ToLocationID field not found in POReceiptLineSplit data class

Can you show me the screen you inspected the element above on?

In Put Away mode on this screen:

This appears to be related to WMS and specifically screen PO302020.  First some technical “digging” and then I’ll try to explain.

Technical Details

According to the ASPX page, this screen uses PX.Objects.PO.WMS.ReceivePutAway+Host.  

<px:PXDataSource ID="ds" runat="server" Visible="True" Width="100%" TypeName="PX.Objects.PO.WMS.ReceivePutAway+Host" PrimaryView="HeaderView">

PutAwayMode.cs contains the following which looks like it probably is the right spot in code, although admittedly, this isn’t something I’m familiar with.

using WMSBase = WarehouseManagementSystem<ReceivePutAway, ReceivePutAway.Host>;

public partial class ReceivePutAway : WMSBase
...

According to PutAwayMode.cs, it looks like ToLocationID from INTran is programmatically added to POReciptLineSplit by way of some more fancy code.

public class ToLocationID : FieldAttached.To<POReceiptLineSplit>.AsInteger
...
var links =
	SelectFrom<POReceiptSplitToTransferSplitLink>.
	InnerJoin<INTran>.On<POReceiptSplitToTransferSplitLink.FK.TransferLine>.
	Where<POReceiptSplitToTransferSplitLink.FK.ReceiptLineSplit.SameAsCurrent>.
	View.SelectMultiBound(Base, new[] { row })
	.AsEnumerable()
	.Cast<PXResult<POReceiptSplitToTransferSplitLink, INTran>>()
	.ToArray();
...
state = PXFieldState.CreateInstance(
	value: state.Value,
	dataType: typeof(string),
	isKey: false,
	nullable: null,
	required: null,
	precision: null,
	length: null,
	defaultValue: null,
	fieldName: nameof(INTran.toLocationID),
	descriptionName: null,
	displayName: state.DisplayName,
	error: null,
	errorLevel: PXErrorLevel.Undefined,
	enabled: false,
	visible: Base.WMS.Header.Mode == PutAwayMode.Value,
	readOnly: true,
	visibility: PXUIVisibility.Visible,
	viewName: null,
	fieldList: null,
	headerList: null);
return state;

Short Version

Ok, so using these breadcrumbs, you want to add the DAC’s POReceiptSplitToTransferSplitLink and INTran.

POReceiptSplitToTransferSplitLink contains:

[CompanyID]
,[ReceiptType]
,[ReceiptNbr]
,[ReceiptLineNbr]
,[ReceiptSplitLineNbr]
,[TransferDocType]
,[TransferRefNbr]
,[TransferLineNbr]
,[TransferSplitLineNbr]
,[Qty]

You will link POReceiptLineSplit to POReceiptSplitToTransferSplitLink by the Receipt* fields and then connect INTran via the Transfer* reference fields.  This is when you should be able to use INTran.ToLocationID that you need.
