Need to add new batch split to the existing inbound delivery item - VL32N

Hi ABAPers,

I need to add new batch split to the existing inbound delivery item.

I have inbound delivery with item 000010 with batch splits 90001,90002,90003.

Now i need to add batch split 90004 to same inbound delivery item 000010.

Please suggest me any FM/BAPI and fields which we need to populate.

Regards,

Sekhar.
