Smart SAP Assistant

• What is the cause and solution for SAP error message /IWBEP/CM_ANALYTICS066 - Model Provider Class and Data Provider Class cannot be same. ?

  The SAP error message /IWBEP/CM_ANALYTICS066 indicates that there is a conflict in the configuration of your OData service, specifically regarding the Model Provider Class and the Data Provider Class. This error typically arises when both classes are set to the same value, which is not allowed in the context of SAP Gateway services.
  Cause:
  The error occurs because:
  
  The Model Provider Class and the Data Provider Class are both set to the same class in the service definition. In SAP Gateway, these two classes serve different purposes:
  
  Model Provider Class: This class is responsible for defining the data model and structure of the OData service.
  Data Provider Class: This class is responsible for providing the actual data to the OData service.
  
  
  
  Having them set to the same class can lead to confusion in the service's operation, as the system cannot differentiate between the model and the data provider.
  Solution:
  To resolve this error, you need to ensure that the Model Provider Class and the Data Provider Class are set to different classes. Here are the steps to do this:
  
  
  Open the Service Definition:
  
  Go to the SAP Gateway Service Builder (transaction code SEGW).
  Open the project that is causing the error.
  
  
  
  Check the Class Assignments:
  
  In the project tree, right-click on the service and select "Service Implementation".
  Check the properties of the service to see the assigned Model Provider Class and Data Provider Class.
  
  
  
  Modify the Class Assignments:
  
  If both classes are the same, change one of them to a different class. You may need to create a new class for the Model Provider or Data Provider if you do not have one already.
  Ensure that the Model Provider Class is responsible for defining the structure and metadata, while the Data Provider Class should handle the data retrieval logic.
  
  
  
  Activate the Changes:
  
  After making the changes, activate the service and the classes involved.
  
  
  
  Test the Service:
  
  Once the changes are made and activated, test the OData service to ensure that it is functioning correctly without the error.
