When sending e-mails from the workflow and from the Invoice Monitor in the SAP GUI, the e-mail address was previously determined based on the SAP user master. This feature has been enhanced to provide full S/4HANA compatibility.

Background: In S/4HANA, it is possible to link users with business partners of the type "employee". This works via API or via the SAP Fiori App "Maintain employees".

Transaction BP does not allow this link. Users linked in this way have the IDADTYPE indicator in the USR21 table with the values 02, 03 or 04. In addition, the table USR21 contains the personnel number, which serves as a link to the business partner (table BUT000, field PERSNUMBER).

The e-mail address of a user linked to a business partner is in the business-partner master and no longer in the SAP user master. The e-mail address is now determined via the BUPA_ADDRESS_GET_DETAIL function module.
