I’ve had an issue using transaction groups for as long as I can remember, and it looks like it’s caused from online edits in Logix. I have a transaction group that inserts a new row when a trigger changes (only execute once and prevent on group start). The trigger is an integer/count. I have noticed that on occasion, not very often, I will see duplicate rows, the only difference in data is the id (primary key). It seems like this happens when I make online edits in Logix (L81 v32). I have actually been fighting this for a while and think this is the root cause. The group execution is slow, 1 second.
Anyone else see this?
