Need list of background jobs with their step owners

Hi,

We need to replace individual's IDs defined as step owners in background jobs. From SM37; we can find the list on basis of 'job created by' but we cannot find the step owners of jobs which are different in mancy cases. Could you please advise how can we find list of all background jobs defined in the system along with their step owner.We checked table TBTCPV it does not seem to be precise

Thanks,
Varun
