It should not be possible to submit an invoice with a payment method that differs from those listed on the vendor account.
We have vendors who only accept certain types of payment, such as wire transfers. This can be documented at the account level of vendor records. However, an invoice can still be manually created that uses a payment method not used by that vendor, and it can go all the way through to issue a payment the vendor cannot accept, such as a check. There is a blue alert, but it does not block submission of the invoice. Testing the Alma Invoice Review Rules, this will prevent EDI or file loaded invoices from loading In Approval, but since most of these invoices are manually created, that does not work.
