Regarding Attachment in Change Request Header

Hi Experts,

Can anyone tell me where the "attachment file" of CR header(that we upload) go and get saved. I am looking for the actual place(may be some content repository) where these attachment files are saved physically.. I am not looking for any tables like USMD1211 and USMD1212...?

Kindly help me know it for BP, MM and FI objects.. all 3 objects

Would highly appreciate your reply.

Thanks, T
