PO triggered for re-approval when the price is decreased

Dear SRM Experts,

We are on SRM 5.0 and using ECS.

In our system, when the price of the PO is reduced, approval workflow is triggered once again. As per my understanding, the workflow should only trigger for the PO when the price is increased.

Any idea?

With Kind Regards
