Special processing is provided for extensions in the Supplier Registration and Supplier Information Change objects. These objects are used by a supplier to request creation (Supplier Registration) or modification (Supplier Information Change) of their Supplier master data object.

In the basic workflow for Registration, a prospective supplier creates the Supplier Registration to request an addition to the system, a buy-side supplier administrator approves (or denies) the request, and on approval, a Supplier master data object is created from the values entered on the Registration. There is a parallel workflow for Information Change Requests.

If the Supplier Registration or Supplier Information Change objects have extension attributes with identical names to those on the Supplier object itself, the extension values will also be propagated when the Supplier master data object is created or changed. This allows implementers to extend the capabilities of the Supplier registration and management functions.
