• What is the cause and solution for SAP error message /IWBEP/CM_V4_MED025 - Type '&1' provided by application is not a structure ?

  The SAP error message /IWBEP/CM_V4_MED025 indicates that the type specified in your OData service is not recognized as a structure. This error typically occurs when the system expects a certain data type (usually a structure) but receives a different type (like a primitive type or an unsupported type).
  Cause:
  
  Incorrect Data Type Definition: The type you are trying to use in your OData service is not defined as a structure in the ABAP Dictionary.
  Mapping Issues: There may be a mismatch between the data model defined in the OData service and the underlying data model in the ABAP backend.
  Service Metadata: The metadata of the OData service may not be correctly defined or may not include the necessary structures.
  Model Configuration: The OData model might be incorrectly configured, leading to the system not recognizing the type as a structure.
  
  Solution:
  
  
  Check Data Type Definition:
  
  Go to the ABAP Dictionary (transaction SE11) and verify that the type you are using is indeed defined as a structure.
  If it is not a structure, you may need to create a new structure or modify the existing type.
  
  
  
  Review OData Service:
  
  Check the OData service definition in transaction /IWFND/MAINT_SERVICE to ensure that the service is correctly configured and activated.
  Ensure that the entity types in the service correspond to the correct structures in the ABAP backend.
  
  
  
  Update Metadata:
  
  If you have made changes to the data model or the structures, regenerate the metadata for the OData service. You can do this by using transaction /IWFND/MAINT_SERVICE and selecting the service, then choosing the option to regenerate the metadata.
  
  
  
  Check Model Configuration:
  
  Review the model configuration in the OData service to ensure that all entity types and their properties are correctly defined and mapped to the corresponding structures.
  
  
  
  Debugging:
  
  If the issue persists, consider debugging the OData service to trace where the error occurs. This can provide insights into what type is being passed and why it is not recognized as a structure.
