I am going thru this also this week. It seems for me any bpm with a condition was having an issue. Until your post I was reviewing them and moving the condition into the abl code. It was good to refresh and combine several of them. Tonight I looked at removing the is not system query and putting the condition in the abl to eliminate the conflict.
I put an If ttDynamicQuery.Delivered = no Then Do: before the create UD25 and it seems to have stopped all of the issues. I have a lot of testing to do tomorrow, but I have tested 3 good so far.
