After accepting the updates into their plans from the individual resource
updates from My Tasks. The PM can then look to see where there is
incomplete work in the past. This can be done using a formula.
IIf([Status Date]>55000,0,IIf([Finish]<=[Status Date] And [Actual
Finish]>55000,0,IIf([Actual Finish]=[Finish],1,IIf([Resume]<[Status
Date],0,IIf([Start]<[Status Date] And ([Resume]>55000 Or [Resume]<[Status
Date]),0,1)))))
Thir relies on the PM setting the appropriate status date. This will mark
any task that has incomplete work before the status date with a value of 0
and will mark all other task as 1.
