3 Months Lag

3 Months Lag

3 Months Lag

Guys please help

I am trying to calculate a Avg of 3 month lag , which is basically , previous two months , plus number of days in the current month. Apparently i do not get the result set. I feel i might be ignoring something.

The basic scenario of calculation is
3 Months Rolling Avearge should be the past two completed months as well as the dates in the current month as well.  So taking the example above – if the reporting period for Feb was 01/30/2007 to 02/27/2007, and March was 02/28/2007 to 03/27/2007, the 3 MTD should then be the average from 01/30/2007 to 04/10/2007.

When i use the lag and last period functions, i get the result set which is equivalent to the orignal value.

the calculation i have used so far is as follows.

LastPeriods(3, [Tbl Date Key].[Ke Date].CurrentMember),

as well on the lag

   [Time].[Month].CurrentMember.Lag(2) :

But apparently , none of them works, would it be do something with Null.

please advise , am newbie to MDX and trying to place this solution.

Please advise if their is any other code.
