Error while entering Inventory Details using Script on Item Receipt.

HI All,

I am trying to create a Item Receipt from PO. While i am entering the Inventory Details on the Sub Record . It gives me error that Enter the Value of Serial/Lot Number which i am already adding in Script.

Below in my code.

    var NBRReceipt = nlapiTransformRecord('purchaseorder', '4001', 'itemreceipt', {recordmode: 'dynamic'});
   
    for(var i=1;i<=NBRReceipt.getLineItemCount('item');i++){
        NBRReceipt.setLineItemValue('item','itemreceive', i, 'F');
    }
    var InventoryDetail = ['BP1029t63','BP1029t64'];
    for(var i=1;i<=NBRReceipt.getLineItemCount('item');i++){
        if(NBRReceipt.getLineItemText('item', 'item', i)=='Beneficiary - Global'){
            NBRReceipt.selectLineItem('item', i);
