What is the BW user exit RSR00001, and How does it work?
The SAP BW query exit RSR00001 is an Enhancement for Global Variables in Reporting. It is called up several times
during the execution of a report. The parameter I_STEP is populated with a number from 0 to 3 to specify at what point the enhancement is being called.
i.e.
If I_STEP = 1, then Call has taken place directly before any variable variable entry has been made. This can be used to pre populate selection variables
If I_STEP = 2, then then call has taken place directly after variable entry. This step is only started up when a variable is not input ready and could not be filled when I_STEP was equal to 1.
If I_STEP = 3, you can check the values of the variables. Triggering an exception (RAISE) causes the variable screen to appear once more. Afterwhich, I_STEP=2 is also called again.
If I_STEP = 0, then the enhancement is not called from the variable screen. The call can come from the authorization check or from the Monitor.
