Group customers after how many years they have been customer

[#1]

Hi.

I have Revenue from 4 years and i want to group the customers after how many years they have had revenue.

If the customer have revenue i all 4 years the customer should be in Group "All 4 years", if the customer has revenue in 3 of the 4 years the group should be "3 years."

Can anyone tell me which function i have to use.

Best regards

Thomas
