Inventory Receipt Serial Numbers

Currently in Acumatica, when you are trying to receive an item with serial numbers from a 2 step transfer, the document already comes with the serial numbers from the original transfer.

I’ve tried to remove them from the Cache objects and views y different ways but ultimately it doesn’t work.  Is there a way to clear or remove all line details records when the Transfer number is selected? This way the user validates the physical serial number and enters it in the system.

Here is my code with all the ways I’ve tried. Any help will be much appreciated. 

protected void INRegister_TransferNbr_FieldUpdated(PXCache cache, PXFieldUpdatedEventArgs e)
        {

            var row = (INRegister)e.Row;
            // this.Base.Caches<PX.Objects.IN.INTranSplit>().Clear();
            //this.Base.Caches<PX.Objects.IN.INCostStatus>().Clear();
            // this.Base.Caches<PX.Objects.IN.Overrides.INDocumentRelease.ItemLotSerial>().Clear();
            //this.Base.Caches<PX.Objects.IN.INItemPlan>().Clear();
            //this.Base.Caches<PX.Objects.IN.Overrides.INDocumentRelease.LotSerialStatus>().Clear();
            //this.Base.Caches<PX.Objects.IN.Overrides.INDocumentRelease.SiteLotSerial>().Clear();

            //foreach (var d in Base.Caches< PX.Objects.IN.INTranSplit>().Cached)
            //{

            //    Base.splits.View.Cache.Delete(d);
            //}

              //this.Base.splits.View.Cache.Clear();

            // this.Base.splits.View.RequestRefresh();
            //this.Base.Caches.Clear();

            //foreach(INTranSplit sp in Base.splits.Select())
            //{
            //    Base.splits.Delete(sp);
            //    //Base.splits.UpdateCurrent();
            //}



            // this.Base.splits.Cache.Clear();
            //this.Base.splits.Cache.Clear();
            //this.Base.splits.View.RequestRefresh();

        }
