I have a dynamic report that shows income statement items trended out for the last 12 months.
If, for example, the user selects to see Gross Revenue and Cost Of Materials, these measures will be the row items and the months will be the column headers. I've hidden the detail section where each transaction is stored and display the sums of the measures in the "Measure" Group header.
This works great, but now I need to insert a row for Cost of Materials as a percent of Gross Revenue. How do I specify to divide COM by GR? Of course the data is just numbers and the computer doesn't understand that I want to divide one by the other.
I've tried the formula = sum([200808])/sum([200808]) where 200808 is the column name, but of course no matter what header or footer i place this in I just get 100%. Is there any possible way to accomplish what I need?
