contents in attachment of Supplier registration form is missing

Dear Experts,

I am using function module 'ROS_BUPA_PUT_ATTACHMENT' for creating attachment to Supplier registration form. My problem is i am able to see the attachment in Supplier preselection - Supplier dispaly form. When i click the attachments there is no contents. Kindly guide me if im missing any parameter, or any other function module has to be used to set the content to the supplier form.

Thanks & Regards
