Thank you for your response — Unfortunately, I received an error with your suggested formula.
I was thinking about this and basically, the thing I want to check is total working days in the project base calendar versus an individual’s calendar. If vacation or other non working time has been set for an individual (which should almost always be the case), then the number of working days between the individual’s calendar and the project base calendar should be different, which be the condition I want to check.
If(# Working Days Resource Calendar <> (# Working Days Project Calendar, “Resource Calendar Prepared”, “Resource Calendar Not Prepared”)
Is there a way to accomplish this type of checking?
