• What is the cause and solution for SAP error message /IWBEP/SBDSP_DM010 - Property &1 is mapped more than once with an output direction ?

  The SAP error message /IWBEP/SBDSP_DM010 Property &1 is mapped more than once with an output direction typically occurs in the context of SAP Gateway and OData services. This error indicates that a property in your data model is being mapped multiple times for output, which is not allowed.
  Cause:
  
  
  Duplicate Mapping: The property specified in the error message is mapped more than once in the service definition or in the data model. This can happen if:
  
  The same property is defined in multiple places (e.g., in different entity types or associations).
  There is a misconfiguration in the mapping of the data model to the OData service.
  
  
  
  Incorrect Annotations: Annotations in the metadata might be incorrectly defined, leading to multiple mappings for the same property.
  
  
  Model Changes: If the data model has been changed (e.g., properties added or removed) without properly updating the service definition, it can lead to inconsistencies.
  
  
  Solution:
  
  
  Check the Data Model: Review the data model to ensure that each property is only mapped once. Look for duplicate entries in the entity types or associations.
  
  
  Update Service Definition: If you have made changes to the data model, ensure that the service definition is updated accordingly. You may need to regenerate the service or refresh the metadata.
  
  
  Review Annotations: Check the annotations in your service definition to ensure that they are correctly defined and do not lead to multiple mappings.
  
  
  Use Transaction Code: You can use transaction code /IWFND/MAINT_SERVICE to manage your OData services and check for any inconsistencies.
  
  
  Regenerate the OData Service: If you have made changes to the underlying data model, consider regenerating the OData service to ensure that the mappings are correctly applied.
  
  
  Debugging: If the issue persists, you may need to debug the service to identify where the duplicate mapping is occurring.
