• What is the cause and solution for SAP error message /IWBEP/SBOD110 - Property '&1&2&3' has got complex type and must set nullable to false ?

  The SAP error message /IWBEP/SBOD110 indicates that there is an issue with the definition of a property in an OData service. Specifically, the error states that a property has a complex type and that the nullable attribute must be set to false. This typically occurs when you are working with OData services in SAP Gateway and trying to define the structure of your data model.
  Cause:
  
  Complex Type Definition: The property in question is defined as a complex type, which means it is expected to contain multiple fields or properties.
  Nullable Setting: In OData, complex types cannot be nullable. This means that if a property is defined as a complex type, it must always have a value and cannot be left empty or null.
  
  Solution:
  To resolve this error, you need to adjust the definition of the property in your OData service:
  
  
  Check the Data Model: Go to the data model where the property is defined. This could be in the Data Definition (DD) or the Service Definition (SD) of your OData service.
  
  
  Modify the Property Definition:
  
  Locate the property that is causing the error.
  Ensure that the nullable attribute for this property is set to false. This can usually be done in the metadata or the model definition.
  If you are using a tool like SEGW (SAP Gateway Service Builder), you can navigate to the relevant entity type and modify the property settings.
  
  
  
  Regenerate the Service: After making the changes, regenerate the OData service to ensure that the changes take effect.
  
  
  Test the Service: Once the service is regenerated, test it to ensure that the error no longer occurs and that the service behaves as expected.
  
  
  Related Information:
  
  OData Specification: Familiarize yourself with the OData specification regarding complex types and their properties. Understanding how complex types work will help you avoid similar issues in the future.
  SAP Gateway Documentation: Review the SAP Gateway documentation for best practices on defining data models and handling complex types.
  Debugging Tools: Use debugging tools available in SAP to trace the error and understand the context in which it occurs.
  
  By following these steps, you should be able to resolve the error and ensure that your OData service is correctly defined.
