Background jobs and variant

Hi Guys,

I have couple of question regarding background jobs. Can anyone please tell me how to create user variant for background jobs for example I want to create a user variant for this background jobu201D PFCG_TIME_DEPENDENCYu201D I can go to se38 and create variant for example (Ztest) but what is the benefit of this variant?

My second question is; please let me know what other standard background jobs should be set up in production other then PFCG_TIME_DEPENDENCY. Is basis user who will create batch jobs have admin access?

Thanks in advance
