When the admin is creating a new user id in the SAP system, he has to specify which type of user to be assigned to a user id.

The following are the user types in SAP.

    4. Service User
    5. Reference User

1. Dialog users: – Dialog users are interactive users that include all log-on types of internet users. For example, thousands of users in your organization login to your system. The dialog users can log in to SAP GUI and it checks user password has expired or is initial, so the user can update his password. It also checks multiple logins and you can restrict them by parameters.

2. System Users: – It is used to communicate within the system. The system user can not log in to SAP GUI and it won’t check password details, so only the admin can change the password. For example internal RFC, External RFC.

3. Communication Users: – These users communicate between systems, they don’t log in to SAP GUI and systems check the details of password parameters.

4. Service Users: -This type of user is available to a group of users access. The system doesn’t check the details of passwords and only the admin can change the password. It accepts multiple logins to SAP systems.
