  The SAP error message /IWBEP/MC_SB_GEN_USR032 typically occurs in the context of SAP Gateway and OData service development. This error indicates that there is an issue with the annotations in the Model Provider Class (MPC) extension. Specifically, it suggests that annotations should be manually maintained in the MPC extension rather than being automatically generated.
  Cause:
  The error is usually caused by one of the following reasons:
  
  Automatic Annotation Generation Disabled: The system is configured in such a way that automatic generation of annotations is not allowed or has been disabled.
  MPC Extension Issues: There may be issues with the Model Provider Class extension where the annotations are not properly defined or are missing.
  Incompatibility: The annotations defined in the Data Model may not be compatible with the OData service being generated.
  
  Solution:
  To resolve this error, you can follow these steps:
  
  
  Manually Maintain Annotations:
  
  Open the Model Provider Class (MPC) extension in the ABAP Workbench (SE80).
  Navigate to the method where the annotations are defined (usually in the define method).
  Manually add or adjust the annotations as needed. This may involve defining the annotations for your entity types, properties, or associations.
  
  
  
  Check Configuration:
  
  Ensure that the settings for annotation generation are correctly configured in your project. You may need to check the project settings in the SAP Gateway Service Builder (transaction code SEGW).
  
  
  
  Regenerate the Service:
  
  After making changes to the MPC extension, regenerate the OData service. This can be done in the Service Builder by right-clicking on the service and selecting "Regenerate".
  
  
  
  Test the Service:
  
  Once the annotations are manually maintained and the service is regenerated, test the OData service to ensure that it is functioning correctly and that the annotations are being recognized.

  Consult the SAP documentation for further details on how to properly maintain annotations in the MPC extension. This can provide additional context and examples.
