Modifying Object type

Hi
How do I modify object type without droping table containing that object?
Thanks a lot

You haven't given a great deal of information about which version of Oracle you're talking about.
However the simple answer is if it's not version 9i then you're going to have huge problems with object evolution, no version prior to 9i has allowed you to easily modify an object and maintain any data in associated object tables (there ARE horrendous workarounds but if you can move to 9i it WILL save you a tremendous amount of headaches/hacks).

Help! modifying size of varchar2 in object-type

Hi,
Does anybody know a way to increase the size of a varchar2 attribute in an ORACLE object type without having to drop all object tables created from this type? I'm working on a ORACLE 8i (8.1.6) version and there are several millions of records stored in that table, and all I need to do is modify a varchar2(35) to varchar2(100).

This command don't work ?

Partitioned IOT of Object Type - mapping table not allowed for bitmap index

Hi,
looks like a feature available for standard Partitioned IOTs is not supported for object based tables, namely the MAPPING TABLE construct to support secondary local bitmap indexes.
Can you confirm behaviour is as expected/documented?
If so, is a fix/enhancement to support mapping table for object-based Partitioned IOTs in the pipeline?
Results for partition-wise load using pipelined table function are very good, look-ups across tens of millions of rows are excellent.

Thanks Dan,
the intention is to range partition based on the initial character, so A* -> Text_Part_A, B* -> Text_Part_B, and so on.
Here's an example, using an empty IOTObj_Table as created previously.
1) Set up & confirm some test data (two 'D's, one 'N', and two 'Z's)
SQL> INSERT INTO IOTObj_Table VALUES (IOT_Type('DEF456',500));
SQL> INSERT INTO IOTObj_Table VALUES (IOT_Type('DDD111',510));
SQL> INSERT INTO IOTObj_Table VALUES (IOT_Type('N3000',515));
SQL> INSERT INTO IOTObj_Table VALUES (IOT_Type('ZZ1212',520));
SQL> INSERT INTO IOTObj_Table VALUES (IOT_Type('Z111X',530));
SQL> COMMIT;
SQL> SELECT * FROM IOTObj_Table;

DEF456     500
N3000     515
Z111X     530
ZZ1212     520
2) Just to prove our IOT is enforcing the Primary Key based on the TextData attribute, try to insert a duplicate
SQL> INSERT INTO IOTObj_Table VALUES (IOT_Type('Z111X',530));
Error starting at line 141 in command:
INSERT INTO IOTObj_Table VALUES (IOT_Type('Z111X',530))
Error report:

*Cause:    An UPDATE or INSERT statement attempted to insert a duplicate key.
For Trusted Oracle configured in DBMS MAC mode, you may see
this message if a duplicate entry exists at a different level.
*Action:   Either remove the unique restriction or do not insert the key.
3) Now confirm that our data has been slotted into the range-based partition we expect using the PARTITION clause of SELECT...
- The two 'D's...
SQL> SELECT * FROM IOTObj_Table PARTITION (Text_Part_D);
TEXTDATA NUMBERDATA
DDD111     510
DEF456     500
- The single 'N'...
SQL> SELECT * FROM IOTObj_Table PARTITION (Text_Part_N);

SQL> SELECT * FROM IOTObj_Table PARTITION (Text_Part_Z);
TEXTDATA NUMBERDATA

4) And to wrap up confirm an empty partition

Schema of a new Object Type: message pass the BIU without validation

Hi,
i've defined a new Object Type for send messages to Web Service. I've created the schema files and i've uploaded there in repository with the "Import" function of GUI. After, i've defined the XML file for the "Execute" function of the B1i GUI.
After the load of files, in the repository the files are in correct position.
In my BIU the definition of sender and receiver system type is correct, and also the definition of SenderMainObjectTypeID and ReceiverObjectTypeID. The message from B1 pass through the IPO chain without problems and the message is received by teh Web Service.
If modify the file XSL into the BIU, a message with less elements than a schema pass without problem.
If delete the schema from repository, the message pass without validation.
I would know because the schema is bypassed...
Thans

Ok,
solved with introduction of validation point in a customized IPO using a branch / unbranch atoms.
Bye.

ObjectOutputStream: Sending the same but modified Object twice

Using the Windows JRE1.6_05 or the JRE 1.6 on Mac OS X and the following code for the client:
import java.io.ObjectInputStream;
import java.io.ObjectOutputStream;
import java.net.Socket;
public class Client {
     public static void main(String[] args) throws Exception {
          Socket s=new Socket("127.0.0.1",5000);
          ObjectOutputStream oos= new ObjectOutputStream(s.getOutputStream());
          StringBuffer sb=new StringBuffer("foo");
          oos.writeObject(sb);
          sb.replace(0, sb.length(), "bar");
          oos.writeObject(sb);
}and the following code for the server
import java.io.ObjectInputStream;
import java.io.ObjectOutputStream;
import java.net.ServerSocket;
import java.net.Socket;
public class Server {
     public static void main(String[] args) throws Exception {
          ServerSocket ss=new ServerSocket(5000);
          Socket s= ss.accept();
          ObjectInputStream ois= new ObjectInputStream(s.getInputStream());
          StringBuffer sb=(StringBuffer)ois.readObject();
          System.out.print(sb);
          sb=(StringBuffer)ois.readObject();
          System.out.println(" "+sb);
}I expect to get the output "foo bar" but getting "foo foo". For every object type it is true that the non-modified object is received, if the same but modified object is sent twice. Is this a bug?

The requirement is there i want to define method, that should display the po release screen. If i bind this method with work flow template, mail should be triggered and if i click the mail po release screen should be opened for respective material...

Delete Business Object Type (SWO1)

Hi gurus,
How can we delete/modify objects in SWO1 that were created in a previous version. Are these actions allowed, is there a workaround if its not allowed?
Thanks for your help!
Jason

Hi Raymond,
Thank you for your help.
I have come accross that thread in SDN while doing some research already. But It does not completely answer my question.
Correct me if I'm wrong, this means there is absolutely no workaround to modify a business object type that has been created in a different version? If thats the case why does SAP enforce this rule?
Thank you

Error in modifying Object Value in Triggers defined on Object Tables

Hi,
While practising with Triggers, the following error was encountered. Could anyone suggest what is the reason and solution for the problem.
An Object Type and an object Table are created.
create or replace
type typPerson is object
(id number,
firstname varchar2(30),
lastname varchar2(30)
create table person_obj_tab of typPerson
/Below is the trigger that modifies data according to some scenario.
Create Or Replace Trigger Trg_B_Iou_POT
before insert or update on person_obj_tab
for each row
begin
:new.object_value:= typperson(15,'Object1','Changed') ;
end;
/Trigger created.
I executed the below insert statement, and I got the following error.
SQL> insert into person_obj_tab values (10,'Object1','From Trigger');
insert into person_obj_tab values (10,'Object1','From Trigger')
ERROR at line 1:

SQL> select 1 from dual;
ERROR:

Create Or Replace Trigger Trg_B_Iou_POT

:new.id:= 15;
:new.firstname := 'Object1' ;
:new.lastname := 'Changed';
end;
SQL> insert into person_obj_tab values (10,'Object','Original');
1 row created.
Question:
1) Trigger of version 1 did not report any error during compilation, but during DML execution, hangs for sometime and gives the above error.
2) Whether direct assignment of Objects of greater size is possible inside triggers built on object Tables?
3) Suppose an object contain multiple attributes (say more than 20), then how to assign them inside a trigger?
Thanks,
Sudher

Hi Sudher,
I have at least one possible reason for this behaviour.
The pseudo-column object_value returns system-generated names for the columns of an object table.
I don't know if you can use it for a complete instance you want to modify.
And I recognized that you don't use the constructor for inserting data in your table.
Why not?
Following suggestion:
create or replace
type typPerson is object
(id number,
firstname varchar2(30),
lastname varchar2(30)
create table person_obj_tab of typPerson
Create Or Replace Trigger Trg_B_Iou_POT
before insert or update on person_obj_tab
for each row
begin
:new.id := 15;
:new.firstname := 'Object1';
:new.lastname := 'Changed';
end;
insert into person_obj_tab values (typperson(10,'Object1','From Trigger'));
select * from person_obj_tab;When you modify the attributes always for themselves, it works.
Triggers in my opinion have the issue to modify or set some choosen columns, but not all.

Domains for Oracle object types

When I create a domain for a certain Oracle object type there is no way to create some kind of inheritance tree (and there is no discriminator support it seems). On the database level I have several object types that extend a certain base object type. I want to do the same at the BC4J level. But unfortunately this doesn't seem possible. Is there a work-around for it? I don't mind to write a little extra code, any hints or help are appreciated.
Regards,
Peter
P.S.
It seems the object type / domain support in JDeveloper 9.0.3(.1) isn't quite up there with entities and view objects. It's not even possible to change an attribute name at the Java side using the domain dialog (it's only possible by manually editing the XML and Java files). Will JDeveloper 9.0.4 have broader support for object types / domains?

I've found a way to implement the inheritance myself, at least a start. I've noticed all custom domains for oracle object types have the static method "getCustomerDatumFactory". In this method (in the base domain class) normally an instance of the base type is returned. I've modified this method so that it returns instances of the different subtypes depending on the value of a certain column. To make this work I first have to edit the Java files of the subtypes and let them extend the base type instead of the Struct class. The factory method looks like this:
public static CustomDatumFactory getCustomDatumFactory()
    if (fac == null)
      class facClass implements CustomDatumFactory
        public CustomDatum create(Datum d, int sql_type_code) throws SQLException
          if (d != null)
            BaseType b = new BaseType(d);
            if ("subtype1".equals(b.getType())) b = new SubType1(d);
            else if ("subtype2".equals(p.getType())) b = new SubType2(d);
            else System.err.println("Unknown subtype: " + b.getType());
            return b;
          return null;
      fac = new facClass();
    return fac;
}I also tried to save several of the subtypes in the database in the attribute field (which is of the base type) using setAttribute, this seems to work out-of-the-box. It seems for now I only get this to work if the object type is saved in a column of a certain table, I can't get it to work (yet) for object type tables (see the other recent topic of mine).
Is this the correct way to implement what I want? Or is there a better way?
Regards,
Peter

How can I add that ? Thank you

Hi The SAP Query comprises five components:
      Queries
      InfoSet Query
      InfoSets
      User Groups
      Translation/Query
Classic reporting- the creation of lists, statistics and ranked lists- are covered by the InfoSet Query and Queries components. Other componentsu2019 range of functions cover the maintenance of InfoSets, the administration of user groups and also the translation of texts created in the SAP Query. All data required by a user for a report can be read from various tables.
To define a report, you first have to enter individual texts, such as titles, and select the fields and options, which determine the report layout. In the WYSIWYG (What You See Is What You Get) mode, you can edit the lists using Drag & Drop and various toolbars.
Overview:
The following sections describes the individual SAP Query components and provides general information about query areas, transport and authorizations
Menu Path     Used For     Transaction Code
à SAP Query à Queries     Maintaining Queries     SQ01
à SAP Query à InfoSets     Maintaining InfoSets     SQ02
à SAP Query à User Groups     Maintaining User Groups     SQ03
à Translation à Query     Language Comparision     SQ07
Query Components
The Queries component is used by end users to maintain queries.
You can carry out the following tasks:
      Execute Queries and Generate Lists
      Define Queries
      Change Queries
Infosets Components
      InfoSets are special views of data sources.
      An InfoSet describes which fields of a data source can be reported on in queries.
      InfoSets are assigned to user groups.
      End-users are able to work only with those InfoSets that are relevant to their particular area, as designated by the role or user group that they are assigned to.
      Eg: Vendor master data can be important in purchasing as well as in accountancy. The relevant InfoSet is assigned to both roles/user groups. This means that queries based on this InfoSet can be copied and executed by both groups.
User Groups Components
1.     The User Groups component is used to maintain user groups. The system administrator uses it to set up the work environment for end-users.
2.     Every user assigned to the user group is able to execute the query.
3.     Users are not allowed to modify queries from other user groups, although they may, under certain circumstances, copy and execute
Translation/Query Component
      A great deal of text is generated when defining queries, InfoSets, and user groups.
      The SAP Query displays these texts in the language that you chose when you logged on to the SAP system.
      You can compare the text languages using the component Translation/Query.
      A related text in one or more additional languages is made available for each of the texts created when defining the query.
Query Areas
A query area contains a set of query objects (queries, InfoSets, and user groups) that are discrete and consistent.
There are the following query areas:
      Standard area
      Global area
Standard Area
1.Client specific
2.Query objects are not attached to the Workbench Organizer
Advantage :-End users can develop queries (ad-hoc reports) in their own client that are not meant for use in the rest of the system.
Global Area
1.Cross client
2.Query objects are attached to workbench organizer
Advantage:-The global query area is well suited for centrally developing queries meant for use and distribution throughout the system.
Authorizations
End-users, system administrators, and translators must all be assigned the appropriate authorizations allowing them to work with the SAP Query.
In order to give individual users targeted, specific rights, the following options are available:
      Roles/user groups
      Authorizations
Steps to create a Query
Step     Description     TCODE
1     Create a infoset or functional area     SQ02
2     Assignment of user group to infoset     SQ03
3     Creation of query based on infoset     SQ01
Tools for Queries
The following are the tools to manage, create and change queries.
      Infoset Query
      Queries
      Quick viewer
SAP Query
Step-by-step procedure in configuring SAP Query
SAP R/3 Query tools (SAP Query) are based on the following four main components:
u2022     Query Areas
u2022     Query Groups
u2022     InfoSets
u2022      Administrative Decisions (Company-specific)
Configuration of the Query tools is done in the following manner:
u2022     Create Query Groups
u2022      Assign Users to Query Groups
u2022     Create InfoSets
u2022      Assign each InfoSet to a Query Group.
Create Query Groups
u2022        Go to Transaction SQ03.
u2022        Ensure that you are in the correct SAP Query area by navigating to Environment à Query Areas
u2022        Select the u201CStandard Area (Client-specific).
u2022        Now in the main screen, enter the name of the Query Group in the User Group field and click on CREATE
u2022        Enter the description of the User Group in the next popup that appears.
u2022        User Group ZSAPTECH_GRP is created.
Assign Users to Query Groups
u2022        Click on the u201CAssign Users and InfoSetsu201D button
u2022        Enter the SAP User-Ids of all the users you wish to include in the test group.
Click on SAVE to save your entries.

Create object type from multiple tables for select statement

Hi there,
I have 3 tables as given below and I wish to create an object type to group selected columns as 'attribute' from multiple tables.
I need to create 2 input parameters to pass in - 'attribute' and 'attribute value' in PL/SQL and these 2 parameters will be
passing in with 'column name' and 'column value'. e.g. 'configuration' - the column name, 'eval' - the column value.
Then, the PL/SQL will execute the select statement with the column and column value provided to output the record.
Pls advise and thank you.

Reason to do this as these fields are required to be grouped together as they are created in different tables. They are treated as 'attribute' (consists of many columns) of the part number. So, the PL/SQL is requested to design in a way able for user to pass in the column name and column value or part number, then the select statement should be able to query for the records. Another reason is a new column can be added easily without keep modifying those effected programs. Reuseable too.This basically equates to ... hard to code, hard to maintain, and poor performance.
Are you really sure you want to do this? This isn't going to be easy-street as you seem to think it is, but it's a one way street to a poorly performing system with security vulnerabilities (google SQL Injection).
I would highly recommend you reconsider your design decision here.

Increased Object Type support within Data Modeler

Hi,
This is a question mainly for the Data Modeler Development Team as well as the Tools group. First of all, the production version of Data Modeler 3.0 is very nice and the improvements in the DataTypes area over what was in EA1 are great. Thanks for adding the Domain support to the definition of Attributes and Parameters for Methods, that makes life much simpler and opens the door for a much wider range of object type modeling and ease of implementations since consistency can now be maintained much easier via Domains. Also the support for straightening of lines is awesome. This is the best implementation I have seen, even better that what we had in the Design Editor in Oracle Designer, kudos again to the team that built the diagrammer interfaces.
My question is, Going forward will Data Modeler continued to be enhanced to finally fully support Oracle Objects and the object relational (OR) model? I ask this because as users of Oracle's RDBMS, we do not have a tool that allows us to fully model and implement the features provided by the Server Group in the area of Object-Relational features and functionality. Oracle Designer had some OR modeling capability, but the end of life on product stopped all further development. One of the common excuses is there is no market demand for object - relational modeling. I would argue, that the lack of market demand for object - relational applications is because we have never have had a tool that fully supports Oracle's object - relational model. Nor do have we had a development tool that allows us to implement a fully developed Oracle Object - Relational model. The tools group stopped the development of Oracle Forms support for nested objects and collections. The LOV functionality for REF columns is pretty awesome, but we can't get to nested collections much less a nested collection of REFs.
So as a member of the end user community, we are stuck in this Catch 22. The Server Group continues to support and enhance the Object - Relational model, but the Tools and Modeling Groups haven't kept up with the tools to model or implement the functionality and features supported by the database. As a result we have a partially built set of tools that allows us to scratch the surface of the Object - Relational model but are not able to take full advantage of the powerful features of inheritance, inherited and extended collections, the ability to inherit and then extend methods, etc...
The Object - Relational model was introduced with Oracle8, 10g solved the type evolution problem which made production implementation of object types realistic. My question is; Is Data Modeler finally going to fully support Oracle's object - relational model? If we as the end user community finally get a tool that does fully support the OR model, we'll finally be able to model, build and deploy applications that will in turn create that market demand which is lacking for the object relational model.
Thanks in advance,
ScottK

Phil,
Yes, having the ability to include an attribute from an data type as part of the PK, UK and or index will be very, very nice. Doing that opens a number of doors on the design, modeling and implementation sides. It would allow us to model and then create a data type which has all the common attributes for housekeeping information within each entity -> table. This is something we tried to do with Designer but was pretty involved script wise. By being able to create specialized housekeeping datatypes and then using the 'add attribute' with the scripts provided with DM 3.0, it simplifies the model after the fact. Think about it, we'll be able to have a datatype with all the attributes for created on/by and modified on/by along will all the methods to populate those attributes (formerly columns), then we can include that datatype into the entity as an attribute called say, 'row_audit' with the datatype of 'common_'. Now in one pass we have the place to hold the information of who created and modified the row as well as the date and time along with all the code required to populate and maintain that information. Everything modeled, defined and written in one place. No more have to include or write the pl/sql across several different modules, rather the calls to the method, a constructor, are within the insert or update statements for that table. If we take that train of thought and extend it to include the housekeeping functions for relational primary keys, then we can create one datatype with the attribute and methods to create a single column primary key. Once that is pulled into an entity, defined as the part of the unique identifier and then pushed down as a primary key and resulting foreign keys. We have all the code to enforce and populate primary and foreign keys wrapped up in one datatype with its supporting method as a constructor. Think of the other possibilities that would be available once we can include nested attributes w/i keys and indexes. It makes some models and designs much simpler, more maintainable, more scalable (less code to execute), etc...
I have been thinking about this. I see ya'll have provided the options for IN, OUT, IN/OUT, COPY and NOCOPY as modifiers for the parameters on methods. We also have the option for COPY / NOCOPY in the constructor method for type. Will that be included?
Lastly, since the Server Group solved the type evolution problem, that coupled with the ability to include a datatype as a definition for column really opens the design doors. For example, by using a datatype of 'common_', as mentioned above, if the system requirement appears after the system is built for a the name of the source system to be included with the 'row_audit' information, we can modify the datatype 'common_' to include these new attributes and methods and then the ALTER TYPE syntax provided by the Server and Language groups to effectively extend all the tables to include this new system requirement. Till the Server group solved the type evolution problem, this wasn't possible and we had to write several 'alter table add column' scripts. This is all replaced with the ALTER TYPE... cascade data command now. Once DM 3.0 includes the ability to reference embedded attributes, design and modeling life will be great.
Thanks in advance,
ScottK

Need Objective Type Qns

http://www.techinterviews.com/?p=198
<b>Also, refer the following questions on ABAP :</b>
ABAP Interview Questions
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.
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

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.

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.
