    Frequent Customers

      I am having trouble figuring out how to create a field that gives me the amount of days since the last time the customer checked out. For instance, I have James who checked in on 1/8/2014 and checked out on 1/9/2014. He then came back on 1/12/2014. I want to calculate the amount of days since he last came in. It should say its been 3 days since he last came in. I am thinking of using peek commands and previous commands but I can't figure out a way to do this.

          If you create a straight table with Client as the dimension, and the following expression, it should do a count of the days from the most recent check out and most recent check in


          max( total <Client> [Check Out]) - max( total <Client> [Check In])

            if you just want to count the days since last check out taking as reference today, then you can use an expression like this:


            Today() - max([Check Out])



            if you want your expression to be more dynamic, you would need to use something like this:


            max(Date) - max([Check Out])


            hope this helps,
