We’re trying to figure out the proper way to scrap off the job. Just going to use an example.
A fully indented BOM has a subassembly for quantity 1 with 3 operations: cut, press, weld. In the MES work queue, the operations must be performed in sequence before it is available at the next resource work queue.
Say at the press operation, the assembly can no longer be used, and quantity 1 scrap is entered. What happens next?
I’ve found from a short test that the downstream operation(s) (weld in this case) is is still available to clock in to even though a true quantity was not completed from the prior operation. It was scrapped, but still marked as complete?
What’s the best way to handle scrap? Do you delete the assembly and add it back?
You don’t need to delete and re-add anything. The system is going to assume you’re going to deliver 1 piece from that assembly unless you change qtys. You can just start over from the first op. Optionally, you can go into Job adjustment and uncheck op complete to prevent people from seeing the “this op is complete, do you want to continue” pop up.
The closes to actually needing to do somethings is if the job is going to be completed short. Then you run production recalc or manually change the prod qty on the job to -1 (or however many pieces you wrecked) what is was before. That tells MRP that you’re down N pieces and it can adjust its recommendations accordingly.
So essentially you don’t need to do much, you can just start over from the beginning? When an operation is complete, it disappears from the work queue though. So in our case, we’d have to use job adjustment to mark the op as not complete so it repopulates in their queue?
The issue I was seeing (I’ll test again) is that the op is complete after scrapping the full quantity, but the work queue for the next resource group had the scrapped part in their “current work” section of the queue.
