week to date last week

  • I am using ssrs 2005 and trying to create a calculated member to show week to date last week for net sales. So, if this is the third day of the week, I would like to know what the week to date sales were for the same day last week. I have got the current week to date working using the following formula in a calculated member:

    AGGREGATE(PERIODSTODATE([Dim Date].[Fiscal Time].[Week Num]),[Measures].[Net Sales] )

    When I try to change that to add parallelperiods to it to get last weeks week to date, I get an error. The new formula that I am trying looks like:

    AGGREGATE(PERIODSTODATE(PARALLELPERIOD( [Dim Date].[Fiscal Time].[Week Num]

    ,1

    ,[Dim Date].[Fiscal Time].CurrentMember))

    ,[Measures].[Net Sales]

    )

    I have tried many variations to the above formula with no help. Thanks in advance for any help.

  • Hi,

    I would suggest a small change in your MDX calculation assuming our [Dim Date] is a hierarchy containing all the levels of the time period.

    Try using the below query in your calculation.Hope this works.

    AGGREGATE

    (

    PERIODSTODATE

    (

    [Dim Date].[Fiscal Time].[Week Num],

    PARALLELPERIOD

    (

    [Dim Date].[Fiscal Time].[Week Num]

    ,1

    ,[Dim Date].[Fiscal Time].CurrentMember))

    ,[Measures].[Net Sales]

    )

  • That worked and I now see why that wasn't working. Thanks for the quick response.
