Everything up to date (at time of writing).

See Mike Pokraka's question here: (Also pinging Armin Beil )

I'm in the same state as Mike was: debugger has stopped working in most cases. I'm setting break points in ABAP Unit test methods. The only way they trigger, is if open a SAPGui session in eclipse, and run the unit tests from there - then I get into the Eclipse debug perspective. Otherwise, even BREAK... is ignored.

And I have the same issue as Mike regarding opening incidents.

    Hi Matthew,

    sorry for the inconvenience. According to your description and also for other reasons, I currently assume that the root cause of your issue actually differs from the one that Mike had.

    I was not able to reproduce your problem with Eclipse 2019-12, ADT 3.8.3 & ABAP Backend 7.50 SP 16 (You use SP13, but it's very unlikely that this makes the relevant difference). Debugging a unit test started from ADT works fine for me in this setup.

    Your hint that the same unit test actually brings up the ADT debugger when started from embedded GUI, is already quite valuable. But I need to ask some more questions to narrow it down:

    1) Is the issue occuring only during execution of ABAP unit from ADT or also in other scenarios?
    2) Is it occuring only for certain unit tests or for each and every unit test?
    3) Is it occuring only for your user or also for other users in that system?
    4) Is it occuring only in one certain backend system or also in different backends?
    5) After the issue occurred once: Do you have 100% reproducible failures when re-executing the unit test or does the debugger also work sporadically for your unit test?
    6) Please right click on a breakpoint and choose "Refresh Breakpoint Activation". Retry running the unit test and let me know whether that changed anything.
    7) Do you have the debug view (not debug perspective) opened and visible when triggering the unit test?
    8) Is anything written to the view "Error log" when you execute that unit test from ADT?

    Without ticket / remote access it's more difficult for me to provide support, so we will probably need a couple of questions and iterations. We can also do this via mail if you prefer.

    Best regards,

    Edit: Could you please also check the profile parameter "rfc/ext_debugging" via transaction RZ11. The value should be 3, not 0. For more details on the values see
