Background jobs

Hi

I have a transaction code which takes up very high CPU time. It is found that the program associated with this Tcode has coding issues. I would like to find out if there are any background jobs which would use this program. If I have this information, I will know the jobs which will be fine tuned as a result of adjusting the code for this program

Is there a way to find out this?

I would also like to find out background jobs that are run by Company code. Is there a way to find out this?

thanks
