2777345 - Transport Request can be imported into a non-existing client

You import a transport request from OS level, using a client that does not actually exist in the import system.
Generally, imports should be terminated due to this non-existing client, but as a result, the client independent objects are actually imported and the client dependent objects are not.  

From import log, you can see transport is continuing.
