Attendance changes were made in the previous year database, and recomputing YTD Information on the Monthly Attendance Summary is not capturing the changes.
Cause
Typically this issue arises after the New Year Rollover as users do not have Security permissions (Insert, Update, Delete), to the Year-to-Date Attendance Info (YTD) table in the Last Year tab.
Resolution
Update Group or User Permissions in the Last Year tab
Step 1: In the new school year, navigate to Users or Groups > Click on Last Year (20##-20##) Tab
Step 2: Search for Year-to-Date-Attendance Info (YTD) > Check Insert, Update, Delete
