I reviewed the video, found my problem.

thank you for your reply and your video!

scope([Date].[Calendar].[Calendar Year].&[2011]);

scope([Measures].[Most Frequent Price1]);
This=topcount(
[Price].[Price].[Price].MEMBERS,
1,
[Measures].[Invoice Transaction Count]
).Item(0).ITEM(0).MemberValue;

end scope;
end scope;

scope([Date].[Calendar].[Date].&[20110101]:[Date].[Calendar].[Date].&[20111231]);

scope([Measures].[Most Frequent Price1]);
This=topcount(
[Price].[Price].[Price].MEMBERS,
1,
[Measures].[Invoice Transaction Count]
).Item(0).ITEM(0).MemberValue;

end scope
end scope

thanks

This is in reference to the post http://social.technet.microsoft.com/Forums/en-US/sqlanalysisservices/thread/e0a4975f-8f19-40d0-90ff-4fcca1d301c1

Thanks for your help and I was able to solve the issue. Here is the modified code

CREATE MEMBER CURRENTCUBE.[Measures].[SalesAmount]
AS
null,
FORMAT_STRING = “0″,
VISIBLE = 1 ;

/* When the channel is at all Level and when a region is selected show region data */
SCOPE([In Market Channel].[InMarketChannelAttr].[All Channels],[In Market Region].[InMarketRegionAttr].members);
[Measures].[SalesAmount]=[Measures].[Re Sales Amount];
END SCOPE;

/* When the channel is at all Level and when all region show channel data */
SCOPE([In Market Channel].[InMarketChannelAttr].[All Channels],[In Market Region].[InMarketRegionAttr].[All Regions]);
[Measures].[SalesAmount]=[Measures].[Ch Sales Amount];
END SCOPE;

CREATE MEMBER CURRENTCUBE.[Measures].[TotalAmount]
AS
[Measures].[SalesAmount],
FORMAT_STRING = “0″,
VISIBLE = 1 ;

However I do find one scenario , If I change the Scope statements i.e. If I add the second scope statement at the first place and when I select multiple regions, I am encountering the same issue. However If I first write the scope of region members and then add a scope for all region member then it works fine.
Please let me know why the behaviour. I have no clue why this is happening.

Thanks once again !

I recreated your experiment and I see similar results but with a couple of exceptions noted below. I ‘d like to know the rules that are in effect here if anyone can offer an explanation. We are struggling with a couple of our scoped measures and this might help explain the results we are seeing.
Thanks,
Paul

CREATE MEMBER CURRENTCUBE.[Measures].[TESTCALC] AS 1;

SCOPE([Measures].[TESTCALC], [Time].[Fisca].[Year].Members);
THIS = 2;
END SCOPE;

SCOPE([Measures].[TESTCALC], [Time].[Fiscal].[All]);
THIS = 3;
END SCOPE;

SELECT
{[Measures].[TESTCALC]} ON COLUMNS,
{[Time].[Fiscal].[All]
,[Time].[Fiscal].[Year].[FY2010]
,[Time].[Fiscal].[Period].[FY2010-APR]} ON ROWS
FROM [Test Cube]

As expected, results in:
All 3
FY2010 2
FY2010-APR 1

Each of these queries also create results with values from the scope statements:

SELECT {[Measures].[TESTCALC]} ON COLUMNS FROM [Test Cube] WHERE {[Time].[Fiscal].[All]}
Result: 3

SELECT {[Measures].[TESTCALC]} ON COLUMNS FROM [Test Cube] WHERE {[Time].[Fiscal].[Year].[FY2010]}
Result: 2

SELECT {[Measures].[TESTCALC]} ON COLUMNS FROM [Test Cube] WHERE {[Time].[Fiscal].[Period].[FY2010-APR]}
Result: 1

Using a multi-member WHERE clause causes the unscoped value to appears:

SELECT {[Measures].[TESTCALC]} ON COLUMNS FROM [Test Cube]
WHERE {[Time].Fiscal].[Year].[FY2010], [Time].[Fiscal].[Year].[FY2011]}
Result: 1

Using Excel 2007, I get a different answer. Looking at Excel’s MDX, I see a subquery. This query returns the “all” scope value of 3.
SELECT FROM
(SELECT
({[Time].[Fiscal].[Year].&[2010],[Time].[Fiscal].[Year].&[2011]}) ON COLUMNS
FROM [Test Cube]) WHERE ([Measures].[TESTCALC])
Result: 3

returns the expected result (3 for [All Periods] and 2 for individual years). I would really like to know how the “specific rule” is defined and why this can be “intended behaviour”
