Safety limits for generic extraction

hi,
i would like to know data how data reacts for different type of scenarios, if my update method is calendar day.
1) when my upper limit is 1 and lower limit is 2.
2) when my upper limit is 1 and lower limit is 1.
3) when my upper limit is 2 and lower limit is 1.
please reply to this as i am in the process of creating the data source.

Hi,
Here I assume Delta enabled filed is on Creation date.
on 18.12.2009:(assume that last delta was happend on 17.12.2009 i.e which has brough the delta records created upto 16.12.2009)
In case 1) all delta records created upto 17.12.2009(due to UL 1 ) .And also brings again the delta records which were created on 15.12.2009 and 16.12.2009 due to LL 2 (even though those were uploaded by the delta loads on 16.12.2009 and 17.12.2009 respectively)
In case 2) all delta records created upto 17.12.2009(due to UL 1 ) .And also brings again the delta records which were created on 16.12.2009 due to LL 1 (even though those were uploaded by the delta loads on 17.12.2009 )

When to go for generic extraction using view and infoset query?

Hi,
Can anyone clarify me when we should go for generic extraction using view and when we should go for generic extraction using infoset query....
Also what is the difference between view and infoset?
I tried but could not find out....
Regards,
Kalyani.

Hi Kalyani,
We normally go for View or infoset when the data to be fetched in BW is distributed in different tables in SAP R/3.
Had the data been available in one table we can easily build our datasource on that table but if there are more tables then its not possible to do it without Views or Infosets. You can use Function Modules to build your datasource in case it involves complex logic to figure out the data from various tables.
Depending upon the table relationships we create view and include various fields from these tables in that view. Same is with the Infosets, you can have more flexible options like Outer Join, left outer Join etc.

Bussiness Scenario for GENERIC EXTRACTION

Hi friends,
 can any one explain me... in what situation we go for Generic Extractions..
The normal reason is When the Bussiness Content Datasource is not matching with our requirement.. we go for Generic extraction..
 I told like this only... but they are not satisfied with my answer.. and they asked .. tell me the bussiness scenario( in what situation u done generic extraction)
so, friends... could any one plz explain me any scenario... which you done for generic extraction...
 i will appriciate by giving points to the appropriate answers..

GENERIC DATA EXTRACTION USING FUNCTION MODULE
Difference between Generic Extraction and Enhancement of existing Extractor
1)Go to RSA6 and find the data source you need to enhance.--> Display
2)Double click on the Extract structure.
3)Now click on the append structure button to add the required field on to the existing structure.
4) add your required fields with ZZ appended to your field.
5) Save & Activate the append structure. Then go back and make sure you activate the extract structure also.
6) Now again go back to RSA6 and select your Data Source. But this time go to change Data Source to remove the hide option to the enhanced fields. By default theyll be in hide mode. If you dont remove the hide field then this field will not be seen in BW side.
7) Now go to SE38 to write the logic to populate the data into the enhanced field. Program name to write the logic is ZXRSAU01.
8) Check + Save + Activate.
9) Check in RSA3 if data is populated as per your requirement.
10) Replicate your Data Source.
11) Now go to Data Source/ Trans. Structure screen. Now you can see the enhanced field on the right hand side.Enhancements:
Enhancements:BW Side:
Go to CMOD.
1. To Save give Description  createcreate new projectgive the project name
2. Select the radio button Enhancement Assignment and give the Enhancement name you want and press Enter.
3. If the Enhancement is already assigned to some other project it will display the same message saying it is already assigned it some other project. Click on
4. If the Enhancement is not assigned to any project save.
5. Give RSR00001 (For Variable Exits)
6. Activate the Project.
7. and click on the components button.Now go to Display
8. Now Double click on EXIT_SAPLRRS0_001. In that you can see an include ZXRSRU01.
9. Double click on that include, it will say program name ZX are reserved for includes of exit Functions groups.
10. Just Press Enter.
11. Itll Pop-Up a window Create Object.saying Include ZX. Does not exits
12. That is where you have to write the code for the variable exits. BW: Virtual

Delta for Generic Extraction

Hi all,
Can anyone tell about delta for generic extraction i.e 3 options in detail and when do we use it.
thanks in advance,
chandra sekhar

When you want to customize existing datasources at R/3 sides then you can do that with customer exits.
Suppose if you want to add a column to the existing datasource then you will use append structures (Transaction SBIW-> Edit Data sources - Enhance Datasource) then to fill the column you will write the code in these Exits.
There are 4 types of Exits available.Function Group (XRSA)
EXIT_SAPLRSAP_001 Customer Function Call for Supplying Transaction Data
EXIT_SAPLRSAP_002 Customer Function Call for Supplying Master Data (Attributes)
EXIT_SAPLRSAP_003 Customer Function Call for Supplying Text
EXIT_SAPLRSAP_004 Customer Function Call for Supplying Hierarchies
As you are aware there 4 types since the datasources in R/3 are predefined to fill the data of BW viz, attributes,Text,Hierarchy and Transaction.
Check the below forum discussion for more information..

When we go for Views and Function Modules for Generic Extraction

Hi Experts,
Can you please explain when we go for extracting the data using Views and when we got using Function Modules using Generic Extraction from R/3 system to BW with examples. And also can you explain when we go for delta for the above both scenarios.
Thanks for you help in advance

Hi,
Scenario for Extarction using FM
Imagine the scenario where you need to extract data from
tables having no common field between them and thereby preventing you from creating a view on top of those tables..
Or simply consider tables that are highly unrelatd in terms of fields, but you have a requiremnt to extract data from them.

Scenarios for Generic extraction

Hello experts ,
Please give me some scenarios where we will go for the extraction using
function module,
infoset query,
View.
Thanks in advance,
pragya.

Hi Pragya,
Generic extractors are of 3 types:
1. Based on table/view
2. Based on Infoset Query
3. Based on Function module
In some cases Business Content will not give your required data sources , In such scenarios you need to develop your own data sources ( Views / Function modules ) , Then you can bring that data source to BW and use that .
if you can't find the suitable business content data source then you have to create
your own data source ( Generic )
or enhance the given data source.
Need for customized generic extractor
Business Content may not have a suitable
Data Source for your application.
Business Content may require additional enhancements that need data that is not supplied by SAP BW.
The application may not have its own generic data extraction method.
We have used our own custom programs to populate tables in SAP system.

Deltas for generic extraction.

Hi,
if i want use time stamp & calday for my generic extraction , i can use uppercase and lower case, wher can i give timings suppose want run deltas for 10am-10.30am.
regards
anitha

Hi,
Security interval upper limit The delta-relevant field is a timestamp.
The timestamp that was read last is 12:00:00. Delta extraction begins at 12:30:00. The security interval for the upper limit is 120 seconds. The selection interval for the delta request is: 12:00:00 to 12:28:00. When the extraction is finished, the pointer is set to 12:28:00. Security interval lower limit The delta-relevant field is a timestamp. After images are transferred. In BI the record is overwritten with the post-change status, for example, for master data. Any duplicate data records do not affect BI. The last read timestamp is 12:28:00. Delta extraction begins at 13:00. The security interval for the lower limit is 180 seconds. The selection interval for the delta request is: 12:25:00 to 13:00:00. When the extraction is finished, the pointer is set to 13:00:00.

Delta for generic extraction using FM

Hi All,
I am trying to create generic datasource using function module. I need to set delta functionality for this DS but I don't know how to set delta for FM.
Do I need to give delta specific field in RSO2? My delta specific field is either AEDAT or ERDAT? Is it possible? how to write code for this?
I have around 13 tables & there is no stadard DS for these table so is it correct way to use generic using FM or is there any other way?
plz suggest & if u have any step by step document for FM plz provide.

Hi Manesh,
Yes you need to set up your delta enabled field in RSO2 when you click the delta button for the datasource.
Usually for generic datasources we use any date field to genarete deltas and looks like you have the same (AEDAT and ERDAT a re date fields).
You dont need to write any code for this. Just provide any field for executing delta and initialize. It will get you the delta based on the date.
In some scenarios, we get postings happening on an older date and hence dates cannot be used, in those scenarios we can go by numeric pointer.
Creating a datasource on 13 tables, i ma not sure how efficient it would be (mainly depends on the data volume on these tables) but yah writing a function module will be fine.
Let me know in case of any clarification
Thanks
Sachin

Need code for Generic Extraction using FM using multiple tables.

Hi Experts,
We are doing a generic functional module extraction based on four tables - say,
Table TT1 u2013 with fields AA, BB.
Table TT2 u2013 with fields CC, DD.
Table TT3 u2013 with fields EE, FF.
Table TT4 u2013 with fields GG, HH.
The value of the field BB = DD.
The value of the field DD = FF.
The value of the field FF = HH.
The key field with which we have to extract data is AA.
We have created a structure for the above tables u2013 say STR containing all the fields from the above tables.
Now as such all the data from the tables is in the internal table ITF.
This data from the internal table is passed to the structure STR.
Somewhere, I think we are making a mistake. I do not know where.
When we check the datasource extraction in RSA3, we find that there is data only from the Table TT1. Data from other tables does not populate in the datasource.
We do not know where we went wrong.
Kindly help us.
Thanking you all in advance.
With Kind Regards,
Shreeem.

Hi,
You will have to use the select query with joins as given in the below example,
SELECT pcarrid pconnid ffldate bbookid
INTO CORRESPONDING FIELDS OF TABLE itab
FROM ( ( spfli AS p
            INNER JOIN sflight AS f ON pcarrid = fcarrid AND
                                       pconnid = fconnid    )
            INNER JOIN sbook   AS b ON bcarrid = fcarrid AND
                                       bconnid = fconnid AND
                                       bfldate = ffldate     )
WHERE p~cityfrom = 'FRANKFURT' AND
        p~cityto   = 'NEW YORK' AND
        fseatsmax > fseatsocc.
But I would suggest you to better create a Data base View with all the required tables and then use that view for data selection in your FM.

Durgesh.

FM FOR GENERIC EXTRACTION

Hi all,
Please go thru this link(I know its pain, but thanks). It is the question i had.
ERDAT or AEDAT
Many people contributed towards the problem. BUt still i had a few doubts, which were left unanswered. Siggi came up with a solution for me, in which i have a few more things to be cleared.
Siggi asked me to create a FM for all the custom fields and do a delta on it. Now, i wanna know if 0PM_ORDER has to be included in the FM too to select all the changes on the custom fields for a specific PM order.
Is there a way I can track changes in the system for all the custom fields? As Im not sure which field is tracked in which table? I understand you need to take a look at the system to answer my question, I was just curious if there was any generic way to track the changes to the fields.
Any help would be appreciated and fully rewarded.
Thanks,
Mav.

HI Siggi,
Nice to see u back, you make me feel much better. I would love to call you and talk to you. But I dont know the time difference between North America and Germany. If u can tell me what would be the best time to call you, I would surely find out the time difference and can give u a call. You can send me ur contact details to my personal email id, [email protected] Looking forward to talk to you. Even its fine with me if u prefer to just communicate thru the forum.
If u can give me ur email id, I can forward my report that I prepared as of now, that would give u a heads up and would make more sense to you, when I try to explain the scenario with my limited ABAP knowledge. Thanks for being there to help
Thanks once again,
Mav.

No IDOCS arrived from Source system to BI for generic extraction

Hi All,
While loading data from r\3 generic data source to BI, I am facing the below problem.
1. Using Full Load:-
The request from r\3 to psa turns red after a while. The request monitor says:
Error when updating Idocs in Source System
Diagnosis
Errors have been reported in Source System during IDoc update:
System Response
Some IDocs have error status.
Procedure
Check the IDocs in Source System . You do this using the extraction monitor.
Error handling:
How you resolve the errors depends on the error message you get.
Details Tab shows : request green
Under that Extraction tab shows red
missing messages.
Transfer (IDocs and TRFC): Errors occurred .
Request IDoc : Application document not posted
I ran Transaction BD87,BD73 and execute with proper selections.
Upon checking the idoc in source system Their status is 51 , which says
Diagnosis
The control parameters for communication with the BW server are not
complete. A BW PlugIn upgrade could be the cause of the problem.
System response
Procedure
Depending on the Release of the BW server, proceed as follows:
BW Server Release 1.2B: Source system: Update InfoSource metadata
BW Server Release >= 2.0A: Source system: Activate.
Manually i tried to push the idocs in the BW and source system using TRF but i dint found any records???
Soruce system connection is fine. Profile parameters are set properly and its active .. But still am getting the same problem.
Many thanks, I'll applicate your help.!
Rakesh

Hi
I am also facing the same problem. This happened after restoration of the original system with a copy of the production.
I am not able to get the IDOC posted in the source R3 system.
I did a debug and it failed when verifying the table, RSBASIDOC.
There appeared to be some missing records which need to be inserted.
I can't find a way to insert the missing record and since then, I am not able to proceed.
Have you resolved the issue?
can you share how it can be overcome?
Thanks a lot
