  Cause:
  
  Incorrect HTTP Method: The error indicates that the operation you are trying to perform requires the HTTP PATCH method, but a different method (like GET, POST, or PUT) is being used.
  Service Configuration: The OData service or API you are trying to access may be configured to only accept PATCH requests for updates, and other methods are not allowed.

  Use the Correct HTTP Method: Ensure that your request is using the PATCH method. If you are using a tool like Postman, make sure to select PATCH from the dropdown of HTTP methods.
  Check API Documentation: Review the API documentation for the specific OData service you are trying to use. It should specify which HTTP methods are supported for each operation.
  Update Client Code: If you are developing an application that interacts with the SAP system, ensure that the code is correctly set up to send PATCH requests when updating resources.
  Test with Different Tools: If you are unsure whether the issue is with your client, try using a different tool (like Postman or curl) to send a PATCH request to the same endpoint to see if the error persists.
  Review Service Implementation: If you have access to the backend, check the implementation of the OData service to ensure that it is correctly set up to handle PATCH requests.
