The special orders history list is grouped into 3 lists:
Incoming - This list would show all special order items that are contained within a purchase order or inventory batch but have not been linked to a sales order. This list should normally be blank unless the special order item is used for lots. Review the Using Special Orders to Track Lots section for more details.
Outgoing - This list would show all special order items that are entered into a sales order but are not purchased or linked to a purchase order. The list of all the special orders that are in this state are listed within the Special Orders tab of the purchasing window. Go to Inventory > Inventory Purchasing and click on the Special Orders tab.
Linked - This list would show all special orders that are linked between the purchase order and the sales order.

Use the Remove button to delete a detail line from the list. This option should not be used for items that contain purchase and sales invoices.
