If ABAP developer enable remote debugging in ABAP using RSRDEBUG, programmer can debug another user's session. The ABAP programmer has to configure debugging settings to debug the target user and then has to enable remote debugging in ABAP by executing the rsrdebug program.

This ABAP tutorial shows how to enable remote debugging in ABAP for a selected SAP user.

Debugging Settings and Set External Breakpoints

Open ABAP report or program code, for example the SAP Web Dynpro method within SE80 ABAP Workbench.
Using top menu follow selections: Utilities > Settings...
