How to find Process Chain Name from SM37 JOB.

Hi Gurus,

my actual requirement is finding the process chains for the Priority 'A' job's..

i have some 1500 jobs which are running with priority A, i need to identify the process chain for that , i am looking for only DTP jobs,

there is a way to find out it with the job log , where we get log id for the particular job and we can get process chain name form the log id from table RSPCLOGCHAIN,

i can not go to every job and take the log id  because i have to do this for 1500 jobs..

can any one help me with the tables where it get capture, like job id or job log or PID with process chain name..

i have checked the table TBTCO it doesn't help me,

Thank you,

Vijay.
