Single Sign-On to SAP Systems
This section summarizes the different scenarios for Single Sign-On to SAP Systems. Which method of Single Sign-On (SSO) you use with a SAP System depends on various parameters, such as the release of the system. There are different prerequisites, for example, users must have the same user ID in all SAP Systems that are accessed via SSO with SAP logon tickets.
