[Koha] monitor load marc records

Hello all I would like to know if we can get the ID of the records loaded (import marc record tool). I mean... Imagine you are loading a catalogue...all good, so you load the second...all good too, but with other load we have an error, so we must remove from koha this catalog. I supose this remove is done with the range of ID of the records loded no? Can some one tell me the procedure? And then, whitch mysql tables are filled when records are loaded? Thanks a lot in advance
