A user's ability to load an object, modify it, and then save the changes back to the Manufacturing Hub is determined by two primary factors:
-
the current read/write status of the object, which is determined by the Lock Management system of DPM
-
the current user's access rights (referred to as User Rights), as defined in Process Engineer
An object is in a read-only state for a user if that user does not have the appropriate access rights (as defined in Process Engineer), or if another user has already acquired a write-lock on the object of interest.
The links below describe the Lock Management and User Rights mechanisms of DPM.
