You can now define conditions that only apply when the prerequisites and requirements you define are met. For example, you offer a reduced price when a customer buys certain quantities of particular materials together or when a credit card is used for payment.
Prerequisites can be items that have to be in a transaction in addition to the subject of the condition (for example, a prerequisite might be the purchase of other materials or the redemption of a coupon).
Requirements refer to the total sale in general or other aspects of the sale (such as a minimum sale or payment by customer card).
You can enter a particular number of a single material or group together any materials of your choice in any quantities of your choice as prerequisites. The subject of the condition can also be a single material, a group of materials, all the prerequisites or even the whole transaction.
Conditions can be special prices, fixed discounts, percentage discounts or free-goods discounts. You can also define scales for the bonus buy condition.
A distinction is made in R/3 between the following types of bonus buy:
You can transfer the prerequisites, requirements and conditions for bonus buys to the POS systems (see Release Information POS Interface-Outbound: Integration of Bonus Buys).
At POS inbound processing, R/3 posts the bonus buys at the special conditions (see Release Information POS Interface-Inbound: Integration of Bonus Buys).
For further information on bonus buy conditions, see the SAP Retail documentation (SAP library -> Logistics -> SAP Retail) under Master data -> Conditions.
