No steps in database found for job &

What causes this issue?

The BP_JOB_READ function module was unable to find any job steps for the
job named in the message. Job steps are defined in table TBTCSTEP.
This error suggests that a problem has occurred in the database system.
The background processing system does not allow a job to be saved
unless at least one job step is defined for it. Therefore, this error
should not occur if the database system is operating normally.

System Response

The job data has not been read. The function that you were performing
has been terminated abnormally.
