• What is the cause and solution for SAP error message SADL_DRAFT_TOOL014 - Alternative Key element &1 is not of type UUID ?

  The SAP error message SADL_DRAFT_TOOL014 indicates that there is an issue with the alternative key element in your data model, specifically that it is not of type UUID (Universally Unique Identifier). This error typically arises in the context of using the SAP Draft Framework, which is often used in conjunction with the SAP Gateway and OData services.
  Cause:
  The error occurs when:
  
  An alternative key is defined in your data model, but the data type of that key does not match the expected UUID type.
  The alternative key is expected to be a unique identifier that conforms to the UUID format, but the actual data type defined in the model is different (e.g., a string or integer).
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check the Data Model:
  
  Review the data model where the alternative key is defined. Ensure that the key element is defined as a UUID type.
  If you are using a CDS (Core Data Services) view, check the annotations and ensure that the key is correctly annotated as a UUID.
  
  
  
  Modify the Key Definition:
  
  If the key is not defined as a UUID, you will need to modify the definition to ensure it is of the correct type. This may involve changing the data type in the underlying database table or the CDS view.
  
  
  
  Update the OData Service:
  
  After making changes to the data model, regenerate the OData service to ensure that the changes are reflected in the service metadata.
  
  
  
  Test the Changes:
  
  Once the changes are made, test the OData service to ensure that the error no longer occurs and that the alternative key is functioning as expected.
