• What is the cause and solution for SAP error message /IWBEP/CM_V4_MED387 - Value control property '&1' for '&2' of compl. type '&3' is not primitive ?

  The SAP error message /IWBEP/CM_V4_MED387 typically occurs in the context of OData services when there is an issue with the value control property of a complex type in your data model. This error indicates that the specified property is not a primitive type, which is required for certain operations in OData services.
  Cause:
  
  Non-Primitive Type: The error arises when a property defined in a complex type is expected to be a primitive type (like string, integer, boolean, etc.) but is instead defined as a complex type or collection.
  Incorrect Metadata Definition: The metadata definition for the OData service may have incorrect or incomplete definitions for the complex types and their properties.
  Service Implementation Issues: There may be issues in the implementation of the OData service, such as incorrect handling of complex types in the service logic.
  
  Solution:
  
  Check Metadata: Review the metadata of your OData service to ensure that the properties of the complex types are defined correctly. Make sure that the properties that are expected to be primitive types are indeed defined as such.
  Adjust Data Model: If you have control over the data model, consider changing the definition of the property in question to ensure it is a primitive type if that is what is required by your application logic.
  Service Implementation: If the error is related to the implementation of the OData service, check the code where the complex types are being handled. Ensure that you are not trying to assign or manipulate complex types where primitive types are expected.
  Testing: After making changes, test the OData service again to ensure that the error is resolved.
