Snapshots and dates

Question

We have an accumulating snapshot fact table.  We take a snapshot of data once a week.
In our fact table we record Help Desk Ticket information, such as Time Open and Ticket Status.  Ticket Status is a FK back to the Ticket Status dimension so that we can slice on the status.
For a given month a particular Help Desk Ticket will have four records (possibly five) in the fact table.
So for Help Desk Ticket 123 my entries might look like:
Snapshot Date: 4/26/2014, Status: Open, DaysOpen: 5
Snapshot Date: 5/3/2014, Status: Open, DaysOpen: 12
Snapshot Date: 5/10/2014, Status: Open, DaysOpen: 19
Snapshot Date: 5/17/2014, Status: Open, DaysOpen: 26
Snapshot Date: 5/24/2014, Status: Closed, DaysOpen: 29
Snapshot Date: 5/31/2014, Status: Closed, DaysOpen: 29
Snapshot Date: 6/7/2014, Status: Closed, DaysOpen: 29
Snapshot Date: 6/14/2014, Status: Closed, DaysOpen: 29
When I write MDX statements to retrieve all Open tickets by month for the current year, I want my MDX to only look at the last snapshot of the month and look at its status.  So for the above example, the ticket should show as Open for April only. 
Likewise if I want to show Open tickets for the year by quarter the above ticket would not show at all because at the end of the quarter it was closed.
I'm thinking I need to do a SCOPE statement within the cube MDX so that the measure [Ticket Count] is applied at whatever level I'm at in the [Date Snapshot].[Year Hierarchy] structure (you're normal Year, Quarter, Month, Day hierarchy).
Is there another way or a better way to do this?

Answer 1

Didn't even need to do a scope statement.  Here's what I used and it appears to met my needs:
CREATE DYNAMIC SET CURRENTCUBE.[Snapshot End of Month]
AS
GENERATE
[Date Snapshot].[Year Hierarchy].[Month].Members
, BOTTOMCOUNT
[Date Snapshot].[Year Hierarchy].CurrentMember
* NONEMPTY
[Date Snapshot].[Standard Date].[Standard Date]
, [Number of Tickets]
, 1
, DISPLAY_FOLDER = 'Named Sets';
