Enter the number of days that are subtracted from a requirement due date. This number defines a time interval during which a planned receipt that is due can be used to fulfill the requirement. A planned receipt that is outside the defined time interval cannot be used to fulfill the requirement. Master scheduling generates a new planned order. You can equate positive days with the number of days that you can use existing inventory before you must create a new fulfillment order. For items that you regularly order and procure, specify the item's coverage period as positive days. For items that have few transactions, specify the coverage group's coverage period as positive days.You can specify positive days in either the Item coverage page or the Coverage groups page. For example, for a particular item, there is inventory, and a sales order is scheduled for delivery in 90 days. If you enter a number that is less than 90, a new planned purchase order is generated. If you set the positive days to a number that is more than 90, no planned purchase order is generated. However, the current inventory levels of the item are no longer available for new sales orders.
