I had incident created under "Log Entries" for a student but the wrong school was entered. How do change the school to correct school where the incident took place? I tried search for it in DDA but I could find it in the Logs. Are incidents on a different table?
Incidents and Log Entries are completely different things. Incident Management exists across a bunch of different tables. A LOT of different tables, and they aren't available in DDA.
You should be able to change the school within the incident.
Just make sure you are in District Office when you try to change the school.
