Batch Number Completion

Hello,

I am trying to update existing PO with batch numbers, but when I run my code nothing is happening.

Here is an example with a single row:

Set bO = oCompany.GetBusinessObject(oPurchaseDeliveryNotes)

bO.GetByKey (22)

bO.Lines.SetCurrentLine (0)

bO.Lines.ItemCode = "0007"

bO.Lines.Quantity = 5

bO.Lines.BatchNumbers.SetCurrentLine (0)

bO.Lines.BatchNumbers.BatchNumber = 14600012

bO.Lines.BatchNumbers.Quantity = 5

bO.Lines.BatchNumbers.Add

lreturncode = bO.Update()

Thanks, any help would be appreciated!

RGDS,

Zsolt
