3399021 - Purchase order second approval is triggered after the reassignment of approval task

Previously, the purchase order approval only goes to approver A. However, due to absence of approver A, the approval task is reassigned to approver B. Then there is a second approval triggered for this purchase order and goes to approver A again.  Why this happens?

SAP Business ByDesign

The purchase order meets the condition of two approval steps in the system.

Previously, only one approval is triggered because skip reapproval is checked in approval steps and both approvals are supposed to go to approver A.

However when reassigning one of the approval task to approver B, system will trigger the second approval and assign to approver A.

This is expected behavior.
