param prob

hi ,
I have created 2 datasets. my first dataset quary parameter is BU. query is like following.

WITH

MEMBER [Measures].[Amount] AS 'IIF(ISEMPTY([Measures].[Amount Usd]),0,[Measures].[Amount Usd])'
MEMBER [Measures].[Description] AS '[Ledger—AccountCode].CurrentMember.Name'

SET [FilteredBUList] AS strtoset(@.BU)

SELECT
{[Measures].[Description],[Measures].[Amount]} ON COLUMNS,
[FilteredBUList] on rows

FROM Profitability

my second dataset query is like following,

SET [FilteredBUList] AS strtoset(@.BU)

SET [customtimeset] AS.....

SELECT
{[Measures].[Description],[Measures].[Amount]} ON COLUMNS,
intersect( [FilteredBUList],...) on rows

FROM Profitability

i need to map previous query BU parameter to the second dataset parameter. pls tel m the proper way.
cant access report parameter in this way from different dataset.
