• What is the cause and solution for SAP error message /IWBEP/CM_MGW_RT092 - Method '&1' not implemented in model provider class ?

  The SAP error message /IWBEP/CM_MGW_RT092 Method '&1' not implemented in model provider class typically occurs in the context of SAP Gateway and OData services. This error indicates that a specific method (like GET, POST, PUT, DELETE, etc.) is being called on an OData service, but the corresponding method has not been implemented in the model provider class.
  Cause:
  
  Missing Implementation: The method that is being called is not implemented in the model provider class. This can happen if the service was generated but the necessary methods were not implemented.
  Incorrect Service Configuration: The OData service might not be correctly configured to handle the requested operation.
  Model Provider Class Issues: There may be issues with the model provider class itself, such as it not being activated or not being correctly associated with the OData service.
  Service Versioning: If there are multiple versions of the service, the wrong version might be called that does not have the method implemented.
  
  Solution:
  
  
  Implement the Missing Method:
  
  Go to the model provider class (usually a class that implements the interface IF_MGW_APPL_SRV).
  Implement the required method (e.g., GET_ENTITY, CREATE_ENTITY, etc.) based on the operation that is being called.
  Ensure that the method signature matches what is expected by the OData framework.
  
  
  
  Check Service Configuration:
  
  Ensure that the OData service is correctly configured in the SAP Gateway Service Builder (transaction code SEGW).
  Check the service registration in transaction /IWFND/MAINT_SERVICE to ensure it is active.
  
  
  
  Activate the Model Provider Class:
  
  If you have made changes to the model provider class, ensure that it is activated. You can do this in the ABAP Workbench (transaction SE80).
  
  
  
  Debugging:
  
  Use the debugger to trace the execution and see where the call is failing. This can provide insights into whether the correct method is being called and why it is not implemented.
  
  
  
  Check for Versioning Issues:
  
  If you have multiple versions of the service, ensure that you are calling the correct version that has the method implemented.
