Hi!
You might want to first go to Data Administration” app → “Maintenance” and perform the maintenance tasks:
- Clear analytics tables
- Reload Apps
- Clear application cache
- Update org unit paths
- Delete all soft deleted values/events and enrolments.
Also check data integrity.
Then rerun Analytics Tables export
It might be necessary to do it several times if it fails.
If this does not help, feel free to get back to me.
Good luck,
Yury
