You must have an OLDSAC column in the People list in order to generate Previous Results comparatives. OLDSAC = the Subject Access Code (SAC) that was assigned to the individual in the previous 360.
If your People List lacks the OLDSAC column, go to the PEOPLE tab -> Export DataBank sub-tab. Export your People List, then open the resulting file in a spreadsheet. Add the OLDSAC column and populate it with the SACs from the previous assessment, but only for the Subjects. Then go to Import DataBank sub-tab to re-import the updated People List.
Note: The SAC (Subject Access Code) is the first part of a Subject’s PID, formatted as follows: abc-123456.
