how to stop or hold supplier registration process

Hi,

We have a requirement to stop or hold supplier registration for new vendors based on the supplier qualification outcome.

Specifically, we would like to understand the following:

Is there a way to prevent the “Promote to Spend Authorized” action when the supplier qualification outcome is Disqualified / Not Satisfactory?

Also, is there a way to automatically restrict or place a hold on invoice creation for existing suppliers whose qualification outcome is Disqualified / Not Satisfactory?

Would like to Propose below Process:

1. Internal Requestor creates a supplier registration request (Prospective supplier).

2 . Supplier receives portal access to provide company details and complete qualification questionnaires.
