Monthly Average (Expected)

Hi, I want to create a calculation in the cube (thinking that it can be done on that way). Please help me, you'll save a life :P

Problem:

TICKET NR

The table above lists some ticket records in my db. I have two measure;

* Total Count of Ticket
* Average Count of Ticket

First one works fine as expected...

Here is the pivot view yearly and monthly. The total results are produced by Total Count of Ticket.
My second measure's result is as I waited but not my expected one as you see below.

I think you've got my problem ;-) The average provided by my measure is
total ticket count / count of transaction month

but I want to calculate the average with some other measurement;

If the year ended (past year)
Monthly Average is calculated by total ticket count / 12

If the year not ended (current year)
Monthly Average is calculated by total ticket count / number of last month

Let me show over the tables...

ASE has 6 tickets for 5 months in 2006 and
my expected monthly average of 2006 for ASE is 6/12=0,5 (divided by 12 = end of 2006)

BEU has 1 tickets for 1 months in 2007 (my last recorded month on db is Feb 2007 also) and
my expected monthly average of 2007 for BEU is 1/2=0,5 (divided by 2 = Feb)

Well, I think there is a super-dev would explain how to do it with a calculation (calculated member, right?)
Not good at MDX but waiting for your solution.

Thanks.

I've built a very small solution based on your data.

It consists of 1 fact table and 4 degenerate dimensions (Ticket,Customer,City,Month).

I've created 2 calculated member: the first one count months in the year, the second calculate the average based on the first one

It works fine (the average returns the data you expect) but it could be not exactly what you want (your real business scenario should be more complex!).

If you contact me via e-mail I can send you the SQL db (actually only 1 table!!!) and the AS solution.
