CERT048
A teacher was reported who was employed on Census day but has no Non-classroom based job assignments or assigned Course Section records.
In other words, you are trying to report a teacher (because you've already uploaded a staff demographic and staff assignment file), but you are getting a cert error because that teacher doesn't have any course records associated with her/him (likely), or they are a teacher on special assignment or something and don't have a non-teaching assignment.
So the system is asking you "Did you forget to upload this teacher's course records?"
