If you're pre-enrolling a student for 9th grade Next year, the Initial Ninth Grade Entry year (STU.INE) defaults to 2018-2019 and there is no way to change it to 2019-2020. The Cohort (STU.CHT) will automatically calculate to 2021-2022 and cannot be changed on the Demographics page. After the Rollover the INE would need to be updated to 2019-2020 and the CHT will re-calculate to 2022-2023.
If you have already done your Rollover, you can still use a CHANGE query but would have to modify the IF statement
Programming is aware of this and is working on a fix. This should only affect pre-enrolled 9th graders as any other pre-enrolled grade level will have an INE prior to this year and can be set during pre-enrollment.
