Problem with SerialNumbers with 2007 PL 47: BOM in documents does not work

Hi everybody.

I have the following problem: i need to create documents through DI API (2007 PL 47).

The items in document are BOM (sale type) with just one item as a child: this item child is managed with serial numbers.

When i try to create a delivery notes with DI API, i receive the following error:

"Found error:-10,You should use existing serial/batch numbers for this document type [(----) 29-51]".

The following code (VB . NET) is used for the insertion of the delivery (just one line with only one item BOM, with only one item child):

Dim nErr As Long

Dim errMsg As String = ""

Dim delivery As SAPbobsCOM.Documents

Dim deliveryLines As SAPbobsCOM.Document_Lines

Dim serialNumbers As SAPbobsCOM.SerialNumbers

delivery = oCompany.GetBusinessObject(BoObjectTypes.oDeliveryNotes)

delivery.DocObjectCode = BoObjectTypes.oDeliveryNotes

delivery.CardCode = "C0020"

delivery.DocDate = Today

delivery.DocDueDate = Today

delivery.TaxDate = Today

' CREATE A LINE WITH BOM

deliveryLines = delivery.Lines

deliveryLines.SetCurrentLine(0)

deliveryLines.ItemCode = "GARANZIA"

deliveryLines.WarehouseCode = "Mc"

deliveryLines.Quantity = 1

' ASSIGN A SERIAL NUMBER RELATED WITH CHILD ITEM IN A BOM

serialNumbers = deliveryLines.SerialNumbers

serialNumbers.SetCurrentLine(0)

serialNumbers.SystemSerialNumber = 2

delivery.Add()

oCompany.GetLastError(nErr, errMsg)

If (0 <> nErr) Then

MsgBox("Found error:" + Str(nErr) + "," + errMsg)

End If

Obviously the SystemSerialNumber used is available in a warehouse.

The process, through the BOne interface, work correctly.

The same code work correctly with the 2007 PL 42, but does not work with the 2007 PL 49.
