Amount Only Requisitions

Hello,

We are on Financials 9.0. We have had an issue recently with requesters adding requisitions that should be flagged as "Amount Only", and are getting missed. This causes issues downstream with Vouchers/POs etc.

Is there any delivered way to force a requisition to be flagged as "Amount Only" based on, for example, the vendor selected on the requisition? We are trying to catch things up front.

Plan B could be to add additional approval layers to include our AP team (or something along those lines). These are obviously getting missed in our cuurent approval chain as well.

Any help would be appreciated.
