• What is the cause and solution for SAP error message /IWBEP/SBOD444 - Complex Property not allowed. Select Primitive Property ?

  The SAP error message /IWBEP/SBOD444 Complex Property not allowed. Select Primitive Property typically occurs in the context of SAP Gateway and OData services when you are trying to use a complex property in a context where only primitive properties are allowed. This can happen during data retrieval or when defining the structure of an OData service.
  Cause:
  
  Complex Property Usage: The error indicates that you are attempting to use a complex property (which can contain multiple fields or attributes) in a situation where only primitive properties (like strings, integers, booleans) are expected.
  OData Service Definition: The OData service might be incorrectly defined, where a complex type is being used in a filter, selection, or projection that only supports primitive types.
  Query Parameters: If you are making a request to the OData service and specifying query parameters, you might be trying to filter or select a complex property instead of a primitive one.
  
  Solution:
  
  Check the OData Service Definition: Review the service definition in the SAP Gateway Service Builder (transaction code SEGW). Ensure that complex properties are not being used in places where only primitive properties are allowed.
  Modify the Query: If you are making an OData request, ensure that you are only selecting or filtering on primitive properties. For example, instead of trying to access a complex property directly, access its individual primitive properties.
  Adjust the Data Model: If necessary, consider adjusting your data model to avoid using complex properties in contexts that do not support them. This might involve flattening the data structure or creating additional primitive properties that can be used instead.
  Testing: After making changes, test the OData service again to ensure that the error is resolved.
  
  Related Information:
  
  OData Protocol: Understanding the OData protocol and how it handles complex and primitive types can help in designing your services correctly.
  SAP Gateway Documentation: Refer to the official SAP documentation for Gateway and OData services for best practices and guidelines on defining data models.
  Debugging Tools: Use tools like the SAP Gateway Client (transaction code /IWFND/GW_CLIENT) to test your OData services and see the structure of the data being returned.
  
  By following these steps, you should be able to resolve the error and ensure that your OData service is functioning correctly.
