• What is the cause and solution for SAP error message /IWBEP/SBDSP_DM015 - Key property &1 must have an input mapping ?

  The SAP error message /IWBEP/SBDSP_DM015 Key property &1 must have an input mapping typically occurs in the context of SAP Gateway and OData services. This error indicates that a key property in your OData service is not properly mapped for input, which means that the system cannot determine how to handle the key property when processing requests.
  Cause:
  
  Missing Input Mapping: The key property in the OData model does not have an associated input mapping defined in the service implementation. This can happen if the key property is not included in the input structure of the relevant operation (e.g., Create, Update).
  Incorrect Configuration: The OData service might not be configured correctly, leading to the key property not being recognized as part of the input.
  Model Definition Issues: There may be issues in the definition of the data model where the key property is not properly defined or linked to the input parameters.
  
  Solution:
  
  
  Check Input Mapping:
  
  Go to the Service Implementation in the SAP Gateway Service Builder (transaction code SEGW).
  Locate the entity type that contains the key property.
  Ensure that the key property is included in the input structure for the relevant operation (e.g., Create, Update).
  If it is missing, add the key property to the input structure.
  
  
  
  Update the Model:
  
  If you have made changes to the model, regenerate the runtime artifacts. This can be done by right-clicking on the project in the Service Builder and selecting "Generate Runtime Objects."
  Activate the service after making changes.
  
  
  
  Check Annotations:
  
  Ensure that the annotations for the key property are correctly defined in the metadata. This includes checking if the property is marked as a key in the entity type definition.
  
  
  
  Test the Service:
  
  After making the necessary changes, test the OData service using the SAP Gateway Client (transaction code /IWFND/GW_CLIENT) to ensure that the error is resolved.
  
  
  
  Review Documentation:
  
  Consult the SAP documentation or help resources for additional guidance on OData service implementation and key property mapping.
