Rescheduling Sales Documents 
Rescheduling Sales Documents
Purpose
With the help of this report you can retransfer all open requirements for a material per plant to the availability check.
Controllable Sorting of Documents
The availability check basically processes requirements according to a strict FIFO principle. That means that the date on which the order item was created is decisive.
With rescheduling you can influence in which sequence the system should arrange the requirements along the time line by using sort criteria such as the requested delivery date or delivery priority.
When you create a sales document, the system checks if the current requirement can be fulfilled in the requested quantity for the requested delivery date. Depending on the scope of check setting, it checks already existing stock and future incoming stock on the one hand, and then checks already posted and therefore stock-reducing sales documents on the other hand.
The stock-reducing documents are in this case all requirements records from open sales documents whose entry dates are in the past, independent of whether the sold-to party should receive the delivery immediately or not for a few weeks.
Consequently, requirement A, for example, which was entered relatively early on but whose delivery is not to take place for a few weeks, has been fully confirmed by the availability check. Requirement B, however, which was entered at a later date but whose goods are needed as fast as possible, could only be partially confirmed or not at all.
If you execute rescheduling with sorting according to the requested delivery date, the availability check will run for requirement B first. If there is enough stock, the availability check will fully confirm the requested quantity for the original requested delivery date. Depending on the amount of stock still available and/or the amount and date of the planned incoming stock, requirement A can also be confirmed for the requested delivery date.
Consideration of Change Quantities and Deadline Changes with Incoming Stock
If deadline changes occurred with the incoming stock, for example, if your vendors deliver the ordered goods at a later time or if production orders cannot be fulfilled for the originally targeted date, you can adjust the delivery dates in your sales documents by using rescheduling.
When creating a sales order, the availability check confirms the requirement in the requested quantity for the requested delivery date based on incoming stock that exists in the form of a purchase order. You post the document. Subsequently, you find out that your vendor will not be able to deliver the purchase order until 10 days later.
It is therefore no longer possible to deliver the requirement on time. However, since there is no fixed relation between the delivery date that has been confirmed for a requirement and the delivery date of the purchase order, the system does not automatically adjust the delivery date in the sales order.
Changes in stock such as these are taken into consideration during rescheduling. If requirements have delivery dates for which the availability check cannot find suitable incoming stock, their delivery dates and delivery quantities will be adjusted. If the corresponding setting has been made in the availability check, the documents will be confirmed for the date of the next incoming stock.
