• What is the cause and solution for SAP error message SAML2074 - Authentication failed: CUA - User has not system assignment ?

  The SAP error message SAML2074 indicates that the authentication process has failed because the user does not have a system assignment in the Central User Administration (CUA) environment. This typically occurs in scenarios where a user is trying to log in to an SAP system that is part of a CUA landscape, but their user profile is not properly assigned to the relevant child systems.
  Cause:
  
  User Not Assigned to System: The user has not been assigned to the specific child system in the CUA configuration.
  User Deactivation: The user might be deactivated in the CUA or the child system.
  Missing Authorizations: The user may lack the necessary authorizations to access the system.
  CUA Configuration Issues: There may be issues with the CUA configuration itself, such as synchronization problems between the central system and the child systems.
  
  Solution:
  
  
  Check User Assignment:
  
  Go to the CUA central system and check if the user is assigned to the relevant child system.
  Use transaction SU01 to check the user details and ensure that the user is assigned to the correct system.
  
  
  
  Assign User to System:
  
  If the user is not assigned, you can assign them to the child system using transaction SU01 in the CUA central system.
  Ensure that the user is created in the child system if it does not exist.
  
  
  
  Check User Status:
  
  Verify that the user is active and not locked or deactivated in both the CUA and the child system.
  
  
  
  Synchronize User Data:
  
  If changes were made, ensure that the user data is synchronized between the CUA and the child systems. You can use transaction SCUA to perform synchronization.
  
  
  
  Review Authorizations:
  
  Ensure that the user has the necessary authorizations to log in to the system. This may involve checking roles and profiles assigned to the user.
  
  
  
  Check CUA Configuration:
  
  Review the CUA configuration settings to ensure that everything is set up correctly. This includes checking the RFC connections and ensuring that the child systems are properly configured in the CUA.
