Those fields are not part of the OOTB webservice but you can of course add them to the existing mapping and use them as needed.
You have any issues adding them to the existing webservice mappings?
Thanks for the reply Jayson.
Unfortunately, I am just a developer that is consuming the OOTB web-services and do not have access to modify them. That will be the responsibility of our Remedy administrators.
I still can't believe that they would not include these fields OOTB.
