In receipt based schedules, the supplier's position is taken into account. As a result, in case of an underdelivery, schedule lines with a planned requirement date that falls before the next schedule issue date are inserted as immediate requirements in the Purchase Release Line - Details (tdpur3522m000) session.

Order based schedules are independent of the supplier's position. In case of an overdelivery or underdelivery, suppliers are responsible for calculating their positions in relation to the demand.
