I just found an issue with my deployment that parts that are created in the Mirror process in an assembly are not getting new part numbers automatically. Has anyone else run into this?
EDIT: Also, it looks like producing files like this also adds a prefix of "fromparent+". This is especially annoying when it adds this text to date fields that are supposed to be read only on the datacard (Created by, approved by). You cannot update the file's data card until you correct this read only prefix.
Just ran accross this. Seems to happen when something is referencing a property that has been deleted, but not completely purged from the file. My bom had an equation trying to access "Manufacturer", but that field had been deleted. Was showing up as "fromparent+-" in my BOM. Fixed by adding the property back in.
