hi @SulayVargas51 ,

We had similar kind of implementation where we are copying soline notes to shipment line.
you can refer the below sample code and implement in your graph.

public delegate void CreateShipmentDelegate(CreateShipmentArgs args);
        �PXOverride]
        public virtual void CreateShipment(CreateShipmentArgs args, CreateShipmentDelegate baseMethod)
        {
            baseMethod(args);
            SOOrder orderData = args.Order;
            if (orderData != null)
            {
                SOOrderEntry soGraph = PXGraph.CreateInstance<SOOrderEntry>();

                foreach (SOShipLine line in Base.Transactions.Select())
                {
                    SOLine objLine = PXSelect<SOLine, Where<SOLine.orderNbr, Equal<Required<SOLine.orderNbr>>,
                                                  And<SOLine.orderType, Equal<Required<SOLine.orderType>>,
                                                  And<SOLine.inventoryID, Equal<Required<SOLine.inventoryID>>,
                                                  And<SOLine.lineNbr, Equal<Required<SOLine.lineNbr>>>>>>>
                                                 .Select(Base, line.OrigOrderNbr, line.OrigOrderType, line.InventoryID, line.LineNbr);
                    if (objLine != null)
                    {
                        soGraph.Transactions.Current = objLine;
                        PXNoteAttribute.SetNote(Base.Transactions.Cache, line, PXNoteAttribute.GetNote(soGraph.Transactions.Cache, soGraph.Transactions.Current));
                        Base.Transactions.Cache.Update(line);
                    }
                }
                Base.Actions.PressSave();
            }
        }


Hope this is Helpful.

Thanks very much !!
