Field help (FOCQTYBKT) 

This field can be initialized according to the price list setup, Price/Free tab.
This field is displayed if, during the price list code setup, the free item type is defined as "Multiple".

This is the class based on which free products are assigned, when the minimum quantity for assigning free products is respected. The number of free products is determined with respect to the number of occurrences of the class and to the free item quantity (number of classes x number of free products).
The value corresponding to a class is in the price list currency.
The threshold value is used only in the grouped price lists which are applied with respect to the document value (gross prices or net prices).

Example 1 :
In a price list record is defined:
- Free item minimum: 8
- Free item class: 2
- Free item quantity: 1

Example 2 :
In a price list record is defined:
- Free item minimum: 10
- Free item class: 5
- Free item quantity: 2
