Serial number problem (again :)

Question

Hello everybody
My task is to create a goods receipt whenever a delivery is created and also to create a goods issue whenever a returns is created. Since, the creation of the goods receipt and the goods issue are identical i am using the same method. The problem is that it works fine when items are not managed by serial numbers, but when managed by sn-s,  the goods receipt is created correctly, when it comes to the goods issue it gives me the following error message: 
{IGE1.WhsCode]{line: 1], 'Item 'serial         ' with system serial 0 is not in stock
where "serial" is the item code
Do you have any idea what might be the problem?
thanks

public void createGoodsIssue()
    Documents oGoodsIssue = (Documents)B1Connections.diCompany.GetBusinessObject(BoObjectTypes.oInventoryGenExit);
    populateAndAdd(oGoodsIssue);
private void populateAndAdd(Documents doc)
    doc.Comments = oDocument.CardCode + " " + oDocument.DocEntry;
    for (int i = 0; i < oDocument.Lines.Count; i++)
        oDocument.Lines.SetCurrentLine(i);
        addLineToDocument(doc, oDocument.Lines);
    int RetVal = doc.Add();
    //Check the result
    if (RetVal != 0)
         String message = "";
         if (isDelivery)
             message = "Unable to add the goods receipt\n";
         else
             message = "Unable to add the goods issue\n";  
             message += B1Connections.diCompany.GetLastErrorDescription();
         B1Connections.theAppl.MessageBox(message, 1, "", "", "");
private void addLineToDocument(Documents doc, Document_Lines sourceLine) {
            doc.Lines.ItemCode = sourceLine.ItemCode.Trim();
            doc.Lines.ItemDescription = sourceLine.ItemDescription;
            doc.Lines.Quantity = sourceLine.Quantity;
            doc.Lines.Price = 0.0;
            doc.Lines.WarehouseCode = "M003";
            SAPbobsCOM.Items item = (SAPbobsCOM.Items)B1Connections.diCompany.GetBusinessObject(BoObjectTypes.oItems);
            item.GetByKey(sourceLine.ItemCode);
            if (item.ManageBatchNumbers.Equals(BoYesNoEnum.tYES))
                for (int i = 0; i < sourceLine.BatchNumbers.Count; i++)
                    sourceLine.BatchNumbers.SetCurrentLine(i);
                    doc.Lines.BatchNumbers.Quantity = sourceLine.BatchNumbers.Quantity;
                    doc.Lines.BatchNumbers.BatchNumber = sourceLine.BatchNumbers.BatchNumber;
                    doc.Lines.BatchNumbers.Add();
            else
                if (item.ManageSerialNumbers.Equals(BoYesNoEnum.tYES))
                    for (int i = 0; i < sourceLine.SerialNumbers.Count; i++)
                        sourceLine.SerialNumbers.SetCurrentLine(i);
                        doc.Lines.SerialNumbers.InternalSerialNumber = sourceLine.SerialNumbers.InternalSerialNumber;
                        doc.Lines.SerialNumbers.ManufacturerSerialNumber = sourceLine.SerialNumbers.ManufacturerSerialNumber;
                        doc.Lines.SerialNumbers.Add();
            doc.Lines.Add();
ODocument in this case is the oReturns
hope it is understandable...
