    A-ha. I googled ThrowIfMaxHttpCollectionKeysExceeded() and saw what some others have found. I have parameters which - if the user 'selects all' - results in lots of parameters. When I re-ran by deselecting the 'select all' the report runs fine.

    But that doesn't really fix the problem, as other users could still select 'select all'. Sounds like you haven't set up your SP to accept multi-value parameters, or the report shouldn't be set up to permit them
