Creating periods and link last order dates per customer

Wed, 04 Jan 2012 12:52:43 GMT

Hi,

I am trying to create period for the last order date of customers.

Customers may have mulitple pruchases or may not have purchased anything in the periods noted below. Only the last order date per customer is relevant.

The periods are spanning two years:

Period,StartYear,EndYear

1,2000,2001

2,2002,2003

3,2004,2005

4,2006,2007

5,2008,2009

I need to use the values of those periods in a calculation.

First of all how do I get the last order date per customer and how do I then link that to the periods above?

Thanks for your help,

Peter
