For example I want to create a measure called "Insured" and insured is determined by summing the Number of memeber months and dividing it by the number of months in the view. So if the users time period is a year then I would have the Sum of the member months / 12 etc. Member Months is a simple Sum of a value in my table but I do not know how to handle the time portion to get the Months as it applies to the current filter context.
