E9: Correcting Job Completion Errors

Hello,

We have just started using E9 and we keep having job completion errors. I keep seeing jobs completed for more than the production amount. These are user errors and I am investigating a BPM to prevent this from happening. My jobs all have a labor operation that is backflushed and a QC operation that is Qty Only.

My question is how do I correct a job that has had too many completions logged in Labor Entry? I have tried deleting the labor record, or logging a negative qty in labor entry and that corrects the job completion qty, but it does not appear to remove the extra labor applied in the backflush operation. And since the operation is backflushed I cannot manipulate it in Job Adjustment.

Is there a correct way to correct a job that has had too many completions in Labor Entry?

Thanks,
Tom Scott
