Hi Puneeth,

I believe that export is only allowed from buffers visiting files, when
I tried to reproduce your problem exporting from a buffer without a file
name I get the following error message

  (error "Need a file name to be able to export")

which is thrown by org-latex, org-docbook, or org-html on attempted
export.

Unless I'm missing something, it is not a problem that Babel expects
org-current-export-file to have a value.

Best -- Eric
