Hi,
I have a huge database of our sales to customers for the last 7 years classified by "Year" in Columns and "Customer" in Rows.
I need something to look on the sales trend, for example:
- Customers who stopped buying for the last 2 years
- Customer sales that was dropped by more 50% for the last 2 years
I am thinking of something to compare 2010 sales with 2011, then 2011 with 2012 and so on !!
Is it possible?
Thanks,
Islam
