A typical way to use Line Discount Offer is to use it to control how much discount to give when item is damaged in some way. By creating a Discount group and setting up discounts in the group to cover all possible and acceptable discounts for damaged items, it is possible to have a range of offers covering each category of the operation or even one offer covering everything. After creating and setting up the offer the only thing needed is to define a button on the POS to activate the selection of the best offer within a given Line Discount Group.
To do so, use POS command LINE_DISC_OFFER and the line discount group as parameter.
Note: This only describes how line offers are calculated as such. The final outcome will depend on how Line Discount Offers interact with other offers and the discount sequence calculation where combination of sequence and calculation functions can affect the final outcome.
