Maintenance Job Entry - Equip ID Change Error


After a mass round of Equipment ID updates I have been asked to link all the old maintenance information with the new equipment IDs. This went ok for most jobs in the system that we have needing updates, but there are a few jobs that presented errors during the DMT, and even manually I cannot change the equipment IDs without getting the error “Part not found in the JobPart table.”

Any changes to those jobs are unable to be saved until I change the equipment ID to the old one, and then I can suddenly change things and save without an error. Any ideas what is going on here and how to get around this to reassign these jobs to the new equipment IDs?
