Subcontract Operations Not Updating Properly In Engineering Workbench

I have an issue occurring that seems to have me and a colleague stumped. We have some UD fields included in PartOpr and ECOOpr that are used in Engineering Workbench, however for Sub Contract ops we’re running into a weird issue where nothing gets pushed back to PartOpr when checking in Parts through engineering workbench. To be more specific, if we make any changes to the UD fields we have we don’t even see data for those operations being pushed back through at all like the Check In and Update methods are just ignoring them all together. The only way we’ve seen that the check in process will even recognize updates to Sub Contract ops is if we make a change to another non-UD field, then sub contract ops seem to go through. Is there something we are overlooking here?

I can provide screenshots to step through the process if necessary but I wasn’t sure if those would help at the moment.

perhaps the Subcontact ops uses different methods and that’s why it’s not updating. the ud fields.
