Default Sales Order Shipment Quantity to 0

Hi ​@AJohnson 

Please use below code snippet to make it work as expected.

public delegate void CreateShipmentDelegate(CreateShipmentArgs args);
[PXOverride]
public void CreateShipment(CreateShipmentArgs args, CreateShipmentDelegate baseMethod)
{
    // Call the original method
    baseMethod(args);

    // Ensure all transaction lines have 0 quantity
    foreach (SOLine line in Base.Transactions.Select())
    {
        SOLine updatedLine = Base.Transactions.Cache.CreateCopy(line) as SOLine;
        if (updatedLine != null)
        {
            updatedLine.BaseQty = 0;
            updatedLine.Qty = 0;
            updatedLine.ShippedQty = 0;
            updatedLine.BaseShippedQty = 0;

            Base.Transactions.Update(updatedLine);
        }
    }

    foreach (SOLineSplit split in Base.splits.Select())
    {
        SOLineSplit updatedSplit = Base.splits.Cache.CreateCopy(split) as SOLineSplit;
        if (updatedSplit != null)
        {
            updatedSplit.Qty = 0;
            updatedSplit.BaseQty = 0;

            Base.splits.Update(updatedSplit);
        }
    }

    // Save changes
    Base.Actions.PressSave();
}

Hope this helps
