Displaying subtotals for each group item in a Matrix or Group Matrix Report.

Question

Hi,
I have generated a Report as follows:
month1 month2 month3
M1 R1 P1 x y z
P2 a b c
R2 P3 d e f
M2 R3 P4 g h i
R4 P5 k l m
Is it possible to display the subtotals per each category as follows:
month1 month2 month3
M1 R1 P1 x y z
P2 a b c
-------------------------- x+a y+b z+c
R2 P3 d e f
------------ (x+a)+d (y+b)+e (z+c)+f
M2 R3 P4 g h i
R4 P5 k l m
------------ g+k h+l i+m
---- ((x+a)+d) ((y+b)+e) ((z+c)+f)
+ (g+k) + (h+i) + (i+m)
waiting for the solution desparately.

Answer 1

Your digram isn't very clear. It looks like you have a matrix that is made up of:
Across Group (G_Across) producing: month1, month2, month3
Down Group (G_Down1) producing: M1, M2
Down Group (G_Down2) producing: R1, R2, R3, R4
Down Group (G_Down3) producing: P1, P2, P3, P4, P5
and then you have the matrix cell values: x, y, z, a, b, ... m
Basically, you want to introduce a summary column at the G_Down2 level that is a running summary, resetting at G_Across.
To do this you need to create a matrix summary with the correct product order and reset value. The product order determines when the value is calculated. In your case, you want the value to be calculated: once Per G_Across, then once per G_Down1, then once per G_Down2. Leaving the reset value at "Report" will give you the subtotal values for all columns. You need to re-set this to G_Across since you want to only get a sub-total for each column.
Steps:
- Create a summary column in the data-model in the matrix group with the following:
Name: CS_SubTotal
Source: <your matrix cell column>
Product Order: G_Across G_Down1 G_Down2
Reset at: G_Across
- increase the vertical size of G_Across to make room for the new field
- increase the size of G_Down1 to fill up the space you've created
- increase the size of G_Down2 to fill up the space you created
- insert a field into this space (should be the matrix frame whose properties are:
Vertical Repeating Frame: G_Down2
Horizontal Repeating Frame: G_Across)
- bring up the property palette against the field and set the source to: CS_SubTotal
