Searching customer purchase history in Receipt screen is faster than searching within Customer screen. But you will not be able to see total amount of all purchases for the customers doing this way. If there are too many same last name, it will be hard to find.
This is a workaround solution
1. Click on RECEIPT button
2. Enter Customer's Last name and press Enter. Click on DATE RANGE button on the right panel
3. Select UNDEFINED and click OK
4. you will be able to see all purchase under customer's last name
