<p class=MsoNormal>Hi Julian,<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal><a href="http://jira.pentaho.com/browse/MONDRIAN-682">http://jira.pentaho.com/browse/MONDRIAN-682</a><o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>[Measures].[Number of Employees] - is distinct count
measure. <br>
<br>
Example: <br>
<br>
WITH SET [XL_Row_Dim_0] AS <br>
'VisualTotals(Distinct(Hierarchize({ <br>
Ascendants([Store].[All Stores].[USA].[OR]), <br>
Descendants([Store].[All Stores].[USA].[OR]), <br>
Ascendants([Store].[All Stores].[USA].[CA]), <br>
Descendants([Store].[All Stores].[USA].[CA])})))' <br>
SELECT NON EMPTY Hierarchize(Intersect({DrilldownLevel({ <br>
[Store].[All Stores] <br>
})}, [XL_Row_Dim_0])) ON COLUMNS <br>
FROM [HR] WHERE ([Measures].[Number of Employees]) <br>
<br>
Query should return: <br>
<br>
Axis #0: <br>
{[Measures].[Number of Employees]} <br>
Axis #1: <br>
{[Store].[All Stores]} <br>
{[Store].[All Stores].[USA]} <br>
Row #0: 329 <br>
Row #0: 329 <br>
<br>
But returns empty set. <br>
<br>
The same query with NOT distinct measure works.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>In distinct query cells are not being evaluated properly and
no queries is sent to database.<o:p></o:p></p>
<p class=MsoNormal>Could you please advise what is the best place to start
investigating.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Best regards,<o:p></o:p></p>
<p class=MsoNormal>Sergey<o:p></o:p></p>
