Hi,
All this information is in DS_PENDING_JOB table in the BO repository.
The description of this table can be found here:
The description is for BO repository 5.x but this table did not change in BO 6.x so it is (or should be) valid for your table as well.
And have also look at these 2 universes in the BOB’s Downloads section:
BCA Auditing and Reporting
6.5.1 Repository universe for User/Group/Document & BCA
