@ajborla please set the status to draft if its work in progress

there might be false positives from the open-abap runtime, I'll help with those once you finish the code

@larshp Converted PR to draft.

I believe the code is complete (it compiled, and all but one unit test passed).

I will close this PR, and resubmit when I receive a notification from you ?

Thank you very much for your help.

if a pull request is closed or merged I'll not look at it, I get a lot of notifications each day..

just have one pull request, push additional commits to it if needed, mark it as ready when ready
