In SAP Business One, you can have two types of blanket agreements:

• General blanket agreements: Are used to track fulfillment of terms to obtain a special bonus at year end, for example, for selling or purchasing a certain quantity of an item or for achieving a defined turnover.
• Specific blanket agreements: Are used to track fulfillment of terms to obtain a special discount for the individual sales or purchasing transaction. They are also used to determine a delivery schedule, for example, by defining at which intervals which quantity of goods should be delivered.
