Hi Jana,
From logs, please find the what time your chain was running.
based on time, you can find finished jobs at SM37.
Later from those jobs you can find which job is related to your chain thru start varaint-->abap program of STEP option on menu bar.
once you find your chain related job, you can keep their status as Schedule(Hold) from release.
Based on your log, You can find tomorrow jobs(bi_process_trigger) which are in released state from SM37.
Check each job, STEP option-->ABAP Program-->Start variant(menu option), there you will find your chain name.
Thanks
