How do I reference SOOrder when trying to default a field in SOShipmentEntry?

I am trying to get the unpaid balance to automatically be entered by default when adding a new package on the Shipments screen.  We need to do this only for records where Payment type is COD.  How do I reference SOOrder when modifying the value in SOPackageDetailEx?

I have the following code:

<Code snipped>

Basically we just need the bit where I am inserting 20.0 to be changed to insert the value held in SOOrder.UnpaidBalance instead if SOOrder.PaymentMethodID = ‘COD’. I’m not sure how to reference SOOrder from here. I have been going through the Acumatica training regarding customizations but this is still beyond me.

Thanks for any help,

Phil

Hi @ppowell 

The unpaid balance is a calculated field on the soscreen and the value is not stored in DB. We need to write logic and get the unpaid balance.

Please try like below and check the value you are getting correctly. If not working, adjust the code based on your requirement.

        #region Event Handlers

        protected void SOPackageDetailEx_COD_FieldDefaulting(PXCache cache, PXFieldDefaultingEventArgs e, PXFieldDefaulting InvokeBaseHandler)
        {
            if (InvokeBaseHandler != null)
                InvokeBaseHandler(cache, e);
            var row = (SOPackageDetailEx)e.Row;
            if (row == null) return;

            SOShipLine item = Base.Transactions.Select().FirstOrDefault();
            if (item != null)
            {
                SOOrder order = PXSelect<SOOrder, Where<SOOrder.orderNbr, Equal<Required<SOOrder.orderNbr>>, And<SOOrder.orderType, Equal<Required<SOOrder.orderType>>>>>.Select(Base, item.OrigOrderNbr, item.OrigOrderType);
                e.NewValue = GetUnpaidBalance(order);
            }
        }
 

        public decimal? GetUnpaidBalance( SOOrder order)
        {
            decimal? creditMemo = 0;
            decimal? payment = 0;

            foreach (SOAdjust objSoadjust in PXSelectJoin<SOAdjust, InnerJoin<ARPayment, On<ARPayment.docType, Equal<SOAdjust.adjgDocType>, And<ARPayment.refNbr, Equal<SOAdjust.adjgRefNbr>>>>,
                                        Where<SOAdjust.adjdOrderNbr, Equal<Required<SOAdjust.adjdOrderNbr>>, And<SOAdjust.adjdOrderType, Equal<Required<SOAdjust.adjdOrderType>>>>>.Select(Base, order.OrderNbr, order.OrderType))
            {
                if (objSoadjust.AdjgDocType == ARDocType.Payment)
                {
                    payment += objSoadjust.CuryAdjdAmt + objSoadjust.CuryAdjdBilledAmt;
                }
                if (objSoadjust.AdjgDocType == ARDocType.CreditMemo)
                {
                    creditMemo += objSoadjust.CuryAdjdAmt + objSoadjust.CuryAdjdBilledAmt;
                }
            }

            foreach (ARAdjust objARAdjust in PXSelectJoin<ARAdjust,
                               InnerJoin<ARPayment, On<ARPayment.docType, Equal<ARAdjust.adjgDocType>, And<ARPayment.refNbr, Equal<ARAdjust.adjgRefNbr>>>,
                               InnerJoin<SOOrderShipment, On<SOOrderShipment.invoiceType, Equal<ARAdjust.adjdDocType>, And<SOOrderShipment.invoiceNbr, Equal<ARAdjust.adjdRefNbr>>>>>,
                               Where<SOOrderShipment.orderNbr, Equal<Required<SOOrderShipment.orderNbr>>, And<SOOrderShipment.orderType, Equal<Required<SOOrderShipment.orderType>>,
                               And<ARAdjust.adjdOrderNbr, IsNull, And<ARAdjust.adjdOrderType, IsNull>>>>>
                              .Select(Base, order.OrderNbr, order.OrderType))
            {

                if (objARAdjust.AdjgDocType == ARDocType.Payment)
                {
                    payment += objARAdjust.CuryAdjdAmt;
                }
                if (objARAdjust.AdjgDocType == ARDocType.CreditMemo)
                {
                    creditMemo += objARAdjust.CuryAdjdAmt;
                }
            }

            return order.OrderTotal - creditMemo - payment;
        }
