User Account ManagementLocate this document in the navigation structure

User accounts have to be configured with the kind of user authentication that takes place when the GSDO calls web services on the SAP system. The following three options are offered:

  • Business User: The user logged on to the SAP Gateway logs on the SAP system using their own user and credentials.

  • Anonymous user: SAP system is called with an anonymous user.

  • Service User: SAP system is called with a predefined service user.

For setting up the communication from the SAP Gateway to the provider systems, only the Business User option is required.
