Sometimes we have had to cancel multiple weeks of attendances to make a change (eg. JET, change of guardian, etc) and then reupload (see uploading multiple weeks of attendance).
Go to Query Atten and enter the first week number to be cancelled.
Tick the Use Range box and enter the last week to be cancelled.
Click on Display.
Find the child you want to cancel and click to high and click on Filter By Selected Child to just show this child’s attendances.
Click on the first instance of attendance and, if cancelling all weeks, hold down the Shift key and click on the last instance of attendance.
If only cancelling some week hold the Control key down and click on the weeks you wish to cancel.
Click Cancel Attendance
