The calculation basis can be performed:

• 'by Unit', which means that the column amount is a unit amount applied to the sales unit entered.
  It will thus be multiplied by the quantity.
   
• 'by Line', which means that the column amount is a fixed amount for the line.
   
• 'by Document', which means that it is a column that is added up in the invoice footer and for which price setting rules by line group exist (for example the discount amount based on the invoice total). The principle of this calculation basis is linked to the use of grouped price lists.
   
  For instance :
  If, in a grouped price list, rules for the application of a charge have been defined, for example: for an invoice whose total amount is greater than €1,000, 10% of carriage charges will be applied.
  The Carriage charges column is defined in the structure code with a calculation basis By Document and the attached invoicing element is Footer carriage charges. If the total amount of the invoice is greater than €1,000, €100 of carriage charges will be calculated for footer Footer carriage charges. The price list column Carriage charges can be used for the entry of amounts (or percentage according to the setup) that will impact the net price of the line and thus will be independently posted on the lines.
  This setup is used to combine specific grouped price list terms directly on a footer, while keeping the possibility to use the column for another charge or discount that can be entered on the line.

 In the case of percentages, the percentage calculation is made only by unit.
