Modify Auto-Rejection Reason for Supplier Spend-Authorization Request

Summary:

Requirement : We have a requirement that there will be 2 separate departments working as vendor administrators. Both will have ability to view and edit suppliers, however, only 1 group should have ability to promote supplier for spend-authorization. I looked up the security roles and anyone who is a supplier administrator will have the button to promote supplier.

To address the requirement, I create a spend-authorization approval rule such that request will get auto-rejected if someone from the group who should NOT have the access requested for supplier promotion.

Issue: User who are receiving auto-rejection of spend-authorization are not seeing any 'rejection reasons'.
