I see you have already gotten a lot of good info from Sergey. (What a surprise!) If it were me I would crank up Code References and see how many GROUP BY clauses there are in the application. If it isn't a huge number it might be worth taking the time to fix them rather than ignoring non-compliant SQL code via SET ENGINEBEHAVIOR.

So do you think you're going to be able to focus on your work over there? <g>
