  Cause:
  The error arises when:
  
  A function import is defined in the OData service with mandatory parameters.
  The client (e.g., an application or a front-end) attempts to call this function import without providing the required parameters.

  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check the OData Service Definition:
  
  Go to the SAP Gateway Service Builder (transaction code SEGW) and check the definition of the function import.
  Identify which parameters are marked as mandatory.
  
  
  
  Ensure Parameters are Provided:
  
  When calling the function import, ensure that all mandatory parameters are included in the request.
  If you are using a front-end application (like SAP Fiori), check the code or configuration to ensure that the parameters are being passed correctly.
  
  
  
  Test the Function Import:
  
  Use tools like Postman or the SAP Gateway Client (transaction code /IWFND/GW_CLIENT) to manually test the function import.
  Make sure to provide all required parameters and check the response.
  
  
  
  Debugging:
  
  If you are still facing issues, consider debugging the OData service to see how the parameters are being processed.
  Check for any transformations or mappings that might be affecting the parameters.
  
  
  
  Review Documentation:
  
  Consult the documentation for the specific OData service you are working with to understand the expected parameters and their formats.
