  The SAP error message /IWFND/CM_MGW207 $Orderby is not supported in NOTIFICATIONSTORE service typically occurs when you are trying to use the $orderby query option in an OData service that does not support it. This is common in services that are designed to work with notifications or events, where ordering may not be applicable or supported.
  Cause:
  
  Service Limitation: The specific OData service you are using (in this case, the NOTIFICATIONSTORE service) does not support the $orderby query option. This is often by design, as the data returned may not have a meaningful order or the service may not be optimized for sorting.
  Incorrect Query: The query being sent to the OData service includes the $orderby parameter, which is not supported by the service.
  
  Solution:
  
  Remove $orderby: The simplest solution is to modify your OData query to remove the $orderby parameter. This will allow the request to be processed without error.
  Check Documentation: Review the documentation for the NOTIFICATIONSTORE service to understand its capabilities and limitations. This will help you determine what query options are supported.
  Alternative Sorting: If you need the data in a specific order, consider sorting the data on the client side after retrieving it, rather than relying on the OData service to do it for you.
  Custom Implementation: If ordering is essential for your application, you may need to implement a custom OData service that supports the $orderby functionality, or check if there are other services available that meet your requirements.
