Use this window to both register price lists and define 
sales prices within the price lists. A price list can be connected either to a 
customer or a project. A price list that is connected to a project has higher 
priority.
The columns available in the Price List window are based on the Sales Price 
Criteria defined for the company.
You can use the wildcard symbol (%) for the different columns in the window. 
When deciding which row to use for a given project transaction, distinct values 
have higher priority than wildcards, with columns defined with a lower 
Evaluation Order having higher priority.
