NX Newly created attribute in the template part file is not available in the Legacy Part Files in TCIN.

Create new attribute in the template part file and save to Teamcenter. While creating part, the new attribute is available, but not available in the legacy part files.

The new attribute is added in the template part file, but legacy part files are created with different template part file and hence you don’t see the new attribute.

To update in the legacy part files, attribute mapping can be done by creating same attribute in BMIDE, once you load the legacy parts and perform save operation then the new attribute gets updated in the legacy part files.
