Hi Peter,
You can add comments in my blog, there is an option at the end of the page "Add a comment".
I have tested same scenario, 'create new condition record where the current condition record is deleted', and I have no issue. new condition record is create without deletion flag.
Perhaps you might me filling KOMV from existing data which is deleted, then make sure to clear KOMV-LOEVM_KO.
Hope my replay helps.
Regards,
