Suppressing the Logon Screen 

You can have the system suppress the normal logon screen for an SNC-protected logon request – if possible. The logon screen is suppressed if the following criteria are met:

·        The profile parameter snc/force_login_screen is set to the value "0".

●     The system can uniquely determine the user ID and client in the SAP system.

This is only possible if only one user ID exists in the SAP system with the corresponding SNC name, and this user exists in only one SAP system client. In this case, the SAP system can uniquely determine the user and the SAP system client and can log the user on without requiring any additional information.

If the SAP system cannot uniquely determine the user and client in the SAP system, then it produces the logon screen and requests the information needed to complete the logon.

If the profile parameter is set to the value "1", then the SAP system automatically displays the logon screen at every logon attempt.
