Job production Qty Issues

Definitely turn on the change log for the JobHead table JobHead.ProdQty.

Passively monitor, maybe a dashboard that refreshes every 5 minutes for JobHead.ProdQty = 0. Then you will know shortly after it happens to talk to those involved while the even or transaction is fresh in them heads to find out exactly what’s done and then try to recreate.

Aggressively option, a BPM when the job creation date is less than to day so no new jobs and when JobHead.ProdQty = 0 either a massage to contact whoever then press Ok.
Or an Exception Message to Stop the process.

Is the Production Yield field checked on the jobs?

No it is not, we do not use production yield.

Do JobHead.ProdQty and JobProd.ProdQty say the same thing?

When the Job is first created, yes they match,
But during completing an operation the JobHead.ProQTY gets changed to 0 and the jobprod.ProdQTY stays as the original QTY.

For troubleshooting, this is the key. Does the Operation record or the linked Resource/Resource Group/Capability record have anything unusual in it? If in a TEST environment you change the operation does the problem go away?

This is what I am trying out right now.
