Backorder Processing

Use

Backorder processing can be used to check material availability when the demand or supply situation in your sales order fulfillment process has changed and you want to check if previously calculated confirmations for sales orders are still realistic. For example:

A sales order is canceled, thereby freeing up stock quantities.
An important customer increases the requested quantity for a material and would therefore like to consume stock which is currently confirmed for other sales orders.
A planned supply (production order) is running late.

Not reacting to the changed availability situation can result in confirmed quantities exceeding available quantities. This can result in availability checks for over-confirmed materials failing, leaving you unable to release materials for delivery creation.
