SSRS Report Builder 3.0 MDX Time/Date Parameter Default Value

Question

I have been struggling with this all week and have yet to find an answer. I have a fairly simple report with an Analysis Services Cube as the Data Source.

I am attempting to set the TimeDate parameter's default value to the previous date. I am familiar with how to do this normally, but am having difficulty with MDX.

The following expressions does work, but pulls 1/8/2011 as the Cube's data value are based on the number of days since 1/1/2011 (eg the value '1136' generates 2/9/2014).

="[Time Date].[Date].&["+DAY(CSTR(DAY(NOW())+"]"

Answer 1

The following should work:

="[Time Date].[Date].&[" + DateDiff(DAY, Date(2011, 1, 1), Today()) + "]"
