Loading of an assembly file in NX fails with the below error message.
This message implies that user has added components to an enforced piece part from the Teamcenter Structure manager.
Since the assembly was very big, user was unable to detect this enforced piece part.
SolutionTo detect the enforced piece part, in TC, send this assembly to structure manager, expand every node and capture a picture of this structure.
In NX, select "None" as the below setting and restart your NX session.
Now load the problematic assembly and validate the behavior.
After it loads successfully, then you can compare the assembly structure in NX to that of TC and can find out the culprit enforced piece part file.
After finding this part file, you can change the "Enforced Piece Part" setting inside this part file and can save this part file.
