Is the source work relationship impacted when you cancel the work relationship created by a global transfer or global temporary assignment?

Global transfer: Yes, the cancel impacts the source work relationship from where the global transfer was initiated. The assignment update in the source work relationship is removed and the source work relationship becomes active.

Global temporary assignment: No, the cancel doesn’t impact the source work relationship from where the global temporary assignment was initiated. To reverse the transaction after cancellation of the destination work relationship, you must delete the assignment update in the source assignment which was created as part of the global temporary assignment.
