Hi Vilmos,
I don't want to add additional parameters and change the existing report set up as I don't want to confuse users that are used to using the query selection that is available currently.
I have tried adding in an additional parameter to the data contract but even though it appears set up correctly I can't seem to be able to receive it in the data provider class. Is there no way to intercept or call the data provider class and send it values for processing?
