WS_DELIVERY_UPDATE_2 Automatic Creation of Serial Numbers?

Hi,

I was using BAPI_GOODSMVT_CREATE to make GR for inbound delivery but now I changed it to WS_DELIVERY_UPDATE_2.

With the first BAPI, there was a parameter to create serial numbers automatically, for the second one I couldn't find any.

Is it possible to create serial numbers automatically with WS_DELIVERY_UPDATE_2?

Thanks.
