ER(SR 3-13708457231): Ability to hide/limit options available under 'Action' drop down in Buyer Work

Our client provide Buyer work center access to various business users based on their nature of work. Most of the users who have access to Buyer work center directly have access to unauthorized features to control the purchase orders. An example would be 'View Approval Workflow' under 'Actions' in the buyer work center screen.

Clients wants to restrict them for the data integrity but since these values where controlled by seeded purchasing lookup of 'PO_DOCUMENT_ACTIONS', we don't have an option to deactivate them.

Hence it would be a desirable feature to be made available in EBS (R12.1.3 & above).
