Changing a callout number in NX does not sync to the same component in Structure Manager.
SolutionTo synch Callouts to Find Numbers in Teamcenter, you need to change the "Object Selection" to "Apply to Component Instance" when editing the attribute in NX.
1. Right click the component -> Properties -> Attributes.
2. Under the Apply To dropdown in the Context section, select Instance.
3. Edit the CALLOUT attribute value -> OK.
4. The Find No. in Teamcenter Structure Manager will update.
