How to create single Inbound Delivey for multiple PO line items through Tcode VL31N?

Dear All,

Could you please suggest me how to create single inbound delivery for multiple PO line items through Tcode VL31N.

I have already done BDC recording program to create inbound delivery with Handling Units with reference to Single Purchase Order.. and its working fine. Now i needs to add this scenario also.

Could you please let me know is there any BAPI or ALE IDOC to handle all these scenarios..

Thanks in Advance.

Regards,

Prabhakar
