Screen based API creation of PO receipt from POLin

We are trying to add PO lines to the receipt document using 'ADD PO LINE' smartpanel. Below is the code, but it always chooses the first 2 lines instead of the keys specified in the command.

//select lines from smart panel
foreach (POReceiptLine line in POReceiptlines.OrderBy(x => x.LineNum))
{
    AcumaticaInterface.apitest.Command[] Docline = new AcumaticaInterface.apitest.Command[]
                {                     
                    new Key
                    {
                        ObjectName = PORcptSchema.AddPurchaseOrderLine.OrderNbr.ObjectName,
                        FieldName = PORcptSchema.AddPurchaseOrderLine.OrderNbr.FieldName,
                        Value = "='" + line.BaseDocNum + "'",
                        Commit =true
                    },
                    new Key
                    {
                        ObjectName = PORcptSchema.AddPurchaseOrderLine.LineNbr.ObjectName,
                        FieldName = PORcptSchema.AddPurchaseOrderLine.LineNbr.FieldName,
                        Value = "='" + line.BaseLineNum + "'",
                        Commit =true
                    },              
                    new Value 
                    {
                        Value = "True", 
                        LinkedCommand = PORcptSchema.AddPurchaseOrderLine.Selected, 
                        Commit = true 
                    }  
                };
                Document = Document.Concat(Docline).ToArray();
            }

    // Add PO line and retrieve back the added lines.
    var addPOLine = new Command[]
                        {                             
                            addPOLineWithCommit,
                            ////get back the added lines in the grid
                            PORcptSchema.DocumentDetails.POOrderNbr,
                            PORcptSchema.DocumentDetails.POLineNbr
                        };
            Document = Document.Concat(addPOLine).ToArray();

            var receiptLines = context.PO302000Submit(Document);

We are trying to select the lines of order Nbr '000014' [Line Nbr(1,2)], but the lines added are of Order Nbr '000012' [Line Nbr(1,2)]. Please assist.

The solution is to clear LinkedCommand set by default for the AddPurchaseOrderLine.Selected field:

receiptSchema.AddPurchaseOrderLine.Selected.LinkedCommand = null;

Below is the complete SOAP request, that allows to locate and select records on the Add Purchase Order Line popup via the Screen-Based API:

Content receiptSchema = context.GetSchema();

receiptSchema.Actions.AddPOOrderLine.Commit = true;
receiptSchema.Actions.AddPOOrderLine2.Commit = true;

receiptSchema.AddPurchaseOrderLine.Selected.LinkedCommand = null;

var commands = new Command[]
{
    new Value
    {
        Value = "Receipt",
        LinkedCommand = receiptSchema.DocumentSummary.Type
    },

    new Value
    {
        Value = "PR000416",
        LinkedCommand = receiptSchema.DocumentSummary.ReceiptNbr
    },

    new Value
    {
        Value = "OK",
        LinkedCommand = receiptSchema.AddPurchaseOrderLine.ServiceCommands.DialogAnswer,
        Commit = true
    },

    receiptSchema.Actions.AddPOOrderLine,

    new Key
    {
        ObjectName = receiptSchema.AddPurchaseOrderLine.OrderNbr.ObjectName,
        FieldName = receiptSchema.AddPurchaseOrderLine.OrderNbr.FieldName,
        Value = "='PO000483'"
    },
    new Key
    {
        ObjectName = receiptSchema.AddPurchaseOrderLine.LineNbr.ObjectName,
        FieldName = receiptSchema.AddPurchaseOrderLine.LineNbr.FieldName,
        Value = "='1'"
    },
    new Value
    {
        Value = "True",
        LinkedCommand = receiptSchema.AddPurchaseOrderLine.Selected
    },

    new Key
    {
        ObjectName = receiptSchema.AddPurchaseOrderLine.OrderNbr.ObjectName,
        FieldName = receiptSchema.AddPurchaseOrderLine.OrderNbr.FieldName,
        Value = "='PO000483'"
    },
    new Key
    {
        ObjectName = receiptSchema.AddPurchaseOrderLine.LineNbr.ObjectName,
        FieldName = receiptSchema.AddPurchaseOrderLine.LineNbr.FieldName,
        Value = "='2'"
    },
    new Value
    {
        Value = "True",
        LinkedCommand = receiptSchema.AddPurchaseOrderLine.Selected
    },
    receiptSchema.Actions.AddPOOrderLine2,

    receiptSchema.Actions.Save
};
