Problem in BADI calling a FM

Hi all,

I have a BADI which calls a FM. This FM picks up the file from hard drive D and sends a mail with that file as an attachment. Stand alone FM is working fine. But when i call it through BADI, mail is sent but not the attachment. I am using BCS classes for sending this mail..

Why FM is not seding the attachment when called through BADI?

Please help.

Thanks.
