• What is the cause and solution for SAP error message GW101 - No parameters changed ?

  The SAP error message GW101: No parameters changed typically occurs in the context of the SAP Gateway or when working with OData services. This error indicates that a request was made to update or modify data, but the system detected that no parameters or fields were actually changed in the request. As a result, the system does not perform any action because there is nothing to update.
  Causes:
  
  No Changes Made: The most common cause is that the data being sent in the update request is identical to the existing data in the database. This can happen if the user or application does not modify any fields before sending the request.
  Incorrect Request Format: The request might not be formatted correctly, leading to the system not recognizing any changes.
  Caching Issues: Sometimes, caching mechanisms may lead to the perception that no changes have been made.
  Business Logic: There may be business logic implemented in the backend that prevents updates if certain conditions are not met.
  
  Solutions:
  
  Verify Changes: Ensure that the data being sent in the update request actually contains changes. Compare the values being sent with the current values in the database.
  Check Request Payload: Review the request payload to ensure it is correctly formatted and includes the necessary fields that need to be updated.
  Debugging: If you have access to the backend, consider debugging the OData service to see how the request is being processed and where it might be failing.
  Clear Cache: If caching is suspected to be an issue, try clearing the cache or refreshing the data before making the request again.
  Review Business Logic: Check if there are any business rules or validations that might be preventing the update from being processed.
