Details
After exporting Assembly Outside Teamcenter, some of components having different naming convention i.e. (PartName_Rev_1) instead of (PartName_Rev).
Solution
Export utility append "_n" if the exported name is duplicate. After applying the naming scheme, if name found to be duplicate then it will append.
If you don't want the duplicate names to be renamed then you can set "UGII_UGMGR_DUPLICATE_NAME_CHECK=true" which report the duplicate names which we can fix up.
