I'm not sure, I understood. Anyway, I spoke with my manager and he explained what he was talking not about reports (which would be really hard to change), but about some program, which I use to generate a file, which then processed by our Production department. So, my task becomes much easier (I hope). I haven't checked it yet, though.
