What you will need to do I think is to use a scoped assignment to perform the last ever nonempty calculation at the Contract level as well, and then the results of the calculation will aggregate up in the way you expect.

Thanks for replying for my questions. I did changes for Last Ever Non Empty and am showing an example with before and after change.

BEFORE
Row Labels 201301 201302 201303 201304 Grand Total
—————————————————————————————–
Contract-1 750 750
Contract-2 3,000 3,000 3,000 3,000
————————————————————————————–
Grand Total 750 3,000 3,000 3,000 3,000
—————————————————————————————-

AFTER
Row Labels 201301 201302 201303 201304 Grand Total
—————————————————————————————-
Contract-1 750 750 750 750 750
Contract-2 3,000 3,000 3,000 3,000 3,000
————————————————————————————
Grand Total 750 3,000 3,000 3,000 3,000
————————————————————————————
Expected 750 3,750 3,750 3,750 3,750
Grand Total
—————————————————————————————–

We are expecting 3,750 as Grand Total , but still its showing 3,000.
I can show screenshot of these exmples in my cube , but the reply option is not allowing attachments.

Is there any way we can get the Grand Total corrected ?

Hmm, can you give me a specific example of what’s happening and what you would like to happen?

Hi Magi, Did you get any working solution for Grand Total ? I am facing the same issue and need help. Thanks in advance

Hi Chris, Thanks for this great solution. I have question on grand total. Grand Total is still showing total based on Last Non Empty. Is there any way to show grand total including the last ever non empty value ? this question is similar to Magi question on March 16 2013. An answer will help a lot.
Thanks in advance.

Thinking about it, you could replace the IIF() with [Fiscal Calendar].[Fiscal Calendar].CURRENTMEMBER.LEVEL.MEMBERS.ITEM() – it would be more concise, but may or may not perform better.

I was just hoping to simplify the code IIF in to something that would sort of traverse the hierarchy and use the level corresponding to the level of the currentmember, but if that’s not possible all is well!

Thx Chris,
Chris

Hi Chris,

What exactly do you want to improve here? The nested IIFs could be replaced by a CASE statement or (even better) a scoped assignment, but I’m not sure if that would improve performance (if that’s your problem).

Thanks for this, I learned some useful methods! I have put it to method in one instance but am thinking you may have an idea how to improve it. In particular I want to make the formula work for a user browsing a relatively complete calendar hierarchy. Thoughts? The part I want to improve is the conditions in LastMovement:

WITH
MEMBER MEASURES.MaxDate AS
MAX(NULL:[Fiscal Calendar].[Fiscal Calendar].CURRENTMEMBER
, IIF(
[Measures].[Avg Stock Age]=0
,NULL
, COUNT(NULL:[Fiscal Calendar].[Fiscal Calendar].CURRENTMEMBER)
)
)

MEMBER CalendarLevel AS [Fiscal Calendar].[Fiscal Calendar].CURRENTMEMBER.LEVEL.ORDINAL

MEMBER MEASURES.LastMovement AS
IIF(
ISEMPTY(MEASURES.MaxDate)
, NULL
, ([Measures].[Avg Stock Age],
IIF(CalendarLevel = 4
,[Fiscal Calendar].[Fiscal Week].MEMBERS.ITEM(MEASURES.MAXDATE)
, IIF(CalendarLevel = 3
, [Fiscal Calendar].[Fiscal Month].MEMBERS.ITEM(MEASURES.MAXDATE)
, IIF(CalendarLevel = 2
, [Fiscal Calendar].[Fiscal Quarter].MEMBERS.ITEM(MEASURES.MAXDATE)
, NULL
)
)
)
)
)

, FORMAT_STRING = ‘#,#’

SELECT NON EMPTY {MaxDate
, [Measures].LastMovement
, [Measures].[Avg Stock Age]
} ON COLUMNS
, NON EMPTY (
[Stock].[Business].[Stock Name].&[1000000002225]
, {[Fiscal Calendar].[Fiscal Calendar].[Fiscal Week].&[315]:
[Fiscal Calendar].[Fiscal Calendar].[Fiscal Week].&[309]
}
) ON ROWS
FROM [Sales]

Hi Chriss,

Thank you for this useful post! It really helps a lot, especially in cases of balances, investments, and other financal scenarios like the one I work on.
I am using your solution and it works great, if the cube is sliced on Time dimension. The only problem comes with Grand Totals, and I really can’t understand how to resolve it, so I will greatly appreciate your help. The Grand Total sum by rows is correct (or I should say works as expected), but if you look at column Grand Total, Totals are SUMs until there are sales data, when there are no last sale for the period, then the Total is not SUM but Last Non Empty. I.e. Grand Total for 2004 and 2006 is 2643.61, which is not as expected. The same is appearing when for example the Year is on column, but the Cutomer is on Rows, then the Row Totals should be SUM, but they are “partially” sum and partially LastNonEmpty.
So I suppose my question is how to correct/control or replace those totals?
Thank you a lot!
