other loads
d) Can be because of erroneous records
e) Can be because of RFC connections
These are some of the reasons for the load failures.
for Rfc connections:
We use SM59 for creating RFC destinations
assign points if useful

Sap-abap expected topics in interview
Hi ,
Iam trying for job in sap as a 2+ years of experience.
what r the the different topics can i expect in interview ?
What are the imp topics as a 2+ experience.
Pls help me.
I think it may help many people.
regards,
kala.Hi
1. How data is stored in cluster table?
Each field of cluster table behaves as tables which contains the no. of entries.
2. What are client dependant objects in abap/sap?
SAP Script layout, text element, and some DDIC objects.
3. On which even we can validate the input fields in module progams?
In PAI (Write field statement on field you want to validate, if you want to validate group of fields put in chain and End chain statement.)
4. In selection screen I have three fields, plant mat no and material group. If I input plant how do I get the mat no and material group based on plant dynamically?
AT SELECTION-SCREEN ON VALUE-REQUEST FOR MATERIAL.
CALL FUNCTION 'F4IF_INT_TABLE_VALUE_REQUEST' to get material and material group for the plant.
5. How do you get output from IDOC?
Data in IDOc is stored in segments, the output from Idoc is obtained by reading the data stored in its respective segments.
6. When top of the page event is triggered?
After excuteing first write statement in start-of-selection event.
7. Can we create field without data element and how?
In SE11 one option is available above the fields strip. Data element/ direct type.
8. How do we debug sapscript?
Go to SE71 give lay set name , go to utilities select debugger mode on.
9. Which transaction code can I used to analyze the performance of ABAP program.
TCode AL21.
10. How can I copy a standard table to make my own z_table.
Go to transaction SE11. Then there is one option to copy table. Press that button. Enter the name of the standard table and in the Target table enter Z table name and press enter.
Following are some of the answers which I gave upto my knowledge.
1. What is the use of 'outerjoin'
Ans. With the use of outer join you can join the tables even there is no entry in all the tables used in the view.
In case of inner join there should be an entry in al the tables use in the view.
2. When to use logical database?
Ans. Advantage of Logical databases:
less coding s required to retrieve data compared to normal internel tables.
Tables used LDB are in hierarchial structure.
3. What is the use of 'table index'?
Ans .Index is used for faster access of data base tables.
4. What is the use of 'FOR ALL ENTRIES'?
Ans. To avoid nested select statements we use SELECT FOR ALL ENTRIES statement.
If there r more than 10000 records SELECT FOR ALL ENTRIES is used.
Performance wise SELECT FOR ALL ENTRIES is better to use.
5. Can you set up background processing using CALL TRANSACTION?
Yes,Using No Screen Mode.
6. What are table buffers?
Table buffers reside locally on each application server in the system. The data of buffered tables can thus be accessed
directly from the buffer of the application server. This avoids the time-consuming process of accessing the database.
Buffering is useful if table needs to be accessed more no. of times in a program.

Deepti
1. There are other ways of entering data into a DB table. ex. B D C
2. Collect statement collect/adds the records basing on a key field. allows to create summarised data sets.
Append will append/add a record at the end of existing records
8. to release an object - use se10/se9
9. sales doc flow: S. A. - S. O. - Delivery - Billing
12. Delivery - invoice.
15. field symbols are used for dynamic allocation. at runtime u can assign a concrete field to field-symbol.
Kishore
1. you can go to abap editor (se38) and use insert statement for insertion update for update and modify for modifications.
2. collect will not allow duplicate entries, while append can allow duplicates.
3. if any changes are made to objects they are to be transported to different systems i.e, change and transport.
4. in user exits we go by general method for enhancements while BADIs we use objects (oops concepts)
methods for enhancement.
14. table controls are enhanced version for step loops where we can expand rows .main difference between these two
is step loop can be expanded to two lines table controls can`t.
15. field symbols are just like pointers concept which are used in C language. We use them when we want to refer to
the fields considered,it doesnt allocate any memory for it.
Venu Rapolu
1. Ans: Using BDC., LSMW,,ALE., BAPI
2. Ans: Collect: it adds the numeric fields to the existing non numeric key field records., thereby avoiding duplicate
values., and append will simply adds the record
3 . Ans: The CTS contains work bench organizer and transport system :
The workbench organizer is used to record and contol changes to the ABAP/4 development objects;
The transport system is used to move objects from an SAP dev.system to production system
6. Ans: Outbound interface is used to send IDocs to the ALE server.,
Inbound interface is used to Analyse the received Idoc.
7. Ans: We (ABAPers) don't do.
8. Ans: se09 or se10
13. Ans: MATMAS
CREMAS
DEBMAS
GLMAST etc...
14. Ans: to display records in table format., we use in Screens
15. Ans: we assign the field content at run time with ASSIGN stmt.
Satish D
1. goto se16 u can view the table contents
2. collect will collects all the numeric fields of nonnumeric field values
append will append record at the end of table
3. when we are creatiing new task like dev. a new prg.. after completion of dev. that will be trnsported to testing system or production system to do that we are assigning an
transport request from our dev.class(system) by using se09
4. badis are dev. by class and inheritence methods where as user exitsdev by SAP only and empty shells filled wit user logic
5. go to system then status
6. outbound generating an idoc in ale layer with master_idoc_create_messgetype,
inbound is receivng system with idoc_inbound_process, gives an return variable wether it is sucess or not
7. no we have to configur that
8. go to se09 or se01 there write your task no and use release button it will asks whats the other system name
and number enter them and relase by pressing jeep button
9. inquiry
quotation
sales order
shipping
delivery
invoice
return goods
12. after creation of delivry note invoice is prepared
13. master_idoc_distribute will generate standard idoc
Deepti
I am enclosing some of answers which I know.
1. We can use t.Code SE16 to enter values into table only if table maintainence is allowed for that table.
2. Append will add new entries into the table where as collect add into the numeric type fields if other charatcer fields
matches to your selection criteria.
3. CTS used for creation of ABAP development transport requests.The transaction code for this is SE10.
4. UserExits r used for adding additional functionality to the existing SAP standard transactions.Using UserExits we can add additional functionality standard SAP functionality without making any changes to the original code.BADI is a standardized interface for ABAP sources that enables partners and customers to enhance SAP-delivered programs in their namespace.
5 .We can identify User exits by using transactions CMOD and SMOD.
6. After entering transaction code SE10 select the transport request which u want to transport and click on transport icon(Truck symbol) to release it.
10. Purchase Requistion->RFQ->Vendor Evaluation->Purchase Order(ME21).
14. Table control is the only facility provide thru dialog programming when we come acrosse the use of updating standared,deletion,insertion and all database operations.
15. Field symbols r pointers to the existing data types(like 'C') which does not allocate any memory space. These are used faster access of data.
Answers to some ABAP Interview Questions:
Questions which I have faced in an interview:
1) What is runtime analysis? Have you used this?
2) What is meant by performance analysis? Have done anything to improve the performance?
3) How to transfer the objects? Have to transferred any objects?
4) How did you test the developed objects?
5) What is the difference between SAP Memory and ABAP Memory?
6) In order to upload Purchase order details, how you handle multiple values for a single field?
Eg: Item field may contain no. of values for a record
7) What is the procedure you followed to upload the data?
8) How did you handle errors in Call Transaction?
9) Among the Call Transaction and Session Method, which is faster?
10) What are the difference between Interactive and Drill Down Reports?
11) How to pass the variables to forms?
12) How to create a link between modified form and modified print program?
13) What is the table, which contain the details of all the name of the programs and forms?
14) How did you test the form u developed? How did you taken print?
15) What are Standard Texts?
16) What is the difference between Clustered Tables and Pooled Tables?
17) What is pf-status?
18) Among "Move" and "Move Corresponding", which is efficient one?
19) What are the output type and Tcodes?
20) Where we use Chain and Endchain?
21) Do you use select statement in loop endloop, how will be the performance? To improve the performance?
22) In select-options, how to get the default values as current month first date and last date by default?
Eg: 1/12/2004 and 31/12/2004
Go thru these answers:
1) What is runtime analysis? Have you used this?
It's checks program execution time in microseconds. When you go to se30.if you give desired program name in performance file. It will take you to below screen. You can get how much past is your program.
2) What is meant by performance analysis? Have done
3) How to transfer the objects? Have you transferred any objects?
4) How did you test the developed objects?
I was testing a developed object. There are two types of testing
Negative testing
Positive testing
In negative testing we will give negative data in input and we check any errors occurs.
In positive testing we will give positive data in input for checking errors.
8) How did you handle errors in Call Transaction?
We can create a internal table like 'bsgmcgcoll'. All the messages will go to internal table. We can get errors in this internal table.
Below messages are go to internal table. when you run the call transaction.
Message type
Message id
Message Number
Variable1
Variable2
Variable3
9) Among the Call Transaction and Session Method, which is faster?
Call transaction is faster then session method. But usually we use session method in real time...because we can transfer large amount of data from internal table to database and if any errors in a session. Process will not complete until session get correct.
10) What are the difference between Interactive and Drill Down Reports?
ABAP/4 provides some interactive events on lists such as AT LINE-SELECTION (double click) or AT USER-COMMAND (pressing a button). You can use these events to move through layers of information about individual items in a list.
Drill down report is nothing but interactive report...drilldown means above paragraph only.
11) How to pass the variables to forms?
12) What is the table, which contain the details of all the name of the programs and forms?
Table contains vertical and horizontal lines. We can store the data in table as blocks. We can scroll depends upon your wish. And these all are stored in database (data dictionary).
Which contain the details of all the name of the programs and forms? (I don't know).
13) How did you test the form u developed? How did you taken print?
14) What are Standard Texts?
16) What is the difference between Clustered Tables and Pooled Tables?
A pooled table is used to combine several logical tables in the ABAP/4 dictionary. Pooled tables are logical tables that must be assigned to a table pool when they are defined.
Cluster table are logical tables that must be assigned to a table cluster when they are defined.
Cluster table can be used to store control data they can also used to store temporary data or text such as documentation.
17) What is pf-status?
Pf status is used in interactive report for enhancing the functionality. If we go to se41, we can get menus, items and different function keys, which we are using for secondary list in interactive report.
18) Among "Move" and "Move Corresponding", which is efficient one?
I guess, 'move corresponding' is very efficient then 'move' statement. Because usually we use this stamtent for internal table fields only...so if we give move corresponding. Those fields only moving to other place (what ever you want).
19) What are the output type and Tcodes?
20) Where we use Chain and End chain?
21) Do you use select statement in loop end loop, how will be the performance? To improve the performance?
22) In select-options, how to get the default values as current month first date and last date by default?
Eg: 1/12/2004 and 31/12/2004
SAP ABAP interview questions
Thanks to the reader who sent in this question set:
1. What is an ABAP data dictionary?- ABAP 4 data dictionary describes the logical structures of the objects used in application development and shows how they are mapped to the underlying relational database in tables/views.
2. What are domains and data element?- Domains:Domain is the central object for describing the technical characteristics of an attribute of an business objects. It describes the value range of the field. Data Element: It is used to describe the semantic definition of the table fields like description the field. Data element describes how a field can be displayed to end-user.
3. What is foreign key relationship?- A relationship which can be defined between tables and must be explicitly defined at field level. Foreign keys are used to ensure the consistency of data. Data entered should be checked against existing data to ensure that there are now contradiction. While defining foreign key relationship cardinality has to be specified. Cardinality mentions how many dependent records or how referenced records are possible.
4. Describe data classes.- Master data: It is the data which is seldomly changed. Transaction data: It is the data which is often changed. Organization data: It is a customizing data which is entered in the system when the system is configured and is then rarely changed. System data:It is the data which R/3 system needs for itself.
5. What are indexes?- Indexes are described as a copy of a database table reduced to specific fields. This data exists in sorted form. This sorting form ease fast access to the field of the tables. In order that other fields are also read, a pointer to the associated record of the actual table are included in the index. Yhe indexes are activated along with the table and are created automatically with it in the database.
6. Difference between transparent tables and pooled tables.- Transparent tables: Transparent tables in the dictionary has a one-to-one relation with the table in database. Its structure corresponds to single database field. Table in the database has the same name as in the dictionary. Transparent table holds application data. Pooled tables. Pooled tables in the dictionary has a many-to-one relation with the table in database. Table in the database has the different name as in the dictionary. Pooled table are stored in table pool at the database level.
7. What is an ABAP/4 Query?- ABAP/4 Query is a powerful tool to generate simple reports without any coding. ABAP/4 Query can generate the following 3 simple reports: Basic List: It is the simple reports. Statistics: Reports with statistical functions like Average, Percentages. Ranked Lists: For analytical reports. - For creating a ABAP/4 Query, programmer has to create user group and a functional group. Functional group can be created using with or without logical database table. Finally, assign user group to functional group. Finally, create a query on the functional group generated.
8. What is BDC programming?- Transferring of large/external/legacy data into SAP system using Batch Input programming. Batch input is a automatic procedure referred to as BDC(Batch Data Communications).The central component of the transfer is a queue file which receives the data vie a batch input programs and groups associated data into sessions.
9. What are the functional modules used in sequence in BDC?- These are the 3 functional modules which are used in a sequence to perform a data transfer successfully using BDC programming: BDC_OPEN_GROUP - Parameters like Name of the client, sessions and user name are specified in this functional modules. BDC_INSERT - It is used to insert the data for one transaction into a session. BDC_CLOSE_GROUP - This is used to close the batch input session.
10. What are internal tables?- Internal tables are a standard data type object which exists only during the runtime of the program. They are used to perform table calculations on subsets of database tables and for re-organising the contents of database tables according to users need.
11. What is ITS? What are the merits of ITS?- ITS is a Internet Transaction Server. ITS forms an interface between HTTP server and R/3 system, which converts screen provided data by the R/3 system into HTML documents and vice-versa. Merits of ITS: A complete web transaction can be developed and tested in R/3 system. All transaction components, including those used by the ITS outside the R/3 system at runtime, can be stored in the R/3 system. The advantage of automatic language processing in the R/3 system can be utilized to language-dependent HTML documents at runtime.
12. What is DynPro?- DynPro is a Dynamic Programming which is a combination of screen and the associated flow logic Screen is also called as DynPro.
13. What are screen painter and menu painter?- Screen painter: Screen painter is a tool to design and maintain screen and its elements. It allows user to create GUI screens for the transactions. Attributes, layout, filed attributes and flow logic are the elements of Screen painter. Menu painter: Menu painter is a tool to design the interface components. Status, menu bars, menu lists, F-key settings, functions and titles are the components of Menu painters. Screen painter and menu painter both are the graphical interface of an ABAP/4 applications.
14. What are the components of SAP scripts?- SAP scripts is a word processing tool of SAP which has the following components: Standard text. It is like a standard normal documents. Layout sets. - Layout set consists of the following components: Windows and pages, Paragraph formats, Character formats. Creating forms in the R/3 system. Every layout set consists of Header, paragraph, and character string. ABAP/4 program.
15. What is ALV programming in ABAP? When is this grid used in ABAP?- ALV is Application List viewer. Sap provides a set of ALV (ABAP LIST VIEWER) function modules which can be put into use to embellish the output of a report. This set of ALV functions is used to enhance the readability and functionality of any report output. Cases arise in sap when the output of a report contains columns extending more than 255 characters in length. In such cases, this set of ALV functions can help choose selected columns and arrange the different columns from a report output and also save different variants for report display. This is a very efficient tool for dynamically sorting and arranging the columns from a report output. The report output can contain up to 90 columns in the display with the wide array of display options.
16. What are the events in ABAP/4 language?- Initialization, At selection-screen, Start-of-selection, end-of-selection, top-of-page, end-of-page, At line-selection, At user-command, At PF, Get, At New, At LAST, AT END, AT FIRST.
17. What is CTS and what do you know about it?- The Change and Transport System (CTS) is a tool that helps you to organize development projects in the ABAP Workbench and in Customizing, and then transport the changes between the SAP Systems and clients in your system landscape. This documentation provides you with an overview of how to manage changes with the CTS and essential information on setting up your system and client landscape and deciding on a transport strategy. Read and follow this documentation when planning your development project.
18. What are logical databases? What are the advantages/ dis-advantages of logical databases?- To read data from a database tables we use logical database. A logical database provides read-only access to a group of related tables to an ABAP/4 program. Advantages: i)check functions which check that user input is complete, correct,and plausible. ii)Meaningful data selection. iii)central authorization checks for database accesses. iv)good read access performance while retaining the hierarchical data view determined by the application logic. dis advantages: i)If you donot specify a logical database in the program attributes,the GET events never occur. ii)There is no ENDGET command,so the code block associated with an event ends with the next event statement (such as another GET or an END-OF-SELECTION).
19. What is a batch input session?- BATCH INPUT SESSION is an intermediate step between internal table and database table. Data along with the action is stored in session ie data for screen fields, to which screen it is passed, program name behind it, and how next screen is processed.
20. How to upload data using CATT ?- These are the steps to be followed to Upload data through CATT: Creation of the CATT test case & recording the sample data input. Download of the source file template. Modification of the source file. Upload of the data from the source file.
21. What is Smart Forms?- Smart Forms allows you to create forms using a graphical design tool with robust functionality, color, and more. Additionally, all new forms developed at SAP will be created with the new Smart Form solution.
22. How can I make a differentiation between dependent and independent data?- Client dependent or independent transfer requirements include client specific or cross client objects in the change requests. Workbench objects like SAPscripts are client specific, some entries in customizing are client independent. If you display the object list for one change request, and then for each object the object attributes, you will find the flag client specific. If one object in the task list has this flag on, then that transport will be client dependent.
23. What is the difference between macro and subroutine? - Macros can only be used in the program the are defined in and only after the definition are expanded at compilation / generation. Subroutines (FORM) can be called from both the program the are defined in and other programs . A MACRO is more or less an abbreviation for some lines of code that are used more than once or twice. A FORM is a local subroutine (which can be called external). A FUNCTION is (more or less) a subroutine that is called external. Since debugging a MACRO is not really possible, prevent the use of them (Ive never used them, but seen them in action). If the subroutine is used only local (called internal) use a FORM. If the subroutine is called external (used by more than one program) use a FUNCTION.

Regarding an Interview i came across..
Iam currently seeking a contract job in sap security area, last week (on Thursday) I had an interview(telephonic), well it was quite different from the traditional interviews,at the first instance after our introductions to each other, interviewer asked me to pose her any question,well I asked here about their work environment and then about the job role they are offering. The interview was quite interesting and I enjoyed talking to her. At the end of the interview, she gave me her contact number and told me to call her to clarify any doubts etc. Well its very unusual where an interviewer trying to have any contact with the candidate. Here my question is what can I assume that she is expecting from me? Is she just trying to develop a relationship on a profession basis? or is it a kind of test to judge me? Well Iam expecting the interview result this coming week,hoping for the best.

what is difference between stock and consumable material?
How to cancel an invoice,GR,PO,PR,PIR?
What questions we may expect for interview in MM nad for written test alsoHi,
Answer to your first question form material valuation point of view.
1. Difference between Stock and consumables materials.
Automatic account assignment occurs for a stock material with a material type that allows for inventory management. At posting time, data from the material master record determines which G/L accounts to hit. For automatic account assignment, the account assignment category field is left blank.
For consumable material may or may not have a material master record. A consumable material with a material master record would be for example, a material whose material type does not allow for inventory management (ex: pencils, paper, staplers, etc.). When creating a requisition for one of these consumable materials, you must enter something in the account assignment category field.
When an account assignment category is specified, an additional pop-up window appears for entering the account assignment data.

AActually, no. Just need time to get to your post. If you have not had your interview already try this.
One, bone up on your basic program structures.
Know basic keywords, etc.
Have your books in front of you and open to some topics that seem like test questions.
Review the content of the books that are pertinent. Prepare for the interview like you would a test.
ABOVE ALL - RELAX, sound confident that if you do not know the answer now you can look it up. This is an entry level position - They do not expect you to know everything - just have a basic understanding and be able to go from there.
Do not be afraid to say "I don't know but I know where to look in xxxx book".
Sorry, been busy today just got to forums.
If you posted without allowing a few hours for a reply then .... -

Hi Friends,
I was face some Interview.
Please send answers to the questions?
How many data Fields and key fields we can create in DSO?
You can overwrite key fields or Data Fields?
Which up date we use in Delta queue extraction( v1 or v2 or v3)
Which message we get when transported request is failed?
what is the Structural difference between Infoucbe and DSO
Data Loading is taking huge time when we extract data from source system to BI system/ how to solve?(Before it took 3-4 Hours now data loading takes 4 days)What is the difference between Display Attribute and
Navigational Attribute? How to make display attribute and navigational
attribute?
How to load flat file data?
How to load Hierarchy file data?
What is HACR?
How to maintain HACR?
If any issue in HACR then how to resolve the issue?
What is Baby Cube?
Why we are creating Aggregates?
What is the use of Aggregates?
Is there
any particular field on that we can create Aggregates or we can maintain
Aggregate on any field?
What is
the different DSO available? And what is the difference between those DSO?
What is
replacement path?
What are
the extractor types?
• Application Specific
o BW Content FI, HR, CO, SAP CRM, LO Cockpit
o Customer-Generated Extractors
LIS, FI-SL, CO-PA
• Cross Application (Generic Extractors)
o DB View, InfoSet, Function Module
2. What are the steps involved in LO Extraction?
• The steps are:
o RSA5 Select the DataSources
o LBWE Maintain DataSources and Activate Extract Structures
o LBWG Delete Setup Tables
o 0LI*BW Setup tables
o RSA3 Check extraction and the data in Setup tables
o LBWQ Check the extraction queue
o LBWF Log for LO Extract Structures
o RSA7 BW Delta
Queue Monitor
3. How to create a connection with LIS InfoStructures?
• LBW0 Connecting LIS InfoStructures to BW
4. What is the difference between ODS and InfoCube and MultiProvider?
• ODS: Provides granular data, allows overwrite and data is in transparent
tables, ideal for drilldown and RRI.
• CUBE: Follows the star schema, we can only append data, ideal for primary
reporting.
• MultiProvider: Does not have physical data. It allows to access data from
different InfoProviders (Cube, ODS, InfoObject). It is also preferred for
reporting.
5. What are Start routines, Transfer routines and Update routines?
• Start Routines: The start routine is run for each DataPackage after the data
has been written to the PSA and before the transfer rules have been executed.
It allows complex computations for a key figure or a characteristic. It has no
return value. Its purpose is to execute preliminary calculations and to store
them in global DataStructures. This structure or table can be accessed in the
other routines. The entire DataPackage in the transfer structure format is used
as a parameter for the routine.
• Transfer / Update Routines: They are defined at the InfoObject level. It is
like the Start Routine. It is independent of the DataSource. We can use this to
define Global Data and Global Checks.
6. What is the difference between start routine and update routine, when, how
and why are they called?
• Start routine can be used to access InfoPackage while update routines are
used while updating the Data Targets.
7. What is the table that is used in start routines?
• Always the table structure will be the structure of an ODS or InfoCube. For
example if it is an ODS then active table structure will be the table.
8. Explain how you used Start routines in your project?
• Start routines are used for mass processing of records. In start routine all
the records of DataPackage is available for processing. So we can process all
these records together in start routine. In one of scenario, we wanted to apply
size % to the forecast data. For example if material M1 is forecasted to say
100 in May. Then after applying size %(Small 20%, Medium 40%, Large 20%, Extra
Large 20%), we wanted to have 4 records against one single record that is
coming in the info package. This is achieved in start routine.
9. What are Return Tables?
• When we want to return multiple records, instead of single value, we use the
return table in the Update Routine. Example: If we have total telephone expense
for a Cost Center, using a return table we can get
expense per employee.
10. How do start routine and return table synchronize with each other?
• Return table is used to return the Value following the execution of start
routine
11. What is the difference
between V1, V2 and V3 updates?
• V1 Update: It is a Synchronous update. Here the Statistics update is carried
out at the same time as the document update (in the application
tables).
• V2 Update: It is an Asynchronous update. Statistics update and the Document
update take place as different tasks.
o V1 & V2 don't need scheduling.
• Serialized V3 Update: The V3 collective update must be scheduled as a job
(via LBWE). Here, document data is collected in the order it was created and
transferred into the BW as a batch job. The transfer sequence may not be the
same as the order in which the data was created in all scenarios. V3 update
only processes the update data that is successfully processed with the V2
update.
12. What is compression?
• It is a process used to delete the Request IDs and this saves space.
13. What is Rollup?
• This is used to load new DataPackages (requests) into the InfoCube
aggregates. If we have not performed a rollup then the new InfoCube data will
not be available while reporting on the aggregate.
14. What is table partitioning and what are the benefits of partitioning in an
InfoCube?
• It is the method of dividing a table which would enable a quick reference.
SAP uses fact file partitioning to improve performance. We can partition only
at 0CALMONTH or 0FISCPER. Table partitioning helps to run the report faster as
data is stored in the relevant partitions. Also table maintenance becomes
easier. Oracle,
Informix, IBM DB2/390 supports table partitioning while SAP DB, Microsoft SQL
Server, IBM DB2/400 do not support table portioning.
15. How many extra partitions are created and why?
• Two partitions are created for date before the begin date and after the end
date.
16. What are the options available in transfer rule?
• InfoObject
• Constant
• Routine
• Formula
17. How would you optimize the dimensions?
• We should define as many dimensions as possible and we have to take care that
no single dimension crosses more than 20% of the fact table size.
18. What are Conversion Routines for units and currencies in the update rule?
• Using this option we can write ABAP
code for Units / Currencies conversion. If we enable this flag then unit of Key
Figure appears in the ABAP code as an additional parameter. For example, we can
convert units in Pounds to Kilos.
19. Can an InfoObject be an InfoProvider, how and why?
• Yes, when we want to report on Characteristics or Master Data. We have to
right click on the InfoArea and select "Insert characteristic as data
target". For example, we can make 0CUSTOMER as an InfoProvider and report
on it.
20. What is Open Hub Service?
• The Open Hub Service enables us to distribute data from an SAP BW system into
external Data Marts, analytical applications, and other applications. We can
ensure controlled distribution using several systems. The central object for
exporting data is the InfoSpoke. We can define the source and the target object
for the data. BW becomes a hub of an enterprise data warehouse.
The distribution of data becomes clear through central monitoring from the
distribution status in the BW system.
21. How do you transform Open
Hub Data?
• Using BADI we can transform Open Hub Data according to the destination
requirement.
22. What is ODS?
• Operational DataSource is used for detailed storage of data. We can overwrite
data in the ODS. The data is stored in transparent tables.
23. What are BW Statistics and what is its use?
• They are group of Business Content InfoCubes which are used to measure
performance for Query and Load Monitoring. It also shows the usage of
aggregates, OLAP and Warehouse management
http://www.ittestpapers.com/articles/713/3/SAP-BW-Interview-Questions---Part-A/Page3.html
Communication Structure and Transfer
rules
• Create and InfoPackage
• Load Data
25. What are the delta options available when you load from flat file?
• The 3 options for Delta Management with Flat Files:
o Full Upload
o New Status for Changed records (ODS Object only)
o Additive Delta (ODS Object & InfoCube)
Q) Under which menu path is the Test Workbench to be found, including in
earlier Releases?
The menu path is: Tools - ABAP Workbench - Test - Test Workbench.
Q) I want to delete a BEx query that is in Production system through request. Is
anyone aware about it?
A) Have you tried the RSZDELETE transaction?
Q) Errors while monitoring process chains.
A) During data loading. Apart from them, in process chains you add so many
process types, for example after loading data into Info Cube, you rollup data
into aggregates, now this rolling up of data into aggregates is a process type
which you keep after the process type for loading data into Cube. This rolling
up into aggregates might fail.
Another one is after you load data into ODS, you activate ODS data (another
process type) this might also fail.
Q) In Monitor----- Details (Header/Status/Details) à Under Processing (data
packet): Everything OK à Context menu of Data Package 1 (1 Records): Everything
OK ---- Simulate update. (Here we can debug update rules or transfer rules.)
SM50 à Program/Mode à Program à Debugging & debug this work process.
Q) PSA Cleansing.
A) You know how to edit PSA. I don't think you can delete single records. You
have to delete entire PSA data for a request.
Q) Can we make a datasource to support delta.
A) If this is a custom (user-defined) datasource you can make the datasource
delta enabled. While creating datasource from RSO2, after entering datasource
name and pressing create, in the next screen there is one button at the top,
which says generic delta. If you want more details about this there is a
chapter in Extraction book, it's in last pages u find out.
Generic delta services: -
Supports delta extraction for generic extractors according to:
Time stamp
Calendar day
Numeric pointer, such as document number & counter
Only one of these attributes can be set as a delta attribute.
Delta extraction is supported for all generic extractors, such as tables/views,
SAP Query and function modules
The delta queue (RSA7) allows you to monitor the current status of the delta
attribute
Q) Workbooks, as a general rule, should be transported with the
role.
Here are a couple of scenarios:
1. If both the workbook and its role have been previously transported, then the
role does not need to be part of the transport.
2. If the role exists in both dev and the target system but the workbook has
never been transported, and then you have a choice of transporting the role
(recommended) or just the workbook. If only the workbook is transported, then
an additional step will have to be taken after import: Locate the WorkbookID
via Table RSRWBINDEXT (in Dev and verify the same exists in the target system)
and proceed to manually add it to the role in the target system via Transaction
Code PFCG -- ALWAYS use control c/control v copy/paste for manually adding!
3. If the role does not exist in the target system you should transport both
the role and workbook. Keep in mind that a workbook is an object unto itself
and has no dependencies on other objects. Thus, you do not receive an error
message from the transport of 'just a workbook' -- even though it may not be
visible, it will exist (verified via Table RSRWBINDEXT).
Overall, as a general rule, you should transport roles with workbooks.
Q) How much time does it take to extract 1 million (10 lackhs) of records into
an infocube?
A. This depends, if you have complex coding in update rules it will take longer
time, or else it will take less than 30 minutes.
Q) What are the five ASAP Methodologies?
A: Project plan, Business Blue print, Realization, Final preparation & Go-Live - support.
1. Project Preparation: In this phase, decision makers define clear project
objectives and an efficient decision making process ( i.e. Discussions with the
client, like what are his needs and requirements etc.). Project managers
will be involved in this phase (I guess).
A Project Charter is issued and an implementation strategy is outlined in this
phase.
2. Business Blueprint: It is a detailed documentation of your company's
requirements. (i.e. what are the objects we need to develop are modified
depending on the client's requirements).
3. Realization: In this only, the implementation of the project takes place (development
of objects etc) and we are involved in the project from here only.
4. Final Preparation: Final preparation before going live i.e. testing,
conducting pre-go-live, end user training etc.
End user training is given that is in the client site you train them how to
work with the new environment, as they are new to the technology.
5. Go-Live & support: The project has gone live and it is into production.
The Project team will be supporting the end users.
Q) What is landscape of R/3 & what is landscape of BW. Landscape of R/3 not
sure.
Then Landscape of b/w: u have the development system, testing system, production system
Development system: All the implementation part is done in this sys. (I.e.,
Analysis of objects developing, modification etc) and from here the objects are
transported to the testing system, but before transporting an initial test
known as Unit testing
(testing of objects) is done in the development sys.
Testing/Quality system: quality check is done in this system and integration
testing is done.
Production system: All the extraction part takes place in this sys.
Q) How do you measure the size of infocube?
A: In no of records.
Q). Difference between infocube and ODS?
A: Infocube is structured as star schema (extended) where a fact table is
surrounded by different dim table that are linked with DIM'ids. And the data
wise, you will have aggregated data in the cubes. No overwrite functionality
ODS is a flat structure (flat table) with no star schema concept and which will
have granular data (detailed level). Overwrite functionality.
Flat file
datasources does not support 0recordmode in extraction.
x before, -after, n new, a add, d delete, r reverse
Q) Difference between display attributes and navigational attributes?
A: Display attribute is one, which is used only for display purpose in the
report. Where as navigational attribute is used for drilling down in the
report. We don't need to maintain Navigational attribute in the cube as a
characteristic (that is the advantage) to drill down.
Q. SOME DATA IS UPLOADED TWICE INTO INFOCUBE. HOW TO CORRECT IT?
A: But how is it possible? If you load it manually twice, then you can delete
it by requestID.
Q. CAN U ADD A NEW FIELD AT THE ODS LEVEL?
Sure you can. ODS is nothing but a table.
Q. CAN NUMBER OF DATASOURCES HAVE ONE INFOSOURCE?
A) Yes of course. For example, for loading text and hierarchies we use
different data sources but the same InfoSource.
Q. BRIEF THE DATAFLOW IN BW.
A) Data flows from transactional system to analytical system (BW). DataSources
on the transactional system needs to be replicated on BW side and attached to
infosource and update rules respectively.
Q. CURRENCY CONVERSIONS CAN BE WRITTEN IN UPDATE RULES. WHY NOT IN TRANSFER
RULES?
Q) WHAT IS PROCEDURE TO UPDATE DATA INTO DATA TARGETS?
FULL and DELTA.
Q) AS WE USE Sbwnn, sbiw1, sbiw2 for delta update in LIS THEN
WHAT IS THE PROCEDURE IN LO-COCKPIT?
No LIS in LO cockpit. We will have datasources and can be maintained (append
fields). Refer white paper
on LO-Cockpit extractions.
Q) Why we delete the setup tables (LBWG) & fill them (OLI*BW)?
A) Initially we don't delete the setup tables but when we do change in extract
structure we go for it. We r changing the extract structure right, that means
there are some newly added fields in that which r not before. So to get the
required data ( i.e.; the data which is required is taken and to avoid
redundancy) we delete n then fill the setup tables.
To refresh the statistical data.
The extraction set up reads the dataset that you want to process such as,
customers orders with the tables like VBAK, VBAP) & fills the relevant communication
structure with the data. The data is stored in cluster
tables from where it is read when the initialization is run. It is important
that during initialization phase, no one generates or modifies application
data, at least until the tables can be set up.
Q) SIGNIFICANCE of ODS?
It holds granular data (detailed level).
Q) WHERE THE PSA DATA IS STORED?
In PSA table.
Q) WHAT IS DATA SIZE?
The volume of data one data target holds (in no. of records)
Q) Different types of INFOCUBES.
Basic, Virtual (remote, sap remote and multi)
Virtual Cube is used for example, if you consider railways reservation all the
information has to be updated online. For designing the Virtual cube you have
to write the function module that is linking to table, Virtual cube it is like
a the structure, when ever the table is updated the virtual cube will fetch the
data from table and display report Online... FYI.. you will get the information
: https://www.sdn.sap.com/sdn
/index.sdn and search for Designing Virtual Cube and you will get
a good material designing the Function Module
Q) INFOSET QUERY.
Can be made of ODS's and Characteristic InfoObjects with masterdata.
Q) IF THERE ARE 2 DATASOURCES HOW MANY TRANSFER STRUCTURES ARE THERE.
In R/3 or in BW? 2 in R/3 and 2 in BW
Q) ROUTINES?
Exist in the InfoObject, transfer routines, update routines and start routine
Q) BRIEF SOME STRUCTURES USED IN BEX.
Rows and Columns, you can create structures.
Q) WHAT ARE THE DIFFERENT VARIABLES USED IN BEX?
Different Variable's are Texts, Formulas, Hierarchies, Hierarchy nodes &
Characteristic values.
Variable Types are
Manual entry /default value
Replacement path
SAP exit
Customer exit
Authorization
Q) HOW MANY LEVELS YOU CAN GO IN REPORTING?
You can drill down to any level by using Navigational attributes and jump
targets.
Q) WHAT ARE INDEXES?
Indexes are data base indexes, which help in retrieving data fastly.
Q) DIFFERENCE BETWEEN 2.1 AND 3.X VERSIONS.
Help! Refer documentation
Q) IS IT NESSESARY TO INITIALIZE EACH TIME THE DELTA UPDATE IS USED?
No.
Q) WHAT IS THE SIGNIFICANCE OF KPI'S?
KPI's indicate the performance of a company. These are key figures
Q) AFTER THE DATA EXTRACTION
WHAT IS THE IMAGE POSITION.
After image (correct me if I am wrong)
Q) REPORTING AND RESTRICTIONS.
Help! Refer documentation.
Q) TOOLS USED FOR PERFORMANCE TUNING.
ST22, Number ranges, delete indexes before load. Etc
Q) PROCESS CHAINS: IF U has USED IT THEN HOW WILL U SCHEDULING DATA DAILY.
There should be some tool to run the job daily (SM37 jobs)
Q) AUTHORIZATIONS.
Profile generator
Q) WEB REPORTING.
What are you expecting??
Q) CAN CHARECTERSTIC INFOOBJECT CAN BE INFOPROVIDER.
Of course
Q) PROCEDURES OF REPORTING ON MULTICUBES
Refer help. What are you expecting? MultiCube works on Union condition
Q) EXPLAIN TRANPSORTATION OF OBJECTS?
Dev---àQ and Dev-------àP
Q) What types of partitioning are there for BW?
There are two Partitioning Performance aspects for BW (Cube & PSA)
Query Data Retrieval
Performance Improvement:
Partitioning by (say) Date Range improves data retrieval by making best use of
database [data range] execution plans and indexes (of say Oracle database engine).
B) Transactional Load Partitioning Improvement:
Partitioning based on expected load volumes and data element sizes. Improves
data loading into PSA and Cubes by infopackages (Eg. without timeouts).
Q) How can I compare data in R/3 with data in a BW Cube after the daily delta
loads? Are there any standard procedures for checking them or matching the
number of records?
A) You can go to R/3 TCode RSA3 and run the extractor. It will give you the
number of records extracted. Then go to BW Monitor to check the number of
records in the PSA and check to see if it is the same & also in the monitor
header tab.
A) RSA3 is a simple extractor checker program that allows you to rule out
extracts problems in R/3. It is simple to use, but only really tells you if the
extractor works. Since records that get updated into Cubes/ODS structures are
controlled by Update Rules, you will not be able to determine what is in the
Cube compared to what is in the R/3 environment. You will need to compare
records on a 1:1 basis against records in R/3 transactions for the functional
area in question. I would recommend enlisting the help of the end user community
to assist since they presumably know the data.
To use RSA3, go to it and enter the extractor ex: 2LIS_02_HDR. Click execute
and you will see the record count, you can also go to display that data. You
are not modifying anything so what you do in RSA3 has no effect on data quality
afterwards. However, it will not tell you how many records should be expected
in BW for a given load. You have that information in the monitor RSMO during
and after data loads. From RSMO for a given load you can determine how many
records were passed through the transfer rules from R/3, how many targets were
updated, and how many records passed through the Update Rules. It also gives
you error messages from the PSA.
Q) Types of Transfer Rules?
A) Field to Field mapping, Constant, Variable & routine.
Q) Types of Update Rules?
A) (Check box), Return table
Q) Transfer Routine?
A) Routines, which we write in, transfer rules.
Q) Update Routine?
A) Routines, which we write in Update rules
Q) What is the difference between writing a routine in transfer rules and
writing a routine in update rules?
A) If you are using the same InfoSource to update data in more than one data
target its better u write in transfer rules because u can assign one InfoSource
to more than one data target & and what ever logic u write in update rules
it is specific to particular one data target.
Q) Routine with Return Table.
A) Update rules generally only have one return value. However, you can create a
routine in the tab strip key figure calculation, by choosing checkbox Return
table. The corresponding key figure routine then no longer has a return value,
but a return table. You can then generate as many key figure values, as you
like from one data record.
Q) Start routines?
A) Start routines u can write in both updates rules and transfer rules, suppose
you want to restrict (delete) some records based on conditions before getting
loaded into data targets, then you can specify this in update rules-start
routine.
Ex: - Delete Data_Package ani ante it will delete a record based on the
condition
Q) X & Y Tables?
X-table = A table to link material SIDs with SIDs for time-independent
navigation attributes.
Y-table = A table to link material SIDs with SIDS for time-dependent navigation
attributes.
There are four types of sid tables
X time independent navigational attributes sid tables
Y time dependent navigational attributes sid tables
H hierarchy sid tables
I hierarchy structure sid tables
Q) Filters & Restricted Key figures (real time example)
Restricted KF's u can have for an SD cube: billed quantity, billing value, no:
of billing documents as RKF's.
Q) Line-Item Dimension (give me an real time example)
Line-Item Dimension: Invoice no: or Doc no: is a real time example
Q) What does the number in the 'Total' column in Transaction RSA7 mean?
A) The 'Total' column displays the number of LUWs that were written in the
delta queue and that have not yet been confirmed. The number includes the LUWs
of the last delta request (for repetition of a delta request) and the LUWs for
the next delta request. A LUW only disappears from the RSA7 display when it has
been transferred to the BW System and a new delta request has been received
from the BW System.
Q) How to know in which table (SAP BW) contains Technical Name / Description
and creation data of a particular Reports. Reports that are created using BEx
Analyzer.
A) There is no such table in BW if you want to know such details while you are
opening a particular query press properties button you will come to know all
the details that you wanted.
You will find your information about technical names and description about
queries in the following tables. Directory of all reports (Table RSRREPDIR) and
Directory of the reporting component elements (Table RSZELTDIR) for workbooks
and the connections to queries check Where- used list for reports in workbooks
(Table RSRWORKBOOK) Titles of Excel Workbooks in InfoCatalog (Table
RSRWBINDEXT)
Q) What is a LUW in the delta queue?
A) A LUW from the point of view of the delta queue can be an individual
document, a group of documents from a collective run or a whole data packet of
an application
extractor.
Q) Why does the number in the 'Total' column in the overview screen of
Transaction RSA7 differ from the number of data records that is displayed when
you call the detail view?
A) The number on the overview screen corresponds to the total of LUWs (see also
first question) that were written to the qRFC queue and that have not yet been
confirmed. The detail screen displays the records contained in the LUWs. Both,
the records belonging to the previous delta request and the records that do not
meet the selection conditions of the preceding delta init requests are filtered
out. Thus, only the records that are ready for the next delta request are
displayed on the detail screen. In the detail screen of Transaction RSA7, a
possibly existing customer exit is not taken into account.
Q) Why does Transaction RSA7 still display LUWs on the overview screen after
successful delta loading?
A) Only when a new delta has been requested does the source system learn that
the previous delta was successfully loaded to the BW System. Then, the LUWs of
the previous delta may be confirmed (and also deleted). In the meantime, the
LUWs must be kept for a possible delta request repetition. In particular, the
number on the overview screen does not change when the first delta was loaded
to the BW System.
Q) Why are selections not taken into account when the delta queue is filled?
A) Filtering according to selections takes place when the system reads from the
delta queue. This is necessary for reasons of performance.
Q) Why is there a DataSource with '0' records in RSA7 if delta exists and has
also been loaded successfully?
It is most likely that this is a DataSource that does not send delta data to
the BW System via the delta queue but directly via the extractor (delta for
master data using ALE change pointers). Such a DataSource should not be
displayed in RSA7. This error is corrected with BW 2.0B Support Package 11.
Q) Do the entries in table ROIDOCPRMS have an impact on the performance of the
loading procedure from the delta queue?
A) The impact is limited. If performance problems are related to the loading
process from the delta queue, then refer to the application-specific notes (for
example in the CO-PA area, in the logistics cockpit area and so on).
Caution: As of Plug In 2000.2 patch 3 the entries in table ROIDOCPRMS are as
effective for the delta queue as for a full update. Please note, however, that
LUWs are not split during data loading for consistency reasons. This means that
when very large LUWs are written to the DeltaQueue, the actual package size may
differ considerably from the MAXSIZE and MAXLINES parameters.
Q) Why does it take so long to display the data in the delta queue (for example
approximately 2 hours)?
A) With Plug In 2001.1 the display was changed: the user has the option of
defining the amount of data to be displayed, to restrict it, to selectively
choose the number of a data record, to make a distinction between the 'actual'
delta data and the data intended for repetition and so on.
Q) What is the purpose of function 'Delete data and meta data in a queue' in
RSA7? What exactly is deleted?
A) You should act with extreme caution when you use the deletion function in
the delta queue. It is comparable to deleting an InitDelta in the BW System and
should preferably be executed there. You do not only delete all data of this
DataSource for the affected BW System, but also lose the entire information
concerning the delta initialization. Then you can only request new deltas after
another delta initialization.
When you delete the data, the LUWs kept in the qRFC queue for the corresponding
target system are confirmed. Physical deletion only takes place in the qRFC
outbound queue if there are no more references to the LUWs.
The deletion function is for example intended for a case where the BW System,
from which the delta initialization was originally executed, no longer exists
or can no longer be accessed.
Q) Why does it take so long to delete from the delta queue (for example half a
day)?
A) Import PlugIn 2000.2 patch 3. With this patch the performance during
deletion is considerably improved.
Q) Why is the delta queue not updated when you start the V3 update in the
logistics cockpit area?
A) It is most likely that a delta initialization had not yet run or that the
delta initialization was not successful. A successful delta initialization (the
corresponding request must have QM status 'green' in the BW System) is a
prerequisite for the application data being written in the delta queue.
Q) What is the relationship between RSA7 and the qRFC monitor (Transaction
SMQ1)?
A) The qRFC monitor basically displays the same data as RSA7. The internal
queue name must be used for selection on the initial screen of the qRFC
monitor. This is made up of the prefix 'BW, the client and the short name of
the DataSource. For DataSources whose name are 19 characters long or shorter,
the short name corresponds to the name of the DataSource. For DataSources whose
name is longer than 19 characters (for delta-capable DataSources only possible
as of PlugIn 2001.1) the short name is assigned in table ROOSSHORTN.
In the qRFC monitor you cannot distinguish between repeatable and new LUWs.
Moreover, the data of a LUW is displayed in an unstructured manner there.
Q) Why are the data in the delta queue although the V3 update was not started?
A) Data was posted in background. Then, the records are updated directly in the
delta queue (RSA7). This happens in particular during automatic goods receipt
posting (MRRS). There is no duplicate transfer of records to the BW system. See
Note 417189.
Q) Why does button 'Repeatable' on the RSA7 data details screen not only show
data loaded into BW during the last delta but also data that were newly added,
i.e. 'pure' delta records?
A) Was programmed in a way that the request in repeat mode fetches both
actually repeatable (old) data and new data from the source system.
Q) I loaded several delta inits with various selections. For which one is the
delta loaded?
A) For delta, all selections made via delta inits are summed up. This means, a
delta for the 'total' of all delta initializations is loaded.
Q) How many selections for delta inits are possible in the system?
A) With simple selections (intervals without complicated join conditions or
single values), you can make up to about 100 delta inits. It should not be
more.
With complicated selection conditions, it should be only up to 10-20 delta
inits.
Reason: With many selection conditions that are joined in a complicated way,
too many 'where' lines are generated in the generated ABAP
source code that may exceed the memory limit.
Q) I intend to copy the source system, i.e. make a client copy. What will
happen with may delta? Should I initialize again after that?
A) Before you copy a source client or source system, make sure that your deltas
have been fetched from the DeltaQueue into BW and that no delta is pending.
After the client copy, an inconsistency might occur between BW delta tables and
the OLTP delta tables as described in Note 405943. After the client copy, Table
ROOSPRMSC will probably be empty in the OLTP since this table is
client-independent. After the system copy, the table will contain the entries
with the old logical system name that are no longer useful for further delta
loading from the new logical system. The delta must be initialized in any case
since delta depends on both the BW system and the source system. Even if no
dump 'MESSAGE_TYPE_X' occurs in BW when editing or creating an InfoPackage, you
should expect that the delta have to be initialized after the copy.
Q) Is it allowed in Transaction SMQ1 to use the functions for manual control of
processes?
A) Use SMQ1 as an instrument for diagnosis and control only. Make changes to BW
queues only after informing the BW Support or only if this is explicitly
requested in a note for component 'BC-BW' or 'BW-WHM-SAPI'.
Q) Despite of the delta request being started after completion of the
collective run (V3 update), it does not contain all documents. Only another
delta request loads the missing documents into BW. What is the cause for this
"splitting"?
A) The collective run submits the open V2 documents for processing to the task
handler, which processes them in one or several parallel update processes in an
asynchronous way. For this reason, plan a sufficiently large "safety time
window" between the end of the collective run in the source system and the
start of the delta request in BW. An alternative solution where this problem
does not occur is described in Note 505700.
Q) Despite my deleting the delta init, LUWs are still written into the
DeltaQueue?
A) In general, delta initializations and deletions of delta inits should always
be carried out at a time when no posting takes place. Otherwise, buffer
problems may occur: If a user started the internal mode at a time when the
delta initialization was still active, he/she posts data into the queue even
though the initialization had been deleted in the meantime. This is the case in
your system.
Q) In SMQ1 (qRFC Monitor) I have status 'NOSEND'. In the table TRFCQOUT, some
entries have the status 'READY', others 'RECORDED'. ARFCSSTATE is 'READ'. What
do these statuses mean? Which values in the field 'Status' mean what and which
values are correct and which are alarming? Are the statuses BW-specific or
generally valid in qRFC?
A) Table TRFCQOUT and ARFCSSTATE: Status READ means that the record was read
once either in a delta request or in a repetition of the delta request.
However, this does not mean that the record has successfully reached the BW
yet. The status READY in the TRFCQOUT and RECORDED in the ARFCSSTATE means that
the record has been written into the DeltaQueue and will be loaded into the BW
with the next delta request or a repetition of a delta. In any case only the
statuses READ, READY and RECORDED in both tables are considered to be valid.
The status EXECUTED in TRFCQOUT can occur temporarily. It is set before
starting a DeltaExtraction for all records with status READ present at that
time. The records with status EXECUTED are usually deleted from the queue in
packages within a delta request directly after setting the status before
extracting a new delta. If you see such records, it means that either a process
which is confirming and deleting records which have been loaded into the BW is
successfully running at the moment, or, if the records remain in the table for
a longer period of time with status EXECUTED, it is likely that there are
problems with deleting the records which have already been successfully been
loaded into the BW. In this state, no more deltas are loaded into the BW. Every
other status is an indicator for an error or an inconsistency. NOSEND in SMQ1
means nothing (see note 378903).
The value 'U' in field 'NOSEND' of table TRFCQOUT is discomforting.
Q) The extract structure was changed when the DeltaQueue was empty. Afterwards
new delta records were written to the DeltaQueue. When loading the delta into
the PSA, it shows that some fields were moved. The same result occurs when the
contents of the DeltaQueue are listed via the detail display. Why are the data
displayed differently? What can be done?
Make sure that the change of the extract structure is also reflected in the
database and that all servers are synchronized. We recommend to reset the
buffers using Transaction $SYNC. If the extract structure change is not
communicated synchronously to the server where delta records are being created,
the records are written with the old structure until the new structure has been
generated. This may have disastrous consequences for the delta.
When the problem occurs, the delta needs to be re-initialized.
Q) How and where can I control whether a repeat delta is requested?
A) Via the status of the last delta in the BW Request Monitor. If the request
is RED, the next load will be of type 'Repeat'. If you need to repeat the last
load for certain reasons, set the request in the monitor to red manually. For
the contents of the repeat see Question 14. Delta requests set to red despite
of data being already updated lead to duplicate records in a subsequent repeat,
if they have not been deleted from the data targets concerned before.
Q) As of PI 2003.1, the Logistic Cockpit offers various types of update
methods. Which update method is recommended in logistics? According to which
criteria should the decision be made? How can I choose an update method in
logistics?
See the recommendation in Note 505700.
Q) Are there particular recommendations regarding the data volume the
DeltaQueue may grow to without facing the danger of a read failure due to
memory problems?
A) There is no strict limit (except for the restricted number range of the
24-digit QCOUNT counter in the LUW management table - which is of no practical
importance, however - or the restrictions regarding the volume and number of
records in a database table).
When estimating "smooth" limits, both the number of LUWs is important
and the average data volume per LUW. As a rule, we recommend to bundle data
(usually documents) already when writing to the DeltaQueue to keep number of
LUWs small (partly this can be set in the applications, e.g. in the Logistics
Cockpit). The data volume of a single LUW should not be considerably larger
than 10% of the memory available to the work process for data extraction
(in a 32-bit architecture with a memory volume of about 1GByte per work
process, 100 Mbytes per LUW should not be exceeded). That limit is of rather
small practical importance as well since a comparable limit already applies
when writing to the DeltaQueue. If the limit is observed, correct reading is
guaranteed in most cases.
If the number of LUWs cannot be reduced by bundling application transactions,
you should at least make sure that the data are fetched from all connected BWs
as quickly as possible. But for other, BW-specific, reasons, the frequency
should not be higher than one DeltaRequest per hour.
To avoid memory problems, a program-internal limit ensures that never more than
1 million LUWs are read and fetched from the database per DeltaRequest. If this
limit is reached within a request, the DeltaQueue must be emptied by several
successive DeltaRequests. We recommend, however, to try not to reach that limit
but trigger the fetching of data from the connected BWs already when the number
of LUWs reaches a 5-digit value.
Q) I would like to display the date the data was uploaded on the
report. Usually, we load the transactional data nightly. Is there any easy way
to include this information on the report for users? So that they know the
validity of the report.
A) If I understand your requirement correctly, you want to display the date on
which data was loaded into the data target from which the report is being
executed. If it is so, configure your workbook to display the text elements in
the report. This displays the relevance of data field, which is the date on which
the data load has taken place.
Q) Can we filter the fields at Transfer Structure?
Q) Can we load data directly into infoobject with out extraction is it
possible.
Yes. We can copy from other infoobject if it is same. We load data from PSA if
it is already in PSA.
Q) HOW MANY DAYS CAN WE KEEP THE DATA IN PSA, IF WE R SHEDULED DAILY, WEEKLY
AND MONTHLY.
a) We can set the time.
Q) HOW CAN U GET THE DATA FROM CLIENT IF U R WORKING ON OFFSHORE PROJECTS.
THROUGH WHICH NETWORK.
a) VPN…………….Virtual
Private Network, VPN is nothing but one sort of network
where we can connect to the client systems sitting in offshore through RAS
(Remote access server).
Q) HOW CAN U ANALIZE THE PROJECT AT FIRST?
Prepare Project Plan and Environment
Define Project Management
Standards and
Procedures
Define Implementation Standards and Procedures
Testing & Go-live + supporting.
Q) THERE is one ODS AND 4 INFOCUBES. WE SEND DATA AT TIME TO ALL CUBES IF ONE
CUBE GOT LOCK ERROR. HOW CAN U RECTIFY THE ERROR?
Go to TCode sm66 then see which one is locked select that pid from there and
goto sm12
TCode then unlock it this is happened when lock errors are occurred when u
scheduled.
Q) Can anybody tell me how to add a navigational attribute in the BEx report in
the rows?
A) Expand dimension under left side panel (that is infocube panel) select than
navigational attributes drag and drop under rows panel.
Q) IF ANY TRASACTION CODE LIKE SMPT OR STMT.
In current systems (BW 3.0B and R/3 4.6B) these Tcodes don't exist!
Q) WHAT IS TRANSACTIONAL CUBE?
A) Transactional InfoCubes differ from standard InfoCubes in that the former
have an improved write access performance level. Standard InfoCubes are
technically optimized for read-only access and for a comparatively small number
of simultaneous accesses. Instead, the transactional InfoCube was developed to
meet the demands of SAP Strategic Enterprise Management (SEM), meaning that,
data is written to the InfoCube (possibly by several users at the same time)
and re-read as soon as possible. Standard Basic cubes are not suitable for
this.
Q) Is there any way to delete cube contents within update rules from an ODS
data source? The reason for this would be to delete (or zero out) a cube record
in an "Open Order" cube if the open order quantity was 0.
I've tried using the 0recordmode but that doesn't work. Also, would it
be easier to write a program that would be run after the load and delete
the records with a zero open qty?
A) START routine for update rules u can write ABAP code.
A) Yap, you can do it. Create a start routine in Update rule.
It is not "Deleting cube contents with update rules" It is only
possible to avoid that some content is updated into the InfoCube using the
start routine. Loop at all the records and delete the record that has the
condition. "If the open order quantity was 0" You have to think also
in before and after images in case of a delta upload. In that case you may
delete the change record and keep the old and after the change the wrong
information.
Q) I am not able to access a node in hierarchy directly using variables for
reports. When I am using Tcode RSZV it is giving a message that it doesn't
exist in BW 3.0 and it is embedded in BEx. Can any one tell me the other
options to get the same functionality in BEx?
A) Tcode RSZV is used in the earlier version of 3.0B only. From 3.0B onwards,
it's possible in the Query Designer (BEx) itself. Just right click on the
InfoObject for which you want to use as variables and precede further selecting
variable type and proce -
Hi All
I want ABAP-HR interview questions,I am attending my first abap-hr interview on thursday,
So i want what type of question i can expect from the interviewer.
If any one plz send to my mail.
Thanks in advanceHi Chris
Keep up the comments as you are the only one that seems to willing to call out folks on the board.
Just yesterday I saw a question saying something of the effect " I am a consultant and the client is asking me to prepare configuration material on garnishment and taxes please help"
I almost did a "Chris" response but decided to hold tight and just say nothing though part of me wishes I have the clients email address so they could be aware of what a joker they are paying to help them.

Dataguard Interview questions and most frequeently asked DG issues
Hi Gurus,
I am new to this forum and happy to be a part of it.
Can someone help me in posting " Dataguard Interview questions and most frequeently asked DG issues" as i am preparing for the interviews.
And also share the enhancements to DG in 11g.
Thanks in advance.I'm not impressed by any of the questions at any of the linked sites provided so here are the one's I would expect someone to be able to answer:
1. What is the difference between Physical and Logical Data Guard in terms of how they work and how they are used in the enterprise?
2. What is the difference between vanilla Data Guard and Active and Snapshot?
3. How do you enable the Data Guard Broker process and why and when would you want to?
4. Who is Larry Carpenter and why should you care?
5. What parameters in using orapwd are critical for success?
6. What would you recommend as a value for SEND_BUF_SIZE and why?
7. Given a primary production database, and a full RMAN backup that takes 1 hour to fully restore ... how long would it take you to implement Physical Data Guard from the time you started working?
If the answer to question 7 is greater than 2 hours ... my assumption would be that you probably had never done it before and it wouldn't matter that you got the first six questions correct. -
Automatic payment program how to explain in interviewes
hi friends
asking automatic payment program explanation in interviewes. how to explain the automatic payment program pls tell me my mail id [email protected]The payment program can be broken down into the following steps:
1. Define parameters (Parameters TAB on the F110 screen)- Based on the parameters defined the program picks up the vendor 'open' items to be paid and displays them in the payment proposal. The parameters tell the program the following:
a. Which company codes you want to include in this payment run (If the AP cleark who is running the program is responsible for only North American companies, he/she will include only those company codes in the payment run)
b. Which Vendor you want to pay (suppose there are lot of AP clerks in an organization, they can use this to restrict the selection to the vendor for whom they are responsible for payment)
c. What are the payment methods you want to use to pay these vendors
d. What is the next date when you will run payment run. Based on this date the program picks up all the items which become due till the next date of payment run, even though those open items are not due today.
2. Free selection TAB - In this TAB you can restrict the 'open' items you want to select. You can use any field in the BSEG table and restrict the selection. For e.g. You can select the field ' Document no.' from BSEG and give a range of documents you want to pay. The program will pick up only those documents for payment.
3. Additional Log TAB - In this TAB you can select the logs you want the system to create if there are any errors or for all items even if there are no errors. If the results of the program is not what you expected, then you can read the log to understand the reason why the program did not select what you wanted.
4. Print/data medium TAB - Here you supply the program variant for all the payment methods you are using. For e.g. in US if you use the 'Check' payment method, then in this TAB you supply the variant for the RFFOUS_C program. If you are using EDI payment method then a variant for the program RFFOEDI1 has to be supplied in this TAB.
5. Status TAB - Once you enter all the information in the above 4 TAB's you will come to the status TAB.
Initial status will be 'No Parameters have been entered'
Before you run the program, the status would be 'Parameters have been defined'.
After you run the proposal the status will change to 'Payment proposal has been created'.
After you run the Payment run the status will change to 'Payment run has been carried out. Posting orders: 10 generated, 10 completed'.
Thus the status tells you in what stage of the Payment program you are in.
Please note that the buttons you see here is dynamic. Based on the status the button will appear or disappear. But all the functionalities which these buttons offer can also be selected using the dropdown list appearing at the top of the screen.
6. After you completed the payment run, you have to print the payment media - If the payment method used is check, you print checks. If it is wire then you create the wire file etc. This is the last step in the payment run.
Important Note: After running the proposal, you should not leave the payment program. Either you should complete the payment run completely , all the way till you print the payment media, or delete the payment proposal.
If you do not delete the proposal, then the vendors in this proposal will not be included in any of the subsequent payment runs.
Hope this helps you in answering your Interview questions.
Good luck.

Questions about expected Java expertise
Hi,
For last 8 years I have been doing multimedia and web programming using Microsoft technologies. I have seen a job which is asking for a minimum of 6 months of experience in developing applications using Java 2 platform. They expect to have experience with Java Swing, JSP, J2EE, PowerBuilder, RDBMS, UML, HTML, XML and ASP.
It seems that they have web and non-web applications. Can someone tell me what kind of expertise someone with 6 months of experience will have with Java 2 platform keeping in view the above information?
I am comfortable with ASP but new to Java world. If you were conducting interviews what level of expertise would you expect?
Thanks for your time and comments,

Pls answer this interview question?
Hi,
i have attended the interview over the past few months ago so that they are asked
like
question 1)
a table has 1million rows because that will take more time to retrieve user says to improve the performance of that table .... in which way you would handle in PLSQL programming or concept anyway..
Pls revert back to me if you know anything about..............Bluntly put. I will tell that user that he/she has no concept about performance or tables and instead of telling me how to do my job ("make that table faster!"), to explain his/her business requirement in order for me to build a technical solution that satisfies that requirement.
Of course, I will do that more diplomatically in an interview.
I can guess what the interviewers were after - they were probing PL/SQL expertise ito making PL/SQL code faster. E.g. using bulk processing to reduce context switching, or (my favourite) to reduce PL/SQL and increase SQL.
But they are missing the fact that
a) the size of the table does not determine performance
b) the amount of I/O does
The amount of I/O is directly relates to:
i) the structure of the table
ii) the amount of data requested in the SQL selection and projection
But no user gets away with telling me to "improve performance of a table". I do not take such input kindly. I do not tell a user or manager how they must perform their duties. I expect the same courtesy from them. Tell me the problem and I will do my best to create an optimal technical solution for it. But an and end-user, don't be so arrogant to tell me what technical solution to implement. -
Hello Everybody ,
iam having interview for bi/bw support consultant and interview specs consists of data management techniques,improving and maintaining sap bi monitoring capabilities.solutions to support issues and understanding of BCC SAP solution and how its bw/bi configuration support the business.knowledge of wad.please send me the expected questions and answers though iam searching sdn using specs.
Regards
PriyaHi priya
Here are some Q&A.
Normally the production support activities include
Scheduling
R/3 Job Monitoring
B/W Job Monitoring
Taking corrective action for failed data loads.
Working on some tickets with small changes in reports or in AWB objects.
The activities in a typical Production Support would be as follows:
1. Data Loading - could be using process chains or manual loads.
2. Resolving urgent user issues - helpline activities
3. Modifying BW reports as per the need of the user.
4. Creating aggregates in Prod system
5. Regression testing when version/patch upgrade is done.
6. Creating adhoc hierarchies.
we can perform the daily activities in Production
1. Monitoring Data load failures thru RSMO
2. Monitoring Process Chains Daily/weekly/monthly
3. Perform Change run Hierarchy
4. Check Aggr's Rollup
To add to the above
1)check data targets are ready for reporting,
2) No failed or cancelled jobs in sm37 monitors and Bw Monitor.
3) All requests are loaded for day, monthly and yearly also.
4) Also to note down time taken for loading of critical info cubes which are used for reporting.
5) Is there any break in any schedules from your process chains.
As the frequent failures and errors , there is no fixed reason for the load to be fail , if you want it for the interview perspective I would answer it in this way.
a) Loads can be failed due to the invalid characters
b) Can be because of the deadlock in the system
c) Can be because of previous load failure , if the load is dependant on other loads
d) Can be because of erroneous records
e) Can be because of RFC connections
These are some of the reasons for the load failures.
Why there is frequent load failures during extractions? and how to analyse them?
If these failures are related to Data, there might be data inconsistency in source system. Though we are handling properly in transfer rules. We can monitor these issues in T-code -> RSMO and PSA (failed records) and update.
If we are talking about whole extraction process, there might be issues of work process scheduling and IDoc transfer to target system from source system. These issues can be re-initiated by canceling that specific data load and ( usually by changing Request color from Yellow - > Red in RSMO). and restart the extraction.
What is the daily task we do in production support.How many times we will extract the data at what times.
It depends... Data load timings are in the range of 30 mins to 8 hrs. This time is depends in number of records and kind of transfer rules you have provided. If transfer rules have some kind of round about transfer rules and updates rules has calculations for customized key figures... long times are expected..
Usually You need to work on RSMO and see what records are failing.. and update from PSA.
What are some of the frequent failures and errors?
As the frequent failures and errors , there is no fixed reason for the load to be fail , if you want it for the interview perspective I would answer it in this way.
a) Loads can be failed due to the invalid characters
b) Can be because of the deadlock in the system
c) Can be because of previous load failure , if the load is dependant on other loads
d) Can be because of erroneous records
e) Can be because of RFC connections
These are some of the reasons for the load failures.
for Rfc connections:
We use SM59 for creating RFC destinations
Some questions
1) RFC connection lost.
A) We can check out in the SM59 t-code
RFC Des
+ R/3 conn
CRD client (our r/3 client)
double click..test connection in menu
2) Invalid characters while loading.
A) Change them in the PSA & load them.
3) ALEREMOTE user is locked.
A) Ask your Basis team to release the user. It is mostly ALEREMOTE.
2) Password Changed
3) Number of incorrect attempts to login into ALEREMOTE.
4) USE SM12 t-code to find out are there any locks.
4) Lower case letters not allowed.
A) Uncheck the lower case letters check box under "general" tab in the info object.
5) While loading the data i am getting messeage that 'Record
the field mentioned in the errror message is not mapped to any infoboject in the transfer rule.
6) object locked.
A) It might be locked by some other process or a user. Also check for authorizations
7) "Non-updated Idocs found in Source System".
8) While loading master data, one of the datapackage has a red light error message:
Master data/text of characteristic ZCUSTSAL already deleted .
9) extraction job aborted in r3
A) It might have got cancelled due to running for more than the expected time, or may be cancelled by R/3 users if it is hampering the performance.
10) request couldnt be activated because there is another request in the psa with a smaller sid
A)
11) repeat of last delta not possible
12) datasource not replicated
A) Replicate the datasource from R/3 through source system in the AWB & assign it to the infosource and activate it again.
13) datasource/transfer structure not active.
A) Use the function module RS_TRANSTRU_ACTIVATE_ALL to activate it
14) ODS activation error.
A) ODS activation errors can occur mainly due to following reasons-
1.Invalid characters (# like characters)
2.Invalid data values for units/currencies etc
3.Invalid values for data types of char & key figures.
4.Error in generating SID values for some data.
15. conversio routine error
solution.check the data format in source
16.OBJECT CANOOT BE ACTIVATED.or error when activating object
check the consistency of the object.
17.no data found.(in query)
check the info provider wether data is there or not and delete unsucessful request.
18.error generating or activating update rules.

LIS, FI-SL, CO-PA
Cross Application (Generic Extractors)
o DB View, InfoSet, Function Module
2. What are the steps involved in LO Extraction?

o RSA5 Select the DataSources
o LBWE Maintain DataSources and Activate Extract Structures
o LBWG Delete Setup Tables
o 0LI*BW Setup tables
o RSA3 Check extraction and the data in Setup tables
o LBWQ Check the extraction queue
o LBWF Log for LO Extract Structures
o RSA7 BW Delta Queue Monitor
3. How to create a connection with LIS InfoStructures?
LBW0 Connecting LIS InfoStructures to BW
4. What is the difference between ODS and InfoCube and MultiProvider?
ODS: Provides granular data, allows overwrite and data is in transparent tables, ideal for drilldown and RRI.
CUBE: Follows the star schema, we can only append data, ideal for primary reporting.
MultiProvider: Does not have physical data. It allows to access data from different InfoProviders (Cube, ODS, InfoObject). It is also preferred for reporting.
5. What are Start routines, Transfer routines and Update routines?
Start Routines: The start routine is run for each DataPackage after the data has been written to the PSA and before the transfer rules have been executed. It allows complex computations for a key figure or a characteristic. It has no return value. Its purpose is to execute preliminary calculations and to store them in global DataStructures. This structure or table can be accessed in the other routines. The entire DataPackage in the transfer structure format is used as a parameter for the routine.
Transfer / Update Routines: They are defined at the InfoObject level. It is like the Start Routine. It is independent of the DataSource. We can use this to define Global Data and Global Checks.
6. What is the difference between start routine and update routine, when, how and why are they called?
Start routine can be used to access InfoPackage while update routines are used while updating the Data Targets.
7. What is the table that is used in start routines?
Always the table structure will be the structure of an ODS or InfoCube. For example if it is an ODS then active table structure will be the table.
8. Explain how you used Start routines in your project?
Start routines are used for mass processing of records. In start routine all the records of DataPackage is available for processing. So we can process all these records together in start routine. In one of scenario, we wanted to apply size % to the forecast data. For example if material M1 is forecasted to say 100 in May. Then after applying size %(Small 20%, Medium 40%, Large 20%, Extra Large 20%), we wanted to have 4 records against one single record that is coming in the info package. This is achieved in start routine.
9. What are Return Tables?
When we want to return multiple records, instead of single value, we use the return table in the Update Routine. Example: If we have total telephone expense for a Cost Center, using a return table we can get expense per employee.
10. How do start routine and return table synchronize with each other?
Return table is used to return the Value following the execution of start routine
11. What is the difference between V1, V2 and V3 updates?
V1 Update: It is a Synchronous update. Here the Statistics update is carried out at the same time as the document update (in the application tables).
V2 Update: It is an Asynchronous update. Statistics update and the Document update take place as different tasks.
o V1 & V2 dont need scheduling.
Serialized V3 Update: The V3 collective update must be scheduled as a job (via LBWE). Here, document data is collected in the order it was created and transferred into the BW as a batch job. The transfer sequence may not be the same as the order in which the data was created in all scenarios. V3 update only processes the update data that is successfully processed with the V2 update.
12. What is compression?
It is a process used to delete the Request IDs and this saves space.
13. What is Rollup?
This is used to load new DataPackages (requests) into the InfoCube aggregates. If we have not performed a rollup then the new InfoCube data will not be available while reporting on the aggregate.
14. What is table partitioning and what are the benefits of partitioning in an InfoCube?
It is the method of dividing a table which would enable a quick reference. SAP uses fact file partitioning to improve performance. We can partition only at 0CALMONTH or 0FISCPER. Table partitioning helps to run the report faster as data is stored in the relevant partitions. Also table maintenance becomes easier. Oracle, Informix, IBM DB2/390 supports table partitioning while SAP DB, Microsoft SQL Server, IBM DB2/400 do not support table portioning.
15. How many extra partitions are created and why?
Two partitions are created for date before the begin date and after the end date.
16. What are the options available in transfer rule?
InfoObject
Constant
Routine
Formula
17. How would you optimize the dimensions?
We should define as many dimensions as possible and we have to take care that no single dimension crosses more than 20% of the fact table size.
18. What are Conversion Routines for units and currencies in the update rule?
Using this option we can write ABAP code for Units / Currencies conversion. If we enable this flag then unit of Key Figure appears in the ABAP code as an additional parameter. For example, we can convert units in Pounds to Kilos.
19. Can an InfoObject be an InfoProvider, how and why?
Yes, when we want to report on Characteristics or Master Data. We have to right click on the InfoArea and select Insert characteristic as data target. For example, we can make 0CUSTOMER as an InfoProvider and report on it.
20. What is Open Hub Service?
The Open Hub Service enables us to distribute data from an SAP BW system into external Data Marts, analytical applications, and other applications. We can ensure controlled distribution using several systems. The central object for exporting data is the InfoSpoke. We can define the source and the target object for the data. BW becomes a hub of an enterprise data warehouse. The distribution of data becomes clear through central monitoring from the distribution status in the BW system.
21. How do you transform Open Hub Data?
Using BADI we can transform Open Hub Data according to the destination requirement.
22. What is ODS?
Operational DataSource is used for detailed storage of data. We can overwrite data in the ODS. The data is stored in transparent tables.
23. What are BW Statistics and what is its use?
They are group of Business Content InfoCubes which are used to measure performance for Query and Load Monitoring. It also shows the usage of aggregates, OLAP and Warehouse management.
24. What are the steps to extract data from R/3?
Replicate DataSources
Assign InfoSources
Maintain Communication Structure and Transfer rules
Create and InfoPackage
Load Data
25. What are the delta options available when you load from flat file?
The 3 options for Delta Management with Flat Files:
o Full Upload
o New Status for Changed records (ODS Object only)
o Additive Delta (ODS Object & InfoCube)
SAP BW Interview Questions 2
1) What is process chain? How many types are there? How many we use in real time scenario? Can we define interdependent processes with tasks like data loading, cube compression, index maintenance, master data & ods activation in the best possible performance & data integrity.
2) What is data integrityand how can we achieve this?
3) What is index maintenance and what is the purpose to use this in real time?
4) When and why use infocube compression in real time?
5) What is mean by data modelling and what will the consultant do in data modelling?
6) How can enhance business content and what for purpose we enhance business content (becausing we can activate business content)
7) What is fine-tuning and how many types are there and what for purpose we done tuning in real time. tuning can only be done for infocube partitions and creating aggregates or any other?
8) What is mean by multiprovider and what purpose we use multiprovider?
9) What is scheduled and monitored data loads and for what purpose?
Ans # 1:
Process chains exists in Admin Work Bench. Using these we can automate ETTL processes. These allows BW guys to schedule all activities and monitor (T Code: RSPC).
PROCESS CHAIN - Before defining PROCESS CHAIN, let us define PROCESS in any given process chain. Is a procedure either with in the SAP or external to it with a start and end. This process runs in the background.
PROCESS CHAIN is set of such processes that are linked together in a chain. In other words each process is dependent on the previous process and dependencies are clearly defined in the process chain.
This is normally done in order to automate a job or task that has to execute more than one process in order to complete the job or task.
1. Check the Source System for that particular PC.
2. Select the request ID (it will be in Header Tab) of PC
3. Go to SM37 of Source System.
4. Double Click on the Job.
5. You will navigate to a screen
6. In that Click "Job Details" button
7. A small Pop-up Window comes
8. In the Pop-up screen, take a note of
a) Executing Server
b) WP Number/PID
9. Open a new SM37 (/OSM37) command
10. In the Click on "Application Servers" button
11. You can see different Application Servers.
11. Goto Executing server, and Double Click (Point 8 (a))
12. Goto PID (Point 8 (b))
13. On the left most you can see a check box
14. "Check" the check Box
15. On the Menu Bar.. You can see "Process"
16. In the "process" you have the Option "Cancel with Core"
17. Click on that option. * -- Ramkumar K
Ans # 2:
Data Integrity is about eliminating duplicate entries in the database and achieve normalization.
Ans # 4:
InfoCube compression creates new cube by eliminating duplicates. Compressed infocubes require less storage space and are faster for retrieval of information. Here the catch is .. Once you compress, you can't alter the InfoCube. You are safe as long as you don't have any error in modeling.
This compression can be done through Process Chain and also manually.

Ans#3
Indexing is a process where the data is stored by indexing it. Eg: A phone book... When we write somebodys number we write it as Prasads number would be in "P" and Rajesh's number would be in "R"... The phone book process is indexing.. similarly the storing of data by creating indexes is called indexing.
Ans#5
Datamodeling is a process where you collect the facts..the attributes associated to facts.. navigation atributes etc.. and after you collect all these you need to decide which one you ill be using. This process of collection is done by interviewing the end users, the power users, the share holders etc.. it is generally done by the Team Lead, Project Manager or sometimes a Sr. Consultant (4-5 yrs of exp) So if you are new you dont have to worry about it....But do remember that it is a imp aspect of any datawarehousing soln.. so make sure that you have read datamodeling before attending any interview or even starting to work....
Ans#6
We can enhance the Business Content bby adding fields to it. Since BC is delivered by SAP Inc it may not contain all the infoobjects, infocubes etc that you want to use according to your company's data model... eg: you have a customer infocube(In BC) but your company uses a attribute for say..apt number... then instead of constructing the whole infocube you can add the above field to the existing BC infocube and get going...
Ans#7
Tuning is the most imp process in BW..Tuning is done the increase efficiency.... that means lowering time for loading data in cube.. lowering time for accessing a query.. lowering time for doing a drill down etc.. fine tuning=lowering time(for everything possible)...tuning can be done by many things not only by partitions and aggregates there are various things you can do... for eg: compression, etc..
Ans#8
Multiprovider can combine various infoproviders for reporting purposes.. like you can combine 4-5 infocubes or 2-3 infocubes and 2-3 ODS or IC, ODS and Master data.. etc.. you can refer to help.sap.com for more info...
Ans#9
Scheduled data load means you have scheduled the loading of data for some particular date and time you can do it in scheduler tab if infoobject... and monitored means you are monitoring that particular data load or some other loads by using transaction RSMON.
1.Procedure for repeat delta?
You need to make the request status to Red in monitor screen and then delete it from ODS/Cube. Then when you open infopackage again, system will prompt you for repeat delta.
also.....
Goto RSA7->F2->Update Mode--->Delta Repetation
Delta repeation is done based on type of upload you are carrying on.
1. if you are loading masterdata then most of the time you will change the QM status to red and then repeat the delta for the repeat of delta. the delta is allowed only if you make the changes.
and some times you need to do the RnD if the repeat of delta is not allowed even after the qm status id made to red. here you have to change the QM status to red.
If this is not the case, the source system and therefore also the extractor, have not yet received any information regarding the last delta and you must set the request to GREEN in the monitor using a QM action.
The system then requests a delta again since the last delta request has not yet occurred for the extractor.
Afterwards, you must reset the old request that you previously set to GREEN to RED since it was incorrect and it would otherwise be requested as a data target by an ODS.
Caution: If the termianted request was a REPEAT request itself, always set this to RED so that the system tries to carry out a repeat again.
To determine whether a delta or a repeat are to be requested, the system ONLY uses the status of the monitor.
It is irrelevant whether the request is updated in a data target somewhere.
When activating requests in an ODS, the system checks delta repeat requests for completeness and the correct sequence.
Each green delta/repeat request in the monitor that came from the same DataSource/source system combination must be updated in the ODS before activation, which means that in this case, you must set them back to RED in the monitor using a QM action when using the solution described above.
If the source of the data is a DataMart, it is not just the DELTARNR field that is relevant (in the roosprmsc table in the system in which the source DataMart is, which is usually your BW system since it is a Myself extraction in this case), rather the status of the request tabstrip control is relevant as well.
Therefore, after the last delta request has terminated, go to the administration of your data source and check whether the DataMart indicator is set for the request that you wanted to update last.
If this is NOT the case, you must NOT request a repeat since the system would also retransfer the data of the last delta but one.
This means, you must NOT start a delta InfoPackage which then would request a repeat because the monitor is still RED. For information about how to correct this problem, refer to the following section.
For more information about this, see also Note 873401.
Proceed as follows:
Delete the rest of this request from ALL updated data targets, set the terminated request to GREEN IN THE MONITOR and request a new DELTA.
Only if the DataMart indicator is set does the system carry out a repeat correctly and transfers only this data again.
This means, that only in this case can you leave the monitor status as it is and restart the delta InfoPackage. Then this creates a repeat request
In addition, you can generally also reset the DATAMART indicator and then work using a delta request after you have set the incorrect request to GREEN in the monitor.
Simply start the delta InfoPackage after you have reset the DATAMART indicator AND after you have set the last request that was terminated to GREEN in the monitor.
After the delta request has been carried out successfully, remember to reset the old incorrect request to RED since otherwise the problems mentioned above will occur when you activate the data in a target ODS.
What is process chain and how you used it?
A) Process chains are tool available in BW for Automation of upload of master data and transaction data while taking care of dependency between each processes.
B) In one of our scenario we wanted to upload wholesale price infoobject which will have wholesale price for all the material. Then we wanted to load transaction data. While loading transaction data to populate wholesale price, there was a look up in the update rule on this InfoObject masterdata table. This dependency of first uploading masterdata and then uploading transaction data was done through the process chain.
What is process chain and how you used it?
A) We have used process chains to automate the delta loading process. Once you are finished with your design and testing you can automate the processes listed in RSPC. I have a real time example in the attachment.
1. What is process chain and how you used it?
Process chains are tool available in BW for Automation of upload of master data and transaction data while taking care of dependency between each processes.
2. What is transaction for creating Process Chains ?
RSPC .
3. Explain Colector Process ?
Collector processes are used to manage multiple predecessor
processes that feed into the same subsequent process. The collector
processes available for BW are:
AND :
All of the direct predecessor processes must raise an event in order for subsequent processes to be executed
OR :
A least one predecessor process must send an event The first predecessor process that sends an event triggers the subsequent process
Any additional predecessor processes that send an event will again trigger
subsequent process (Only if the chain is planned as periodic)
EXOR : Exclusive OR
Similar to regular OR, but there is only ONE execution of the successor
processes, even if several predecessor processes raise an event
4. What are application Process ?
Application processes represent BW activities that are typically
performed as part of BW operations.
Examples include:
Data load
Attribute/Hierarchy Change run
Aggregate rollup
Reporting Agent Settings
5. Tell some facts about process Chains
Process chains are transportable Button for writing to a change request when
maintaining a process chain in RSPC
Process chains available in the transport connection wizard (administrator workbench)
If a process dumps, it is treated in the same manner as a failed process
Graphical display of Process Chain Maintenance requires the 620 SAPGUI and SAP BW 3.0B Frontend GUI
A special control background job runs to facilitate the execution of the of the other batch jobs of the process chain
Note your BTC process distribution, and make sure that an extra BTC process is available so the supporting control job can run immediately
6. What happens when chain is activated ?
When a chain gets activated It will be copied into active version The processes will be planned in batch as program RSPROCESS with type and variant given as parameters with job name BI_PROCESS_<TYPE> waiting for event, except the trigger The trigger is planned as specified in its variant, if start via meta-chain it is not planned to batch
7. Steps in process chains ?
Go to transaction code-> RSPC
Follow the Basic Flow of Process chain..
1. Start chain
2. Delete BasicCube indexes
3. Load data from the source system into the PSA
4. Load data from the PSA into the ODS object
5. Activate data in the ODS object
6. Load data from the ODS object in the BasicCube
7. Create indexes after loading for the BasicCube
