Hi, I'm trying to generate a market product penetration report to see what customers in my data who principally buy a product and also buy other products along with it. For example, below is report I want to generate and I want to establish the item penetration of a customer. In the given example, out of 20 customers who bought beer, 5 bought crisps, 3 bought fries, 1 bought soda, 1 bought mineral water and 1 bought fast food. Can anybody please suggest me a procedure or a way to generate this kind of a report?
|Customers||Beer||Crisps||Fries||Soda||Mineral Water||Fast food|

Can anybody help?
