Inventory Detail for Item Receipt

Hi,

I am having a problem of creating Item Receipt from a Purchase Order. The Item Receipt should have inventorydetail. But when I try it through nlapiTransformRecord function. An error prompt appears: itemReceipt.editCurrentLineItemSubrecord is not a function.


Here is my code.

var itemReceipt = nlapiTransformRecord("purchaseorder", 77, "itemreceipt");
//itemReceipt.setFieldValue("landedcostperline", "T");

for( var i = 1, lineCount = itemReceipt.getLineItemCount("item") ; i <= lineCount ; i++ ) {
itemReceipt.selectLineItem("item", i);

itemReceipt.setCurrentLineItemValue("item", "itemreceive", "T");

itemReceipt.setCurrentLineItemValue("item", "quantity", '200');
//itemReceipt.setCurrentLineItemValue("item", "rate", thisLinesRate );
var inventorydetail = itemReceipt.editCurrentLineItemSubrecord("item", "inventorydetail");
if( inventorydetail == null )
inventorydetail = itemReceipt.createCurrentLineItemSubrecord("item", "inventorydetail");
inventorydetail.selectNewLineItem("inventoryassign ment");
