Once the option is enabled, the system will show the Price List drop-down menu to choose a price list. Choose the customer and the system will select by default the price list associated to the customer (and location if applies) from theCustomers Setup.
In any case, the system will allow you to choose other price lists (type All and Prebook) and will apply it to products added to the Prebook.
Tip
It is possible to select a different price list for each product line within a Prebook.
