Using Function Module for extrcting data to BW
This is just my opinion but I could be wrong. Using a FM as an extractor, I can't see the data right away similar to the R3 transparent table format. I used RSA3 but the data always come out to 0. I am an ABAPer and have been used to another method using the regular way of extracting data, instead of using the FM, and the transparent table as a datasource. I usually check the data directly in the table to see anything got extracted. Using the structure, I can't see the data right away before I actually send it to BW.
May be I am not used to using the FM but what would be the best way to check the data before going through BW to start loading? Please advise.
