• What is the cause and solution for SAP error message SUSR_CERT126 - Could not create all explicit mappings ?

  The SAP error message SUSR_CERT126: Could not create all explicit mappings typically occurs in the context of user management and authorization, particularly when dealing with the SAP User Management Engine (UME) or when integrating with external identity providers.
  Cause:
  The error can arise due to several reasons, including:
  
  
  Missing or Incorrect Configuration: The system may not be properly configured to handle the mappings between users and roles or groups, especially if you are using an external identity provider (IdP) or Single Sign-On (SSO) solution.
  
  
  User Data Issues: There may be issues with the user data being processed, such as missing attributes or incorrect formats that prevent the system from creating the necessary mappings.
  
  
  Authorization Issues: The user or service account attempting to create the mappings may not have the necessary authorizations to perform this action.
  
  
  Technical Errors: There could be underlying technical issues, such as database connectivity problems or issues with the UME itself.
  
  
  Solution:
  To resolve the SUSR_CERT126 error, you can take the following steps:
  
  
  Check Configuration:
  
  Review the configuration settings for user mapping in the SAP system. Ensure that all necessary parameters are correctly set up, especially if you are using an external IdP.
  Verify the settings in transaction SU01 (User Maintenance) and PFCG (Role Maintenance) to ensure that roles and authorizations are correctly assigned.
  
  
  
  Validate User Data:
  
  Check the user data being processed for completeness and correctness. Ensure that all required attributes are present and correctly formatted.
  If you are importing users from an external source, ensure that the import process is functioning correctly.
  
  
  
  Review Authorizations:
  
  Ensure that the user or service account has the necessary authorizations to create mappings. You may need to assign additional roles or permissions.
  
  
  
  Check Logs:
  
  Review the system logs (transaction SLG1) for more detailed error messages that may provide additional context about the failure.
  Look for any related error messages that could indicate underlying issues.
  
  
  
  Test with a Different User:
  
  If possible, try to create mappings with a different user account that has the necessary permissions to see if the issue is user-specific.
