subtracting period columns in a matrix
Hello All
I have been working in a simple report where i list sales.
In the rows I have the regions and vessel calls and in the columns I have the sales for 2006, 2005, 2004 and so forth.
My problem is that I have not found how to include a column showing the difference between a year and its prior year.
Can anyone help me on this.
Thnaks in advance and best regards,
