Changed the Relationship of master model drawing from "master" to "specification", ran Dry Run to create a clone file.
Later, executed the Import Assembly Into Teamcenter command again, and used the clone file for the import, noticed the drawing has its relation changed back to "master" again.
How to use the clone file for import and maintain that relation change to keep as "specification"?
Solution
Open the clone file in text editor, under the "Default Parameters":
Change the parameter for "&LOG Default Naming Technique:" from
"OSFILENAME Default_Name_Rule_Type: AS_ID" to "USER_NAME".
Save the clone file.
Now run the Import Assembly Into Teamcenter command, use the modified clone file. The relations for drawing will remain as "specification" as was modified to initially.
