'external table error ora-29913 on just one table

I'm getting an ora-29913 external table error. Error opening file /usr/app/xyz/abc.txt. The uniqueness behind this we have 15 other external tables all referring to same directory path. But the problem is only occurring with just one external table. I checked the table all_tab_privs for privileges for the table which is getting error and a good external table, and I don't see any permission issue there. Earlier the file was ftp'ed. Now its sent via Sftp. Could that be the issue? Please assist.
