Max Month or Current Month

Thu, 20 Sep 2012 08:28:21 GMT

Hi,

Consider the following data

Month Value

201204 500

201205 750

201206 850

201207 600

201208 900

201209 (blank)

I want to show, in a text box, the value for max(Month()-1). The textbox should always show the Value 900 (for this specific set of data), even when I choose another Month. Of course when month 201210 is added the 201209 Value will be filled in, and this is at that point the Value that should be shown in the text box.

How should I construct such a formula ?

Thank you,

David

sum({<Month={"$(=max(Month)-1)"}>} Value)

But you need to add a check when Month - 1 goes to previous year.

Hi Ioannis,

Thanks for the input!

First of all, how do I check for previous year as you describe?

Also, when I use your formula it is not showing the Max()-1 result when I do a selection on month, in fact it returns the selected month's result. How can I adjust the formula to only return the Max()-1 month eventhough another month is explicitely selected?

Thank you,

David

=sum({<Month={"$(=max({<Month=>} Month)-1)"}>} Value)

and a check would be something like :

if(right(Month,2) - 1 < 52 etc
