• What is the cause and solution for SAP error message SLC_CMN_API002 - Only HTTP method PATCH is supported ?

  The SAP error message SLC_CMN_API002: Only HTTP method PATCH is supported typically occurs when an API endpoint is expecting a PATCH request but receives a different HTTP method (like GET, POST, or PUT). This error is common in scenarios where you are trying to update a resource using an API that only allows partial updates via the PATCH method.
  Cause:
  
  Incorrect HTTP Method: The most common cause is that the client (e.g., an application or a script) is using an HTTP method that is not supported by the API endpoint. For example, if you are trying to update a resource but are using POST or PUT instead of PATCH.
  API Misconfiguration: The API endpoint may be misconfigured or not set up to handle the expected methods correctly.
  Client-Side Code Issues: There may be an issue in the client-side code where the wrong method is being called due to a programming error.
  
  Solution:
  
  Use the Correct HTTP Method: Ensure that your API call is using the PATCH method. If you are using a tool like Postman or writing code, make sure to specify PATCH as the method.
  
  Example in cURL:
  curl -X PATCH "https://api.example.com/resource/1" -H "Content-Type: application/json" -d '{"field": "value"}'
  
  
  
  Check API Documentation: Review the API documentation to confirm that the endpoint you are trying to access supports the PATCH method and to understand the expected request format.
  Debug Client Code: If you are using a programming language or framework to make the API call, check the code to ensure that it is correctly set up to use the PATCH method.
  Error Handling: Implement error handling in your client code to catch and log errors, which can help you identify issues more easily in the future.

  API Versioning: If you are working with different versions of an API, ensure that you are using the correct version that supports the PATCH method.
