Averages in a Subsummary Report
I have a part defined subsummary report layout. All the orders are grouped by month, and display the total sales for each month. I need to also display the daily averages per month. How can I make it part of the subsummary report? I was thinking to create a new field that would add all the orders of the same month and then divide by number of days in the month. However I don't know what to put in the calculation field.
Is there a better alternate solution?
