  The SAP error message /IWFND/CM_ROLES001 No SAP system user found for external ID &1 typically occurs in the context of SAP Gateway and OData services. This error indicates that the system is unable to find a corresponding SAP user for the external ID provided in the request. Here’s a breakdown of the cause, potential solutions, and related information:
  Cause:
  
  Missing User Mapping: The external ID (often a user ID from an external system) does not have a corresponding SAP user in the system.
  Incorrect Configuration: The configuration for user mapping between the external system and SAP might be incorrect or incomplete.
  User Not Created: The user may not have been created in the SAP system, or the user ID may have been entered incorrectly.
  Authorization Issues: The user might exist, but the necessary authorizations to access the OData service are not granted.
  
  Solutions:
  
  
  Check User Mapping:
  
  Ensure that the external ID being used in the request is correctly mapped to an SAP user. You can check this in transaction SU01 (User Maintenance) or SU10 (Mass User Maintenance).
  If the external ID is supposed to map to a specific SAP user, ensure that the mapping is correctly set up in the relevant configuration.
  
  
  
  Create the User:
  
  If the user does not exist in the SAP system, create it using transaction SU01. Make sure to assign the necessary roles and authorizations.
  
  
  
  Verify Configuration:
  
  Check the configuration settings for the SAP Gateway and ensure that the user mapping is correctly configured. This may involve checking the settings in transaction SPRO under the relevant sections for SAP Gateway.
  
  
  
  Check Authorizations:
  
  Ensure that the user has the necessary authorizations to access the OData service. You can do this by checking the roles assigned to the user in transaction PFCG.
  
  
  
  Review Logs:
  
  Check the SAP Gateway logs for more detailed error messages. You can use transaction /IWFND/ERROR_LOG to see if there are additional details that can help diagnose the issue.
  
  
  
  Test with Different User:
  
  If possible, test the OData service with a different user that is known to work. This can help determine if the issue is specific to the user in question.
  
  
  
  Related Information:
  
  SAP Gateway: Understand how SAP Gateway works and how it handles user authentication and authorization.
