  The SAP error message /IWBEP/CM_CP024 OAuth flow not supported typically indicates that the OAuth flow being attempted is not supported by the current configuration of the SAP system or the specific service you are trying to access. This error is often encountered in scenarios involving SAP Gateway and OData services when trying to authenticate using OAuth 2.0.
  Causes:
  
  Unsupported OAuth Flow: The specific OAuth flow (e.g., Authorization Code, Implicit, Client Credentials) you are trying to use is not supported by the SAP system or the OData service.
  Configuration Issues: The OAuth settings in the SAP system may not be properly configured. This includes missing or incorrect client IDs, secrets, or redirect URIs.

  Solutions:
  
  
  Check OAuth Configuration:
  
  Ensure that the OAuth client is properly configured in the SAP system. This includes verifying the client ID, client secret, and redirect URIs.
