Generic Delta Function Module using...

Generic Delta Function Module using Update Mode (I_UPDATE) 24 Mar, 2010 1:07 AMHi BI Guru's

I am working in BW 7.0 and I need to develop a Generic Extractor that is Function Module based with Delta

Enabling.

The data selection has to be customized based on the Update Mode (F / D / S / C). We want to have a different

select if the update mode is full or delta.

For delta load we want aedat GE l_r_aedat-low - Take everything from last run

and for full we want to use aedat in l_r_aedat just the entered date

As SAP suggests, I copied the template FM RSAX_BIW_GET_DATA (which has II_UPDMODE as one of

the Import parameters: suppose to hold the Update Mode like Full or Delta) and adopted with our business

requirements. Te problem is when I run RSA3 to test the extraction it goes right to function FUNCTION

RSA3_GET_DATA_SIMPLE then it goes to my copyof FM RSAX_BIW_GET_DATA . ( I assume the

infopackage will do the same in BI as RSA3)

When it call my FM variable S_FNAME it does not pass I_UPDATE shown below, CALL FUNCTION

S_FNAME

EXPORTING

I_REQUNR = S_S_IF_SIMPLE-REQUNR

I_DSOURCE = S_S_IF_SIMPLE-DSOURCE

I_MAXSIZE = S_S_IF_SIMPLE-MAXSIZE

I_INITFLAG = S_S_IF_SIMPLE-INITFLAG

TABLES

How can I have the update mode passed to my FM ? Is there a way to change the function that is called in

RSA3?

Any isuggestions will be appreciated

Thanks,

George

Have a look this document:

Hope it helps...

Hi Ashish,

Thanks for the document, however it just describes the simple extract. I need to have the ability to use

I_UPDATE, it looks like your second document Functional Module Based Generic Datasource Part 2 may

cover this. Can you provide me with the link to this article if it is written? I tried a search but it did not come up.

Thanks

Hi!

You can use only pseudo delta in function module extraction.

look at :

Hi George. Hope you still around because I have a solution for you.

You can get a function module delta extractor to work with a function modeled after RSAX_BIW_GET_DATA

which contains the i_updmode.

1. It seems that datasource needs to be transactional.

2. Create your datasource in RSO2. Make sure you click the button for generic delta. Don't need to enter

anything in there if you don't need it in your function module.

3. After the datasource has been created, run a program with the following update statement:

UPDATE roosource

SET delta = 'E'

exmethod = 'F1'

WHERE oltpsource = 'name_of_your_datasource'.

4. Then go into your function module and rename the table parameter "e_t_data" to "e_t_" and then the name

of your extractor structure as entered in the datasource definition.

5. Go into RSA5 and reactivate your datasource.

Hello.

I am also working on a generic FM with delta enabled. Would you be so kind and post entire example? It would

be mush easier for us to do one ourself.

I am currently working with FM RSAX_BIW_GET_DATA.

Thanks in advance.

Hi AhmedZ,

a good example for delta handling is the function module PSBW_GET_WBS_ELEMENT of the DataSource

0WBS_ELEMT_ATTR...
