• What is the cause and solution for SAP error message /IWBEP/CM_V4_MED287 - Value control property '&1' in complex type '&2' must be technical ?

  The SAP error message /IWBEP/CM_V4_MED287 indicates that there is an issue with the value control property of a complex type in an OData service. Specifically, it states that the value control property must be technical, meaning it should be defined in a way that is suitable for technical processing rather than for business logic.
  Cause:
  This error typically arises in the following scenarios:
  
  Incorrect Definition of Complex Type: The complex type in your OData service may have a property that is not marked as technical, but it is expected to be.
  Model Configuration Issues: There may be inconsistencies in the way the OData model is defined, particularly regarding the properties of complex types.
  Data Model Changes: If there have been recent changes to the data model or the OData service, it may lead to this error if the changes are not properly reflected in the service definition.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check the Complex Type Definition:
  
  Go to the definition of the complex type in your OData service.
  Ensure that the property in question is marked as a technical property. In the context of OData, this usually means it should be defined in a way that it is not intended for direct user interaction.
  
  
  
  Adjust the Property Settings:
  
  If the property is not intended for business use, you may need to set it as a technical property in the metadata.
  You can do this by modifying the annotations in the service definition or the underlying data model.
  
  
  
  Regenerate the OData Service:
  
  After making changes to the complex type definition, regenerate the OData service to ensure that the changes are applied.
  You can do this through transaction /IWFND/MAINT_SERVICE in the SAP GUI.
  
  
  
  Check for Dependencies:
  
  Ensure that there are no other dependencies or references that might be causing the issue. Sometimes, other parts of the model may reference the complex type incorrectly.
  
  
  
  Test the Service:
  
  After making the necessary changes, test the OData service to ensure that the error is resolved and that the service behaves as expected.
  
  
  
  Related Information:
  
  OData Services: Understanding how OData services work in SAP can help in troubleshooting issues related to service definitions and complex types.
  Technical Properties: Familiarize yourself with the concept of technical properties in OData, which are typically used for internal processing and should not be exposed to end-users.
  SAP Notes and Documentation: Check SAP Notes for any known issues or additional guidance related to this error message. The SAP Help Portal may also provide useful documentation on OData service development.
