Forum Post: Update Purchase Order line UDF during receipt of goods entry

I am trying to update a UDF in Purchase Order entry lines during a receipt of goods.  The issue I am having is that the purchase order record is locked while a receipt of goods / invoice records exist referencing the purchase order.    Here is the code I am using below.  I do not receive an error, but the PO line is not update.   Any direction would be greatly appreciated. editline = "" editline = oPOLines.GETEDITKEY(lineno) retval = oPOlines.editline(editline) if retval = 1 then     poitem = ""     retVal = oPOLines.GetValue("ItemCode$",poitem)     retVal = oPOLines.GetValue("UDF_QTY_INTRANSIT",intranqty)     intran = intranqty - QtyReceived     retVal = oPOLines.SetValue("UDF_QTY_INTRANSIT",intran)     retVal = oPOLines.SetValue("CommentText$","Justin was here")     retVal = oPOLines.Write()     if retval = 0 then         oui.messagebox(opolines.LastErrorMsg)     end if else     oui.messagebox(opolines.LastErrorMsg) end if I have also tried calling the child object, but not sure how to determine which child objects are available.  Here is the code I have tried, but do not find the child object: polineobj = 0 opolineobj = oROGLines.GetChildHandle("OrderLineKey")  ' opollineobj = 0 if opolineobj 0 then  '     Set opolineobj = oSession.AsObject(opolineobj) else     oui.messagebox("No opolineobj object") End if
