I have two calculated pivot tables as:
Marketing Channel OrderMonth (Jan 2016, Feb 2016....)
First Marketing Channel FirstOrderMonth (Jan 2016, Feb 2016....)
The first table has the count of all the customers by month and by channel
The second table has the count of all the NEW customers by month and by first channel
I would like to have a table that divides the second table by the first table, so I know the % of new, but these tables are based on different dimensions.
