Help modifying MDX - Allow for Ownership Change in Team System

I am asking for your help solving a problem. I am very new to MDX and OLAP in general.

Here is my statement of the problem: Changing ownership of Bugs in Team System results in incorrect reporting of Completed Work.

I have crafted the following MDX , which works fine if Ownership of a Bug or Work Item is not changed.

=================================================================================

WITH

MEMBER [Measures].[Completed Work On Period Start] AS

(

(STRTOMember(@.prmStartDate)),

[Measures].[Microsoft_VSTS_Scheduling_CompletedWork]

)

MEMBER [Measures].[Completed Work On Period End] AS

(

(STRTOMember(@.prmEndDate)),

[Measures].[Microsoft_VSTS_Scheduling_CompletedWork]

)

MEMBER [Measures].[Completed_Work] AS

(

[Measures].[Completed Work On Period End] - [Measures].[Completed Work On Period Start]

)

SELECT NON EMPTY

(

FILTER

(

NONEMPTYCROSSJOIN

(

[Assigned To].[Person].[Person],

[Work Item].[System_Id].[System_Id],

[Work Item].[System_Title].[System_Title],

[Work Item].[System_WorkItemType].[System_WorkItemType],

[Measures].[Current Work Item Count],

4

),

[Measures].[Completed_Work] > 0

)

)

ON ROWS,

NON EMPTY

{

[Measures].[Work Item Url],

[Measures].[Completed_Work]

}

ON COLUMNS

FROM

[Team System]

=================================================================================

The problem arises when anyone changes ownership of a bug (or work item).

I have used [Changed By].[Person].[Person] and [Assigned To].[Person].[Person] as the first element in the NONEMPTYCROSSJOIN, and neither return the proper result.

BTW: I know that NONEMPTYCROSSJOIN is depreciated, but I am unsure how to replace it.

Thanks in advance.

Hi Doug:

At first glance your MDX look sound. No obvious reason why changing Work Item ownership results in the wrong answer. Which leads me to think the issue is in the dimensional model, or fact table. Not in the MDX of your query. As an aside, you asked how to emulate the NONEMPTYCROSSJOIN with a different statement. I created an example below with two equivalent statements. One uses the NONEMPTYCROSSJOIN, and the other uses a FILTER() with a CROSSJOIN to give the same results. The samples work on the Adventure Works database.

To help track down the root of your changing ownership problem it will help to see the sample fact table and query result before the problem is created and after the problem is created.

Hope this helps - PGoldy
