Deliver line item Creation

I created Delivery using the function module shp_vl10_delivery_create by passing sales order info.But how to create line item when there are different materials .This function module works (creates delivery) when there is one line item for SO and if we pass full ordered quantity only.is there any other fm for creation of delivery ?

i want one more function module to create delivery line item also.please help me in this way, as i urgently need this functionality to incorporate dynamic delivery creation.
