Uri string is too long

I have an issue with running a report from BIDS. The report is fairly large with 6 parameters 2 of which have large > 3000 rows. When I select all values from each parameter, report in BIDS returns

An error occured during local report processing

Invalid URI: The Uri string is too long

When I limit the amount of parameter values to minimum, report runs fine.

I've found a couple of similar issue over the net and most were corresponding to timeout in BIDS. I've changed the timeout in BIDS and I still have the same error message.

Thanks for any thoughts!
