Hello Team

 We are using Global deployments for transferring employees from one BG to another. In event of permanent transfers, oracle terminates employee records in the source BG and creates a new employee record in the new BG. 

When the perm transfer is initiated and completed, a new employee record is created with a new Person, Assignment, Contacts, and Person Extra Information in the target BG. The only related information or tie up is the employee number and the Party ID. And with every run of"Employee Update Program" Supplier and Site got inactivated as Employee details being end date in source BG from where the employee been transferred.
