• What is the cause and solution for SAP error message /IWBEP/CM_SBMG032 - Model Provider Class name and Data Provider Class name cannot be the same ?

  The SAP error message /IWBEP/CM_SBMG032 indicates that there is a conflict in the naming of the Model Provider Class and the Data Provider Class in the context of SAP Gateway service development. Specifically, it states that the Model Provider Class name and the Data Provider Class name cannot be the same.
  Cause:
  This error typically arises when you are trying to create or register a new OData service in SAP Gateway and you inadvertently set the same name for both the Model Provider Class and the Data Provider Class. In SAP Gateway, these two classes serve different purposes:
  
  Model Provider Class: This class is responsible for defining the data model and the structure of the OData service.
  Data Provider Class: This class is responsible for handling the actual data retrieval and manipulation logic for the OData service.
  
  Having the same name for both classes can lead to confusion in the framework, as it expects them to be distinct to properly differentiate between the model and the data handling logic.
  Solution:
  To resolve this error, you need to ensure that the Model Provider Class and the Data Provider Class have different names. Here are the steps to do this:
  
  
  Open the Service Builder (Transaction Code: SEGW): Navigate to the service you are working on.
  
  
  Check Class Names: Look at the properties of the service and check the names assigned to the Model Provider Class and the Data Provider Class.
  
  
  Rename One of the Classes: If both classes have the same name, rename one of them to ensure they are distinct. You can do this by:
  
  Right-clicking on the class in the Service Builder.
  Selecting the option to rename or create a new class with a different name.
  
  
  
  Regenerate the Service: After renaming, regenerate the service to ensure that the changes take effect.
  
  
  Activate the Service: Make sure to activate the service after making the changes.
  
  
  Test the Service: Finally, test the OData service to ensure that it is functioning correctly without any errors.
  
  
  Related Information:
