Track first time usage of a product by a customer

[clivebredenkamp]

Hi,

I would like to track the first time uptake of a product by a customer in a given year e.g. 2018. The idea is to see what volumes are coming in for a product for the first time from a customer. In other words what volume of transactions in 2018 is due to new sales.

Source data

Company CompanyID Product TransactionDate

ABC	1	ProdA	2017/01/17
ABC	1	ProdB	2018/02/03
ABC	1	ProdC	2017/03/01
XYZ	2	ProdA	2017/02/01
XYZ	2	ProdA	2017/03/01
XYZ	2	ProdA	2017/04/01
DEF	3	ProdC	2018/03/01
DEF	4	ProdB	2018/04/01

Desired Results

Product FirstTimeUsage2018

ProdA	0
ProdB	2
ProdC	1

Any help would be appreciated.
