SAP B1: Issue with create a delivery with Assembly BOM item link to a Sales Order

Hi Experts!

I got an error: "Cannot add row without complete selection of batch/serial numbers"

when I try to create a delivery with BOM assembly item and Batch numbers by DI API.

Could you please give me some advises?

item2 is managed by butch numbers.

Here's my code:

oDelivery = (Documents) Program.dossier.GetBusinessObject(BoObjectTypes.oDeliveryNotes);
oDelivery .CardCode = "C0000";
oDelivery .DocDueDate = DateTime.Now;

oDelivery .Lines.BaseType = 17;
oDelivery .Lines.BaseEntry = 444;
oDelivery .Lines.BaseLine = 0;
oDelivery .Lines.Quantity = 10;
oDelivery .Lines.BatchNumbers.BatchNumber = "TEST01";
oDelivery .Lines.BatchNumbers.Quantity = 20;
int result = oDelivery .Add();

if (result != 0)
     Program.SBO_Application.MessageBox("Error : " + result.ToString() + "--" + Program.dossier.GetLastErrorDescription()); 

Thank you very much in advance.
