One of my manufacturing facilities is having a problem with components not printing on process order output.
In all cases, the master recipes themselves look fine when reviewed in C203. The components are properly allocated to phases (not superior operations). But when the process orders are generated, certain components are being assigned in the process orders themselves to the first superior operation, instead of to the phase that is indicated in the master recipe. Here is an example.
Here is the master recipe operation information as seen in C203:

And here is the material assignment list as seen in C203. Note that component material MM6030 is assigned to Phase 0035:

But when the process order is created, that same component material MM6030 is now assigned to superior operation 0001:

Here is some additional information that I was able to eke out of the folks at the manufacturing facility:
The operations in the master recipe did NOT originally contain operation 0001. It was added to the recipe in C202 after the recipe was initially saved.
Component Material MM6030 was not originally part of the BOM. It was added via C202 after the recipe was initially saved. A different material was originally in its place, and was assigned to a different phase. After the MM6030 was added to the BOM, the assignment field was blank, and the user assigned it to phase 0035.
Has anyone ever encountered a similar issue? If so, how was it resolved?
