• What is the cause and solution for SAP error message /IWBEP/CM_V4_MED284 - Value control property '&1' in entity type '&2' must be technical ?

  The SAP error message /IWBEP/CM_V4_MED284 indicates that there is an issue with the value control property of an entity type in an OData service. Specifically, the error states that the value control property must be technical, meaning it should be a property that is not intended for user interaction and is typically used for internal processing.
  Cause:
  
  Incorrect Property Configuration: The property in question is likely configured as a non-technical property in the OData service definition, but it is being treated as a technical property.
  Model Definition Issues: The entity type may have been defined incorrectly in the data model, leading to a mismatch in expected property types.
  Inconsistent Metadata: There may be inconsistencies in the metadata definitions for the OData service, causing the system to misinterpret the property type.
  
  Solution:
  
  Check Property Definition: Review the definition of the entity type and ensure that the property in question is marked as a technical property. This can typically be done in the SAP Gateway Service Builder (transaction code SEGW).
  Adjust Annotations: If the property is intended to be technical, ensure that it is annotated correctly in the metadata. You may need to use the @sap:technical annotation to specify that the property is technical.
  Regenerate the Service: After making changes to the entity type or property definitions, regenerate the OData service to ensure that the changes take effect. This can be done in the Service Builder by right-clicking on the service and selecting "Generate".
  Check for Dependencies: Ensure that there are no dependencies or references to the property that might be causing it to be treated as non-technical.
  Test the Service: After making the necessary changes, test the OData service to confirm that the error has been resolved.
  
  Related Information:
  
  SAP Gateway: The error is related to the SAP Gateway framework, which is used to expose SAP data as OData services.
