Is there a way to stop the order notes being copied to the shipment notes automatically on Create Shipment?

Hi @ppowell ,

As @Laura02 suggested, you have to customize the Create Shipment actions. Following is the customization you can try,

  public class SOOrderEntry_Extension : PXGraphExtension<PX.Objects.SO.SOOrderEntry>
  {
    #region Event Handlers
		public delegate IEnumerable CreateShipmentIssueDelegate(PXAdapter adapter, Nullable<DateTime> shipDate, Nullable<Int32> siteID);
		[PXOverride]
		public IEnumerable CreateShipmentIssue(PXAdapter adapter, Nullable<DateTime> shipDate, Nullable<Int32> siteID, CreateShipmentIssueDelegate baseMethod)
		{
            PXGraph.InstanceCreated.AddHandler<SOShipmentEntry>((graphShipmentEntry) =>
            {
                graphShipmentEntry.RowPersisting.AddHandler<SOShipment>((sender, e) =>
                {
                    sender.SetValue<SOShipment.shipmentDesc>((SOShipment)graphShipmentEntry.Document.Current, "");
                });
            });
            return baseMethod(adapter,shipDate,siteID);
		}
    #endregion
  }

Hope that help and Good Luck,
