The ability to "allow a supplier/vendor to still get into the supplier portal to invoice against existing orders and pay them for their services rendered or materials provided" but also "stop new POs from being created against that vendor" and potentially "changes to POs". this would be like weening a supplier off, allowing them to finish what was already there and pay them for what they are owed, but stop anything new from going out to them "inadvertantly" or "accidentally."
We are having hold codes in payables which stops the payment of the invoices related to the vendor or Invoices. similarly we are expecting same kind of functionality on supply chain side where the vendor when placed on Purchase hold should not be able to create/process new po's after placing on Purchase Hold. But still they should be able to pay the already created invoices for that PO's of that vendor.
