How to prevent to change PR during the Document Builder (PO Creation)

Content

Hi,

I would like to ask your help about the process of the PO creation. In the moment when our buyers are creating the PO from PR (using process purchase requisition option) and in the document builder, before we submit, we have an "Edit" option which allows us to change to PO line price after the requisition was already approved, so our concern here is the fact that we have automatic PO Approval setup so the buyer can change the price as high as he wish and the PO will get approved and this is not compliant.
