I'm not sure which SAP system you are in, but if you want to debug update modulers, you should probably not mark "System Debugging" as mentioned in the blog you link to, but the "Update Debugging" option in same Debugger settings Windows.

That works for me.

Probably you did not switch well "update debugging".

By the screenshot, I first thought you were answering that only "system debugging" was to be used, hopefully I then read the text 😉

Of course, System Debugging is still to be used to debug the system programs like SAPMSSY4 and SAPMSSY0 and many other ones.

(maybe you'd better post the screenshot of what is to be used, not the wrong one:

I found that screen shot in the link1 that Bodhisattwa Pal was referring to and I wanted to point out that, that setting was not for update debugging, but maybe I was not clear on that.
I know a lot about update debugging but I have never tried to use system debugging to find %_vb_calls parameter in SAPMSSY4 and SAPMSSY0 - that is certainly not necessary to do update debugging.

Kind regards
