Approval of the application
The customer reviews the application and uses the Complete option if the information provided
      by the supplier is appropriate. Else, the customer can use the Incomplete option. During the
      review process, the status of the application is set to Under Review. Only the customer with
      the administrator role can approve, decline, or send the application back to the supplier. The
      supplier is registered only after the application is approved by the customer and a business
      ID is generated. The Business Partner ID is linked to the External Entity.
  Note: The existing business partner can also link the business ID with the
        external entity using the  option on the
          External Entity/Business Partner Mapping page.
