External Prospective Suppliers to be assigned only to Suppliers Bidder Role in Oracle Fusion
As per Oracle functionality, Supplier roles will get default based on "Manage Supplier User Roles" setup.
For external supplier registrations, when we provide URL to supplier to register, whether it is Prospective or Spend Authorize, roles will get defaulted based on "Default for Supplier Portal" roles.
For internal Supplier roles where Sourcing team creates the Supplier account on behalf, roles will get assigned based on what has been checked for "Default for Sourcing" setup.
As part of requirement, for external prospective suppliers using URL for registration, we would need to assign "Supplier Bidder" role only.
