Report : To display VBRP details based on BSID Records

Dear All,

I have to display the Item details from VBRP based on the BSID Table. So Now I am selecting the VBRP details based on the VBELN in BSID. But For some BSID records there is no vbeln value. Then

1 ) How can I display the item details of that records.

2 ) Where it is stored.

3 ) Is it something related to type 'RV' ?

Please help me...

Thanks in Advance..

Regards,

Lijo
