  The SAP error message /FTI/SERV_TECH_ERROR015 indicates that a property was passed to a function or method that is not recognized as a key property. This typically occurs in the context of SAP's Fiori or other applications that utilize the Fiori Technology Interface (FTI) for data handling and service calls.
  Cause:
  
  Incorrect Property Usage: The error suggests that a property that is not defined as a key property in the data model is being passed to a service or function that only accepts key properties.
  Data Model Mismatch: There may be a mismatch between the expected data model and the actual data being sent. This can happen if the data structure has changed or if there is a misconfiguration in the service definition.

  Modify Service Call: If you are developing or customizing the service, ensure that only key properties are included in the service call. Remove any non-key properties from the request.

  Debugging: Use debugging tools to trace the service call and identify where the unexpected property is being introduced. This can help pinpoint the source of the issue.
  Consult Documentation: Refer to the SAP documentation for the specific service or application you are working with to understand the expected input parameters and their definitions.
