Allows Promotions to be applied to Credit Memos and to credit items on Invoices. This option will allow a credit memo to calculate promotion credits based on a current running promotion, the date of the credit memo and other factors which determine if a promotion is qualified.

 

This system option will be useful if the original invoice included promotions and you need to provide the corresponding promotional credits on the customers credit memo.

 

For the purposes of applying quantity limits the "absolute value" of the item quantity will be used. This means that a -5 (negative 5) will be treated as 5.
