Database backup through expdp into different user

Dear All,

Recently we start using expdp utility to taking our backups, and we notice that we can only import in the same database user, can someone explain how we can import data into different user.

I am using following command to get exported data:

expdp scott/tiger@abdb directory=dpdir dumpfile=abdb.dmp logfile=abdb.log

for say we want to import abdb.dmp from scott to comptest.

Regards,
