Question

I am creating a line chart from an Analysis Services cube, with a date category, a count data field, and a status series. Here’s a screenshot to explain:

I want to add the blue total line, which sums all the statuses together.

I don’t want to add a “Total” member to the Status dimension, because that wouldn’t make sense. I’ve tried adding another data field and scoping it to sum everything, but I can’t figure out how to make the series field only apply to a single data field—so this ends up duplicating all the statuses and getting 8 lines instead of 5.

This should be possible… I don’t want to resort to writing SQL against the underlying database.

Alright so I figured out a reasonable solution in MDX. I think it would be better solved in SSRS, but I haven’t figured that out yet.

The trick is to add the [Total] member to the result set, instead of adding it to the actual Dimension. Simplified MDX is here:

WITH 
MEMBER [Execution Status].[Execution Status].[Total] AS 
    AGGREGATE([Execution Status].[Execution Status].[Pass].Siblings)

SELECT 
    {[Measures].[Count]} ON COLUMNS,
    {[Execution Status].[Execution Status].Children,
     [Execution Status].[Execution Status].[Total] } ON ROWS

FROM [CUBE]

This defines an additional member for Total which aggregates all the Statuses. Then all the Status members as well as the Total are returned. SSRS doesn’t care–it still groups by the new set.

I did have some issues with getting the Aggregation to work, which is why I’m using [Pass].Siblings. [Execution Status].Children always returned (null), and [Execution Status].[All] returned 2x the correct answer, presumably because of the [All] member. I could manually enumerate all the statuses as well. Still not sure what the issue there is…
