Criteria.
If Customer has a sales value > 0 in each of the last 3 months set to A.
If Customer has a sales value > 0 in each of the last 6 months set to B.
If Customer has a sales value > 0 in each of the last 9 months set to C.
I'm open to any ideas to classify this?
I'm thinking I need to do this as part of the load and assess 'InMonthtoDate' into a summarised table somehow.
