Hi Jakub,
Here's what you need to do:
1) While in the Preview Mode, right-click the header cell of the first column in the crosstab (In the example above, it is the January 2011 column) > Select Calculated Member > Insert Column.
A blank column with zero values is inserted.
2) Right-click the header cell of this Blank Column and select Calculated Member > Edit Header formula and type in this text:
"Subtotal"
3) Right-click the header cell again and select Calculated Member > Edit Insertion Formula. Type in this code:
GetColumnGroupIndexOf(CurrentColumnIndex) = 1
AND
( if CurrentColumnIndex <> GetNumColumns - 2 then Year(GridRowColumnValue("Date")) <> Year(GridRowColumnValue("Date", CurrentColumnIndex + 1)) else Year(GridRowColumnValue("Date")) = Year(Maximum({Date})) AND Month(GridRowColumnValue("Date")) = Month(Maximum({Date}))
)Note: In the above code, replace "Date" with the Date field used as Column in the Crosstab. The double-quotes are necessary and make sure to remove any parenthesis that CR automatically adds when a field is used in a formula.
Similarly, in the part where it reads Year(Maximum({Date})), replace {Date} with the Date field in the Crosstab however, this time use the parenthesis as in the code.
This should insert the Subtotal Column before a new year starts.
4) Next, right-click one of the zero values in the Subtotal column > Calculated Member > Edit Calculation Formula and use this code:
local currencyvar x;
local numbervar i;
local numbervar cindex := CurrentColumnIndex;
for i := 0 to cindex-1 do
( if year(GridRowColumnValue("Date",i)) = year(GridRowColumnValue("Date",cindex-1)) then x := x + GridValueAt(CurrentRowIndex, i, CurrentSummaryIndex);
);
x;Let me know how this goes.
