ERP E-Commerce SU01 Logon 
When configuring the user type for ERP E-Commerce in Extended Configuration Management (XCM) you have the choice of two logon procedures if you are running an SU01 based logon configuration.

If you are running the Shop Management and Web-based User Management applications, only the logon configuration for SU01 users, and not SU05 users, is available to you.
● ERP E-Commerce logon
B2B user types: R3_SU01User, R3_SU01UserContactPerson, R3_SU01UserStandalone
· ERP E-Commerce logon via UME
B2B user types: R3_UMESU01User, R3_UMESU01UserContactPerson, R3_UMESU01UserStandalone
The logon configuration determines how users logon to the applications and the steps the system takes to verify users and perform checks on authorizations.
