Field help (CPYPLISTC) 

This field is used to enter a price list structure code.
This code determines the commercial conditions managed for each sales transaction line ('Discount and Charge' field) for the current company.
A sales structure code can be shared by one or several companies. Two companies that share a single price list structure will be authorized to share the same price list.
It is necessary to have a structure code for a company. If an "empty" structure code is created, it will be automatically associated to each created new company.
SEEWARNING When a price list structure is changed, the new structure must include the previous one.
