SLM:Add attachments by Buyer during Invite supplier for Registration process

 Hi

We have a business requirement to send Drawings,Manuals to Supplier during the registration process.

During the supplier registration  process,the buyer (supplier administrator) clicks on Register Supplier and provides Supplier Address contact details,then in attachments section adds the  Drawings and clicks REGISTER button.

A notification goes to supplier contact and when notification is opened,they could not find the attachments send by the supplier administrator.

Is it a bug or ER ?

If Attachments are not transmitted during registration process,how do we communicate the suppliers  in the system for providing Drawings?
