This field indicates whether the quantity of the trigger code is linked to the quantity of the trigger line (applies to Trigger Function Item only).
For example, a selected item has quantity 2 (the trigger line).
 The item triggers this infocode selection. The result of selecting this subcode is an item line with quantity 2. 
Note - If the infocode is marked Link Item Lines to Trigg. Line, the Quantity Handling of the infocode controls the quantity of the infocode item line.
