Hide/Filter Requisitions Imported from Specific External Systems from Buyer's Pool

Summary:

We have a requirement to hide or at least filter out requisitions that are imported from specific external systems on the Process Requisitions page. These requisitions will be converted into POs using a custom process with the Process Requisitions API.

We're considering using a line-level DFF attribute for this purpose. The idea is to set a default value of "Regular" for the DFF attribute so that all requisitions created through RSSP and other sources have this value, while the specific systems in question will send a different value. This DFF field would then be added to the Process Requisition search criteria to enable filtering, as shown below:
