• What is the cause and solution for SAP error message /IWBEP/SBOD095 - Property '&1&2&3' is a key and must set nullable to false ?

  The SAP error message /IWBEP/SBOD095 Property '&1&2&3' is a key and must set nullable to false typically occurs in the context of SAP Gateway and OData services. This error indicates that a property defined as a key in your OData model is marked as nullable, which is not allowed. Key properties must always have a value and cannot be null.
  Cause:
  
  Key Property Definition: The property in question is defined as a key in the OData service but is also marked as nullable in the metadata.
  Model Configuration: There may be a mismatch in the configuration of the data model where the key properties are not correctly defined.
  Data Annotations: If you are using annotations to define the properties, the annotations may incorrectly specify that the key property can be null.
  
  Solution:
  To resolve this error, you need to ensure that the key properties in your OData model are set to not nullable. Here are the steps to do that:
  
  
  Check the Data Model:
  
  Open the data model in the SAP Gateway Service Builder (transaction code SEGW).
  Navigate to the entity type that contains the problematic property.
  
  
  
  Modify the Property:
  
  Select the property that is causing the error.
  Ensure that the property is marked as a key and that the "Nullable" option is set to false.
  If it is currently set to nullable, change it to not nullable.
  
  
  
  Regenerate the Service:
  
  After making the changes, regenerate the OData service.
  Activate the service and check if the error persists.
  
  
  
  Check Annotations:
  
  If you are using annotations, ensure that there are no conflicting annotations that might be causing the property to be treated as nullable.
  
  
  
  Test the Service:
  
  Once the changes are made, test the OData service to ensure that it works as expected without throwing the error.
  
  
  
  Related Information:
  
  OData Model: In OData, key properties are used to uniquely identify entities. They must always have a value, which is why they cannot be nullable.
  SAP Gateway: The SAP Gateway allows you to expose your SAP data as OData services, which can be consumed by various applications.
  Service Builder (SEGW): This is the transaction code used to create and manage OData services in SAP.
  
  By following these steps, you should be able to resolve the error and ensure that your OData service functions correctly.
