any fm to get belnr?

hello alll

is there any functional module which gives me the BELNR(of bseg) by passing the vbeln.

yeah ...we can do tht by passing bseg table ,,,,but its taking loads of time to give me the output as its not a primary key or secondary key.....

when i m using this condition in the prog i cannot use inner join as its a cluster table . if i m writing a condition it is effecting my prog performance

regards
