Promised items

A promised order line is a demand line for which a scheduled shipment date has been promised based on Available to Promise (ATP) calculations of future supply and demand. Quantity for promised items is not soft-reserved or allocated (subtracted from the business unit or material storage location's available quantity) until the demand line has been allocated by the Order Release process or confirmed as picked by the Picking Confirmation process. You can promise items marked for ATP processing using a reservations process.

Orders can be released directly from an unfulfilled state, bypassing the reservations process. ATP items released in this manner are promised and released if inventory is available at the material storage location level. Normal ATP rules are not followed as this is considered an exception situation.
