How to calculate the difference of two columns in crosstab report
hmmm. This may be a trick question, but I will play along...
Creating a new data item (col3) with a definition of col1-col2 doesn't work?
What happens when you use this calc? What is your data source, i.e. Relational, Dimensional?
Dimensional
make sure the solve order on col3 is set to a higher numer than that of col's 1&2. You will find solve order in the properties pane of the col3 header.
No this is not working...
