Approval Assignmnet is invisible after assigning the HR position to another Organization

 Hello, We are using PO Hierarchy Approval and facing one problem:

Approval Assignmnet is invisible after assigning the same HR position to another Organization

Ex: Initially the Postion A was assigned to Organization A_Org as well as assigning the Approval group to itself.
later, due to various reasons, we reassigned the Postion A to organization B_Org, but original approval assignment for the same postion missed in the form.


Is there anybody who can help me.

Thanks in advance.
Harry
