• What is the cause and solution for SAP error message SOAUTH2002 - OAuth 2.0 client ID and user ID should be identical ?

  The SAP error message SOAUTH2002 indicates that there is a mismatch between the OAuth 2.0 client ID and the user ID being used in the authentication process. This error typically arises in scenarios where OAuth 2.0 is implemented for authentication and authorization in SAP systems.
  Cause:
  The error occurs when the OAuth 2.0 client ID does not match the user ID that is being used for the authentication request. In OAuth 2.0, the client ID is a unique identifier for the application making the request, and it is expected that the user ID associated with that client ID should be the same for the authentication to succeed.
  Solution:
  To resolve the SOAUTH2002 error, you can take the following steps:
  
  
  Verify Client ID and User ID:
  
  Ensure that the client ID being used in the OAuth request matches the user ID. This means that the application (client) should be configured to use the correct user credentials.
  
  
  
  Check OAuth Configuration:
  
  Review the OAuth 2.0 configuration in your SAP system. Make sure that the client ID is correctly set up and that it is associated with the correct user ID in the OAuth provider settings.
  
  
  
  Update User Credentials:
  
  If necessary, update the user credentials in the OAuth client configuration to ensure they match the expected values.
  
  
  
  Review Authorization Scopes:
  
  Ensure that the authorization scopes requested by the client are appropriate for the user ID being used. Sometimes, insufficient permissions can lead to authentication issues.
  
  
  
  Test with Different User:
  
  If applicable, try using a different user ID that is known to work with the specified client ID to see if the issue persists.
  
  
  
  Check Logs:
  
  Review the logs for more detailed error messages or additional context that might help identify the root cause of the issue.
  
  
  
  Consult Documentation:
  
  Refer to the SAP documentation for OAuth 2.0 configuration and troubleshooting to ensure that all settings are correctly applied.
