Capping the total manhours / day ????

Hi Guys,

After resource loading the schedule, and having the schedule running for about a year now, the Client is asking us to cap the manpower to a certain number (i.e. 50 persos/day). that would be the maximum number or personnel working on the project. I need to resource level the schedule and get the new dates. how can I do that?

I need to tell the Primavera that the maximum number for hours per day (i.e. 50X10=500 hours/day) then resource level it, any ideas where I can do that?

In the P3 it was from Data -> Resource -> Upper Limit. but can't find it in P6!!!
