Skip PO Change order approval on updating PO distributions and DFFs on approved PO

Content

On an approved PO if we change PO distributions or update a DFF on PO line, system creates a change order and routes for approval. How can we prevent the PO going through approval process because there is nothing to approve from approvers point of view. We just like to have it auto approve.

Is this matter of just changing approval rules? For e.g Adding condition for tracking change in total dollar amounts.

Are there any other options to accomplish above?
