The orders can be partially received. If the sales order is partially delivered or billed, the Quantity delivered or billed is changed in the Quantity column when the Order Slip is transferred. In this case, a new transfer is made for the undelivered part of the order. 
When the transfer is made again for the undelivered part, the undelivered and delivered quantities are listed. If the undelivered part of the order will be closed or cancelled, the transaction must be performed using the Change Status option located in the right click menu of the order list. 
Slip statuses can be tracked on the status column of the sales order slip. If the remaining quantity will not be tracked as an undelivered order, the status is selected as Closed on the Status Change screen. Otherwise, the status is kept as Shipping until the undelivered quantity is delivered. 
Orders delivered in whole are automatically recorded as Closed. The reports list the Undelivered Orders and Closed Orders separately using the Delivery Status filter.
