Supplier Portal- Custom role for supplier to prevent submitting invoices
We would like to create a custom role for certain suppliers to prevent submitting invoices via Supplier portal. I see that the seeded role "Supplier Accounts Receivable Specialist " needs to be copied and modified to achieve this. I need to know what are the priveleges that needs to be removed. Should this be removed in the Role Hierarchy or the Function security policies?
Is there any document to setup the custom role?
