NX Importing altrep data to an existing item in Teamcenter.

While Importing altrep data to an existing item in Teamcenter using input clone log file, getting below error message.

Invalid master part.

After analyzing the input clone file, it is found that the respective master parts of the altreps are missing .

So to fix this issue you need to include the entries for these master parts in the clone log file.

You can enter the Cloning_Action as "use_existing" if you want to use the existing master part in the database. (if you do not want to overwrite the respective master part in the database)
