This error occurs because there are students who were enrolled in the district but do not have any records in the Student Course Section Completion (SCSC) extract.
This is only a warning. If a student was previously reported for the school year and is no longer enrolled at the end of the school year, there may not be any records in the SCSC file. However, confirm that all the students with this warning have been inactivated during the school year. If a student was enrolled at the end of school year, determine why their course enrollment (CAR) was not submitted.
