Two scenarios:
1.If I have raw material on a job that needs to go out for subcontract work and the subcon operation is not the last operation, which part number do I enter on the PO? Do I use the part number of the raw material that is associated with the subcon operation or do I use the “finished goods” part number on the job?
2.If I have raw material on a job that needs to go out for subcontract work and the subcontract operation is the only operation on the job, which part number goes on the PO? Is it the raw material part number because that is what I am actually sending out or do I put the finished goods part number on the PO since that is what will be returned from the vendor?
You can actually put any part number you want. On the subcontract tab you can enter whatever you want, it does not have to be the material or the finished part.
I think when you’re adding an operation to the quote/method/job, Epicor will default in the “finished” part number (from the job header/subassembly), but you can override it.
As for the PO: the part number pulled into the PO will be the same as you entered on the subcontract operation. They have to match as far as I’m aware.
In both scenarios, costing for the subcontract operation will be put to the job, which will only roll up to the finished good part number, so transactionally, it doesn’t matter which part displays on the Purchase Order. Both @jkane and @tsmith are correct, in that on the Operation card in Job Entry, you can enter either part number and that is the part that will display on the PO.
And that is the issue; I have seen different answers regarding the part number that goes on the PO. I always thought that it had to be the same as on the operation. This also prompted the 2nd scenario; If I send out raw material, but the finished product is return, what part number is used?
Epicor’s default is to use the JobHead (or JobAsmbl for subassemblies) part number, so unless someone has a really good reason to change it (which I’ve had once in 10 years or so), I’d leave it at that. Others may have other opinions. Questions to ask to determine you’re own usage might be who wants one way over another? or is one way somewhat more (or less) confusing than the other way for some parts/operations?
