You can use any of the following programs to delete an SO or SO line:

When a sales order line is deleted, the system deletes the booked or new serial IDs linked with the sales order line. If the booked or new serial IDs also link a work order, the system removes the link between the work order and the serial IDs. If they are imported serial IDs, they remain in the import list of serial IDs and the system sets the Used field to No for them. The system also creates serial history records with Type, Begin Quantity, Quantity Change and Stage being PCK-DEL/SER-DEL, Zero, Zero, and Blank respectively.

You cannot delete an SO (or customer scheduled order) line when there are picked serial IDs attached to the line. When you try, the system displays an error message. Also, when there are consumed serial IDs—including serial IDs aggregated on a consumed pack— that are attached to a returned shipper, the system displays an error message when you attempt to delete the shipper sales order line.

You can use the Shipping History browse to view shipping history after you delete sales orders. Once you delete the SO/order line and the shipper, you can still view shipping history data to look up which pack/item was shipped for an SO line and shipper. See Tracking and Tracing Shipping Data.

When you delete an SO or SO line, all quantities ship, and the invoice posts, the system deletes the relationship to the serial ID. Likewise, when you delete all SO lines on the shipper, the system deletes the serial ID relationship to the shipper.

You can still return serialized items once you delete the SO. To do this task, you create another sales order with a negative quantity to return the pack, using the standard EE SO maintenance programs. The system verifies the shipping history to ensure that the serialized pack or item is consumed by the confirmed SO shipper and not yet returned.

When you return serialized items, or unit or assembly packs with a single item, and enter the SO line with a negative quantity, make sure that you specify the same ship-from and ship-to as the deleted SO. You use the same programs for an SO return; that is, use Pre-Shipper/Shipper Picking to pick the consumed serial IDs and Pre-Shipper/Shipper Confirm to confirm the return transaction.

When you return an assembly pack with multiple items, the system displays an error in the SO maintenance program and prompts you to enter each lower-level pack with single item to do the return.

Once you delete the SO, verify that serial data that ships for this sales order is correct in the browses and browse collections:
