• What is the cause and solution for SAP error message /IWBEP/SBDSP_UI044 - Only one semantic field can be set as &1 ?

  The SAP error message /IWBEP/SBDSP_UI044 Only one semantic field can be set as &1 typically occurs in the context of SAP Gateway and OData services when there is an issue with the configuration of semantic fields in your OData model. This error indicates that the system expects only one semantic field to be defined for a particular property, but it has detected multiple fields being set.
  Cause:
  
  Multiple Semantic Fields: The error is triggered when more than one semantic field is defined for a single property in the OData service. Semantic fields are used to provide additional context about the data, such as indicating that a field is a key, a navigation property, or has some other specific meaning.
  Model Configuration Issues: There may be a misconfiguration in the OData model where properties are incorrectly defined or duplicated.
  Inconsistent Annotations: If annotations in the metadata are not consistent or are incorrectly defined, it can lead to this error.
  
  Solution:
  
  
  Check OData Model Configuration:
  
  Go to the OData service definition in the SAP Gateway Service Builder (transaction code SEGW).
  Review the properties of the entity types and ensure that only one semantic field is defined for each property that requires it.
  Remove any duplicate or conflicting semantic field definitions.
  
  
  
  Review Annotations:
  
  Check the annotations in the metadata for the OData service. Ensure that they are correctly defined and do not conflict with each other.
  If you are using annotations from an external source (like an annotation file), ensure that they are correctly mapped and do not define multiple semantics for the same property.
  
  
  
  Regenerate the Service:
  
  After making changes to the model, regenerate the OData service to ensure that the changes take effect.
  You can do this by right-clicking on the service in the Service Builder and selecting "Generate".
  
  
  
  Test the Service:
  
  After making the necessary adjustments, test the OData service to ensure that the error no longer occurs and that the service behaves as expected.
