Preventing PO auto-creation

Summary:

My client reported that purchases from a supplier auto-generated requisitions and submitted POs for approval. Upon further research, we discovered that the associated supplier agreement had expired as of 6/30/2025. The agreement controls had the "auto-creation and submission of the PO" option unchecked, which was working until recently; however, they could not figure out why the POs were auto-generating and submitting for approval.

Upon further research, I also discovered the "Autogenerate orders from requester-negotiated requisition lines" setting was on in setup and maintenance, and informed them, but we would like to know the implications/downstream impacts of turning this setting off before moving forward, and/or if there is a better way to manage the auto-creation of requisitions.
