create multiple sales orders based on single sales order

Hi Experts,

I have a requirement to create multiple sales orders based on single sales order.

i.e. When sales order is created manually, before saving the original sales order , we has to split single sales order into multiple sales orders.

EX: From VA01 an sales order is created manually. Before saving this sales order, we has to split the single sales order into multiple sales order.

1. Using BAPI_SALESORDER_CREATEFROMDAT2 what data has to be passed, can i pass any reference data to bapi to create multiple sales orders.

2. How to write the logic in output type, any configuration has to be done. Explain the steps needs to be done.

How to achieve the above requirements.

Regards,

Vinu Karthik.
