1.  Go to Business Configuration work center.
2.  Select Overview view.
3.  Search and open Migration of Customers activity.
4.  Select Migrate Contacts using the Migration Tool.
5.  Upload the Migration Template using the Upload option.
6.  Select Execute Migration.

You are trying to add a new contact ID to an existing business partner ID and you may have entered the same relationship twice: once in the tab "Relationship" and also in the tab "Contact Details".

If you have a contact person and need to add the contact relationship to an account, you should only maintain this data in the tab "Contact Details".

The tab "Relationship" is meant to enter additional relationships for the contact, however not contact relationships.
