SSRS 2008 How to rollup values using a group and recursive parent

Question

User1955997337 posted

Hi,

Im having an issue where I can't get my row values to total upwards when using a tablix and the 'recursive parent' option.  The following should help explain what im trying to achieve:

My Dataset:

;with cols as
(
 SELECT 1 colID, 'C1' col
 UNION SELECT 2, 'C2' 
)
, rows as
(
 SELECT 1 RowID, 'R1' row, null ParentID
 UNION SELECT 2, 'R2', 1
 UNION SELECT 3, 'R3', 2 
 UNION SELECT 4, 'R4', 2 
 UNION SELECT 5, 'R5', 1 
 UNION SELECT 6, 'R6', 1 
)
,data
AS
(
 SELECT 3 RowID, 1 as Amount
 UNION SELECT 4 RowID, 2 as Amount
)
SELECT r.RowID, r.row, c.colID, c.col, d.Amount, r.ParentID
FROM rows r 
CROSS JOIN cols c
LEFT JOIN data d on d.RowID = r.RowID

In my 'RowGroup' properties I go to 'advanced' and then set 'Recursive parent' to be 'ParentID'  and I've also set the padding left to be '=level()*20 & "pt"' to show the indent of the parent - child relationship

My matrix configuration and output looks like the following.  Notice how R1 and R2 have no values.  I want them to show '3' as this is the rolled up total of the children rows.

Thanks for all your help

Hi schott19,

You could try setting something like this.

Sum(Fields!XXXXX.Value,"Group1",Recursive)

Hi Chris,

Thanks for you reply.  You are correct - this works when there is one column but when I have a dynamic number of columns it sums all of the columns and applied that value to the roll up.

Sorry - I should of said in my initial post that I have multiple columns and not just one.  I don't believe it is possible as you need to consider the scope of the row and column.  SUM only allows one scope hence summing across all columns :(

Thanks
