Hi Venkat,
In SM37 with DTP_* --> select Active jobs --> execute it will display all the active jobs which are assigned for DTP process.
DTP is by default executed in background -- you can find more than 1 job for a single DTP load.
If the jobs are finished then you might select the Finished along with Active in SM37 so that it will display all the finished and Active jobs.
You can also monitor the PIDs in Sm66( job overview) -- here it will display from which table the data is being read and processing status.You want more details you can goto local work processes and can check the SQL script or table where load is at that point.
Regards
KP
