View V/s Extract structure in generic data source!

Hi,
Is it mandatory that view and extract structure must contain same number of fields in generic extraction?
can we enhance the extract structure with a field which is not existing in view?
clarify me with exmaple
Thanks,
Ravi

Thanks Diego!
Actaully, the view which is used in the definition of the data source has four tables
namely AFRU,CRHD,AUFK and AFKO.
Join conditions are:
AFRU     MANDT     =     CRHD     MANDT
AFRU     ARBID     =     CRHD     OBJID
AFRU     MANDT     =     AUFK     MANDT
AFRU     AUFNR     =     AUFK     AUFNR
AFRU     MANDT     =     AFKO     MANDT
AFRU     AUFNR     =     AFKO     AUFNR
Now, i want to know from which table is the field AUFNR is mapped to BW info object!
As the field is in both tables AFRU and AUFK, i am confused of from which table the data is getting filled up to the BW info object!
I need to make a documentation of of each info object of how is it getting filled up and from which table?
Thanks,
Ravi

Extraction, Flat File, Generic Data Source, Delta Initialization

Extraction, Flat File, Generic Data Source, Delta Initialization
I have couple of questions regarding data extraction.
1.     If you have Data Source a Flat File e.g. Excel file I know that you have to create Data Source at BW side. How do you upload updates, by selecting Delta Update when executing next Data Load? Do you ever u201Cconvertu201D this Excel file into Application Tables to become SAP Source 
2.     Can you please give me example of situation where you had to create Generic Data Source? What is difference between Time Stamp, Calend. Day and Numeric Pointer. Which one is most common to select?
3.     I read somewhere that Generic Data Source does not have Setup Table. I thought that you have to have Setup Table in order to load transaction Data otherwise you will lock the Application Tables. Where am I going wrong im my thinking please?
4.     What are steps in terms of IP before, under and after Delta Initialization. I belive that you can do two ways:
Full Update - Initialize Delta Process (without Data Transfer) u2013 Delta Update or
Initialize Delta Process (with Data Transfer) u2013 Delta Update
Am I right? What is most common method and why?
5.     If you want to add a filed in Data Source after 6 month using it, you want to do it without re-init Delta Queue. You add field in RSA6, then provide info for ABAP to populate new filed (info u2013 name of Data Source, Extract Structure, field added, name of Application Table which contains the field). How does it work now as there is no SetUp table it has been deleted after Initialisation? How does Delta Queue know that it is going to receive data which has been expanded by one field or it may does not need to know at all?
THANKSSSSSSSSSs

Hi,
1. If you have Data Source a Flat File e.g. Excel file I know that you have to create Data Source at BW side. How do you upload updates, by selecting Delta Update when executing next Data Load? Do you ever u201Cconvertu201D this Excel file into Application Tables to become SAP Source
Once you create Datasource for A flat file extraction then it is file source system specific hence you cont change to Application table source Data source
In info package you can change the source as application server instead of desktop no need to change the DS
2. Can you please give me example of situation where you had to create Generic Data Source? What is difference between Time Stamp, Calend. Day and Numeric Pointer. Which one is most common to select?
When we don't find any standard extractor then we can go for Generic(if i want information sales along with finance information in a data source then generally we dont get standard one hence we can go for generic DS)
Check the below link for More about generic DS .
http://wiki.sdn.sap.com/wiki/display/BI/Generic+Extraction
for Delta capturing you can use
Timestamp(if the table has time stamp filed so it can stamp the last changed record in that table hence it is easy to get delta based on the time stamp)
Calday- (If the table doesn't have the Timestamp filed then search for Calday where you can stamp the delta based on the date when documents are changed )
Numericpointer : If the table doesn't above both then we go for this option where you can the numeric value change stamp )
3. I read somewhere that Generic Data Source does not have Setup Table. I thought that you have to have Setup Table in order to load transaction Data otherwise you will lock the Application Tables. Where am I going wrong im my thinking please?
Generic datasource nothing but we extracting data directly from the database table without any interface between the application/systems
4. What are steps in terms of IP before, under and after Delta Initialization. I belive that you can do two ways:
Full Update - Initialize Delta Process (without Data Transfer) u2013 Delta Update or
Initialize Delta Process (with Data Transfer) u2013 Delta Update
Am I right? What is most common method and why?
Correct
5. If you want to add a filed in Data Source after 6 month using it, you want to do it without re-init Delta Queue. You add field in RSA6, then provide info for ABAP to populate new filed (info u2013 name of Data Source, Extract Structure, field added, name of Application Table which contains the field). How does it work now as there is no SetUp table it has been deleted after Initialisation? How does Delta Queue know that it is going to receive data which has been expanded by one field or it may does not need to know at all?
Once you add the new field to structure(DS) you will get the data as on date onwards not historical data hence what is the concept of setup table ( delta records come from the Delta Que not from the setup table )
If you want histaric data to new field then you need to setp table deletion ...etc...
Hope it is clear..

Generic Data Source with View

Hi Experts.....
previously i am creating one view based on VBRP & VBRK common field is VBELN but i have some confusion long days, these two tables having same data Source i.e..2LIS_13_VDHDR , why u create View. So please explain one real time sinario.

Hi,
When we don't find any standard extractor then we can go for Generic(if i want information sales along with finance information in a data source then generally we dont get standard one hence we can go for generic DS)
Re: Extraction, Flat File, Generic Data Source, Delta Initialization
Eg : If you want the information about the All Customers across the regions in that case if i have the information
Like 1)Table 1 has all the information about the Customer number But not having the Customer address and region and Pin code but same information has in other table
table 2 : Customer no,Address, region and Pincode
So since in Two tables i have common field Customer no is present hence if create view then i can get All the information in single in view then you can create Generic DS based on the then same you ca extract the data to BW.

Selection in the Generic Data Source does not work

Hi gurus,
I have some problem with the selection in the Generic Data Source.
I have created a view as a base of a Generic Data Source.
This view is based on several table; i.e.: VBUK-VBELN (Sales Order number), VBAP-ERDAT (creation date of Sales Order), VBAP-POSNR (Sales order item), VBAK-BSTNK (Customer Purchase order number).
In the view, some join conditions have been defined: VBUK-VBELN = VBAK-VBELN, VBUK-VBLN = VBAP-VBELN.
I want to extract the Sales Order number, Sales order item and Customer Purchase order number for the Sales order created on the previous year.
On the Generic Data Source, I select VBELN (Sales order number) and ERDAT (creation date of sales order) as selection.
However, when I run the extractor checker (RSA3) on this Generic Data Source, the selection does not work at all, i.e.:
eventhough I restricted the Sales order number and/or the creation date of sales order, the generic data source ignores the selection criteria and extract ALL data.
Does anyone ever have similar problem? Did I miss some step in the Generic DAta Source creation? How to fix this problem?
Thanks a lot in advance.
Best regards,
Fen

Hi Fen,
Just check what is the output you get for the same selection for the view you created.

Error while doing DELTA Extraction (generic data source)

Hi BW Experts,
In my R/3, I have a generic data source ZBUT_VW.
It receives data from a View which is created based on couple tables.
When I do full load to the corresponding ODS, it is successful.
But after that I delete the ODS and created CUBE with DELTA
I have Initialized delta.
When I do DELTA extraction, it fails.
The error The ALE inbox of the SAP BW is identical to the ALE outbox of the source system
and/or
the maximum wait time for this request has not yet run out
and/or
the batch job in the source system has not yet ended.
I delete the initialization load and trying to do DELTA extraction again and it Fails.
With the same error
Please let me know how can I resolve this problem.
URGENT
gaurav

I dont think it is possible to have to additive delta with creation date.
Try a full load to cube to check if the extractor is working.

Error while testing Generic Data Source extraction

I've created generic data source for Texts and Attributes in R/3 based on VIEW (Z table)
I get error "Error 6 in function module RSS_PROGRAM_GENERATE" while trying to test the data sources through RSO2
I guess there can be a lot of reasons... Please name me anybody who knows them...
thanx in advance

Hi,
Please Check the OSS note 328948 and it provides solution to same error what you have. Additionally you can have a look into this OSS note 705212 too.
Syntax error in the generated extraction program Symptom
You notice the error by one of the following symptoms:
The loading of transaction data from an R/3 system terminates with a syntax error in the generated extraction program. The monitor displays the error messages:
R3027 "Error & during the generation of the data transfer program"
RSM340 "Error in the source system"
The extraction within the extractor checker terminates with error message RJ028 "Error 6 in function module RSS_PROGRAM_GENERATE".The activation of transfer rules ends in BW with error message RG102 "Syntax error in GP$ERR$, row... (-> long text)" from the source system. Usually, the diagnosis in the long text of the error message is: "...could not be interpreted. Possible error causes: Incorrect notation or... "
Other terms
OLTP, extractor, data extraction, DataSource, Service API, SAPI,
R3 027, R3 27, RSM 340, RJ 028, RJ 28
Reason and Prerequisites
The error only occurs in the source system, if this contains Basis Release 3.1I and Service API (SAPI) 3.0C Support Package 6. SAPI 3.0C Support Package 6 is contained, for example, in PI 2003.1 Support Package 7 (see attached composite SAP note 673002).
Solution
To correct the problem you need service API 3.0C Support Package 7 in the affected source system. The attached composite SAP note 704971 explains in which software components service API 3.0C is contained, and what the corresponding Support Packages of these components are.
Alternatively, you can also copy the advance correction from the appendix.
Hope it helps.

Generic Data Source delta is not extracted

Hi,
There is a problem in extracting the delta records using Generic Data Source. Delta records ( New / Modified records ) are not posted in the RSA7.
I'll Explain you the Scenario I have done. Created a generic data source in R/3 using view. In the view there is a field Sales Order No. I have enabled the delta update for this field. In the generic delta i have chosen delta type as Numeric pointer.
Extracted the entire record using full update and after initializing the Delta, it extracts the delta record well ie. it only extracts the sequence of Sale Order No. First I extracted nine records(i.e 10001 to 10009) using full update. again I entered a record in underlying table with sale order no as 10011-10013. It extracts those records into BW system. Then again I made an entry in the table with sales order no 10010. But the record is not extracted. Even though I tried of specifying safety lower limit as -3. Still it not extracting the record(10010).
And what if I posted a value of sale order 10014 with the same. what should I do?? Help on this plz.
--Durai.S

Hi SVS,
Thanks for your reply.
I followed this in my scenario. But I don't understand why it is not extracting? even I specified the safety limit of upper and lower values in the generic delta.
Here the below explanation shows that the delta record can be extracted even if the pointer value is greater than the posted value.
Numeric pointer (last extracted value 10011; Data in underlying table (Max value = 10025) )
Data would be extracted from a min-value of 10010 (lower limit adjusts the last counter 10011 by specified value u2013 1)
max-value of 10020 (after adjustment for upper safety limit u2013 by 5). The current pointer would now indicate 10020 in
RSA7.

Data extraction through generic data source

Hi sap-BI experts,
i created the infoset query by using these transactions
SQ01,
SQ02,
SQ03 and the tables used are EKKO,EKPO and MARA.
and when i wanted to extract data from generic data source through infoset query
i am getting an error like this
'' specified table doesnot exist".
can i get the answer
Thanks,

Hi,
Do u selecting your info set under extraction from SAP query (Tcode - RSO2)? Make sure your infoset query active & available for reporting.

Code Page Setting while extracting data using Generic Data Source

Hi,
Can anybody tell me about the Code Page setting used in Generic Data Source in SAP BW 3.5?
I am extracting data from a Master Table using Generic data Source, but the data which is in Ukrane language is getting loaded as "#". Where do we set the Code Page for it?
Regards,
YK.

To continue with earlier question, is there any particular setting for a master data, to load non english data as a text of master data?
I want to load TEXT of a master in Ukraine language. I am extracting this text from the P table of same master (From Description Field). But TEXT is not getting populated whenever it is Ukraine language. English TEXT is populated correctly.
Please share your experiences...
Thanks,
YK.

Problem during extraction using generic data sources

Hi
While performing extraction(master data) using generic data sources I am getting a problem.
while selecting application component, I am unable to find SD to select it.What should I do?
I selected CRM as application component and did the extraction , it is successful.
But what about if we want to select SD? I am guessing it as an installation problem ... Anyone plz help me
Thank you
Deepthi

Hi Deepthi,
Looks like the RFC connection between source system and BW system is broken..
Contact your basis team to check the connection what went wrong.
once the connection is re-established you can gohead ...
Try out this procedure
Type Transaction SM59.
a.) Open the RFC Destinations.
b.) Find your Source System and double click on it.
c.) Technical setting should contain information regarding your source
system
d.) Logon Information should contain source system client and name &
password for you remote logon.
**Suggestion : our remote name for our R/3 was ALEREMOTE. We use
BWREMOTE so that we can monitor without confusion.
e.) Execute your 'Test Connection' & 'Remote Logon'. You connection
should be You should NOT be prompted for a password.
f.) Repeat above to verify RFCs for other systems

Can generic function module extractions possible with CRM data sources.

Hi Friends,
can generic function module extractions possible with CRM data sources.
90% extractions are generic function module extractions.
How is it possible without BW adapters..
It's very urgent ...Please.
Thanks,
Basava Raju

Hi Madhu,
Just curious ... if you already have a generic FM extractor then just go into it and find out where it is reading the data from. If its reading data from the CRM system then thre is no need for any BW adapter ... just in case you need any ABAP help ... post here ... I may be of use to you.

Generic data source with float field possible?

Hello,
when creating an generic data source using a view with a float field I get error R8359 (extract structure: You tried to generate an extract structure with the template structure .... This operation failed, because the template structure quantity fields or currency fields, for example, field ... refer to a different table.).
I changed the data element from ATFLV to e.g. FLOAT but it did not help.
SAP hint 335342 deals with this issue, but I just want to use the float number without the unit.
Is this possible or do I need to write a function module?
Best regards
Thomas

Hi,
you could try to add the unit table and field to your view. When saving the datasource in RSO2, you can choose to hide these fields if you don't want them extracted into BW.

Generic Data Source Creation Problem....URGENT!!!!!!!!!!!!!

Hello BW Experts...!
I need to create a Generic Data Source out of a table called VBSEGK... I was trying in the usual way with RSO2 , but when I press save button after entering the Table name the following error is coming:
" Invalid Extract Stucture Template VBSEGK of Data Source ZPARK_01"
and when I click on the error message its showing
Diagnosis
You tried to generate an extract structure with the template structure VBSEGK. This operation failed, because the template structure quantity fields or currency fields, for example, field DMBTR refer to a different table.
Procedure
Use the template structure to create a view or DDIC structure that does not contain the inadmissable fields.
VBSEGK is a standard table , so I cant change the Table structure. Can any one give me some idea of how to create Data source with this table ASAP ASAP please....
Please ask me questions if you didnt get this...
thanks

Hi Harish,
Please check OSS note 335342.
Symptom
The creation of a generic DataSource which is extracted from a DDIC view or a transparent table terminates with error message R8359:Invalid extract structure template &2 of Datasource &1
Other terms
OLTP, DataSource, extractor, data extraction, generic extractor
Reason and Prerequisites
The problem is caused by a program error.
Solution
The table or view used for extraction must have currency and unit fields within the field list of the table/view for all currency and quantity key figures.Otherwise the consistency of the extracted data cannot be ensured.To make the generation possible, check whether all key figures of your table refer to unit fields that are within the field list.If this is not the case, there are two possibilities:
1. A table is used for extraction.
Create a view in which you have a currency / unit field contained in the view for each key figure. The currency / unit field from the table must be included in the view to which the key figure actually refers.
Example:
Field WKGBTR of table COEP refers to the unit field WAERS of table TKA01. In a view that contains field COEP-WKGBTR, table TKA01 and field WAERS must be included in the field list.
If the currency or the unit a key figure refers to is not located in a table but in a structure, the key figure has to be removed from the view and read via a customer exit (see below). Structures cannot be included in a view.
ATTENTION!! Often the key of the table in which the referenced unit is located, does not agree with the key in the table with the corresponding key figure. In this case, the join condition of both tables is not unique in the view definition, that means for each key line of the table with the key figure, several lines of the table with the unit may be read: the result is a multiplying of the number of lines in the view by a factor corresponding to the number of lines that fit the key figure, in the unit table. To be able to deliver consistent data to a BW system, check whether the unit of the key figure in question should always have a fixed value. If yes then you can determine that in the view definition via 'GoTo -> Selection conditions'. If no, then you must proceed as follows:
a) Remove the key figure from the view
b) Define the DataSource
c) Enhance the extract structure by key figure and unit for each append (Transaction RSA6)
d) Add the key figure and the unit in a customer exit
2. A view is already used for the extraction
If it is not possible to obtain a unit of measure from a table on which the view is based, the unit field must be deleted from the field list.
A note in relation to the upward compatibility of BW-BCT InfoSources: BW-BCT 1.2B was not yet able to check units and currency fields. For this reason, it is possible that InfoSources which were defined in the source system as of BW-BCT 1.2B must be redefined as of 2000.1 in the manner described above. However, checks are absolutely essential for the consistency of the extracted data.
Regards,
Praveen
