• What is the cause and solution for SAP error message /IWBEP/SBOD168 - Property '&1' is a complex type but ABAP field name is an element type ?

  The SAP error message /IWBEP/SBOD168 indicates that there is a mismatch between the data types defined in your OData service and the corresponding ABAP field names. Specifically, it suggests that a property defined as a complex type in your OData model is being mapped to an ABAP field that is defined as a simple element type. 
  Cause:
  
  Data Type Mismatch: The property in the OData service is defined as a complex type (which can contain multiple fields or properties), but the corresponding ABAP field is defined as a simple type (like a string, integer, etc.).
  Model Definition Error: There may be an error in the way the OData model is defined, where a complex type is incorrectly mapped to a simple field.
  Metadata Issues: The metadata of the OData service may not be correctly reflecting the structure of the underlying data model.
  
  Solution:
  
  Check OData Model: Review the OData service definition in the SAP Gateway Service Builder (transaction code SEGW). Ensure that the property in question is correctly defined as a complex type.
  Adjust ABAP Structure: If the property is indeed a complex type, ensure that the corresponding ABAP structure or data element is also defined as a complex type. You may need to create a new structure that matches the complex type definition.
  Update Mappings: If you have made changes to the OData model, ensure that the mappings between the OData properties and the ABAP fields are correctly set up in the service implementation.
  Regenerate Service: After making changes, regenerate the OData service and activate it to ensure that the changes take effect.
  Check Metadata: Use the OData service's metadata URL to check the structure of the service and ensure that it reflects the intended definitions.
