Process MRP not creating UD link

We created a couple UD fields in a table called JobOper_UD. When MRP creates a new Job, it creates the operations, but it does not create the UD link for the operations. Am I missing something?

Did you regenerate the data model?

If you open the Extended User Defined Table Maintenance,

Is your data model in sync? If it’s not green and says in sync, the data table needs to be regenerated.

If you haven’t done it, it’s on the server in the Epicor Administration Console here:

I always restart the task agent afterwards, but I don’t think it’s necessary. It’s also recommended to regenerate the data model when the server is not being heavily used.

Yes, I have done that. So far, I have only seen this happen with MRP jobs.
