Debugging user exit

Question

Dear Experts,
                 I found that the User Exit code for Transaction data coming from R/3 to BW is not working properly. I have to debug it. How do I debug it? Can somebody refer me to any documentation or tell me the method used to debug user exits? I know how to debug Update and Transfer rules.. but not user exits?
Thank you.

Answer 1

For update and transfer rules:
1) Load data till PSA.
2) Go to monitor and select details tab.
3) Open Processing node and on a data packet node right click and select simulate update.
4) On the next screen select the data provider and mark the update debugging in update rules and/or debugging in transfer rules
5) On the lower part select all records or selective records.
6) In the update rules, the program will first stop at a point where the different debugging points can be turned on or off. Some are on and some are off. Change them according to your requirements.
Debug User Exit: Assuming you want to debug extraction exit. Put a break point in the code and run in RSA3. If you are trying in production system, then select the enable debugging option in RSA3 and run the extractor.
