Lsmw for sales order upload

Dear Friends,

I am trying to upload sales order data using transaction VA01 by Batch Input Recording method in LSMW. But I am not able to get line items due to the fact that I am not able to assign two source structures. So i am trying to upload by Abap Coding in LSMW. But still I am not able to get the Item Data. So Kindly help me in this.

With Regards,
