Edit Year To Date Calculation

Hi -

I created a Year To Date Calculation via the Buisness Intellligence Wizard. The Script is as follows:

( [Acctg Date].[Acctg Time Acctg Date Calculations].[Year to Date],
[Acctg Date].[AcctgYear].[AcctgYear].Members ) =
Aggregate(
{ [Acctg Date].[Acctg Time Acctg Date Calculations].DefaultMember } *
PeriodsToDate(
[Acctg Date].[Acctg Time].[AcctgYear],
[Acctg Date].[Acctg Time].CurrentMember
)
)

Now I'd like to edit it so that it produces "Inception To Date" to date ("Inception To Date" picks up all amounts from the beginning which in my case is 2002, as opposed to Year To Date which is from the beginning of the year).

To change to Inception To Date can I change the PeriodsToDate function to:


PeriodsToDate(
[Acctg Date].[Acctg Time].[2002],
[Acctg Date].[Acctg Time].CurrentMember
)



By the way, I'm very new to SSAS so the code is foreign somewhat foreign at this point.

Thanks,
Mark
