What happens if I reassign a responsibility?

The responsibility you reassign is immediately visible in the assignment record of the person to whom it's reassigned. The From Date of the responsibility is the current date, and there's no To Date.

Here's what happens in the assignment record of the person from whom the responsibility is being removed. The current date becomes the To Date if there's currently no To Date. Otherwise, the existing To Date remains unchanged.

The scope of the responsibility remains the same. The change is visible in the Work Contacts list of affected people when the records are next viewed.
