Debugging a Popup Window

Sometimes we might want to start debugging from a popup window / information message, in this case we cannot type "/h" as the “OK Code” box is not available. 

Method 1:  From any SAP windows press the “Customize Local Layout” button (Alt + F12) and select

“Create Shortcut…”  Select system command in Type and and put /h in Command Provide desktop in location and click on finish.  A file is generated on your desktop. Now drag the file onto the popup window / information message or click on file and debugging is enabled!

Method 2:   Create a notepad file with below details:

[FUNCTION]
Command=/H
Title=Debugger
Type=SystemCommand  

Then save the above text file as a batch file. You can name it as debug.bat for example.

 

How to debug a background job which is running in an endless loop

How to debug a finished or crashed background job

Now just imagine that your background job finishes its execution so quickly, that you don't have a chance to attach a debugger to it in the Process Overview (SM50), or even worse: it crashed with a dump and you need to analyze what caused the dump. Just choose your job in the Job Overview (transaction SM37) and type "jdbg" into the command field. The debugger will start, and you just would need to press a couple of times Return (F7) to get out of the spool functions checks and you can debug your finished or crashed background job online in dialog.
