Session Error – Session record already exists for the same period
Your Internet connection may have crashed previously while upload attendances – Synchronize with CCMS.
If nothing shows up with a CCMS synchronise check that the hours haven’t been double entered under Data Entry, eg. 2 Tuesdays sessions. CHECK THE HOURS AND THE SESSION DESCRIPTION. Could be that the description says BSC but the hours are ASC or that the child has moved rooms and has been booked into both (auto generated then the template is changed and re-generated).
Correct the error and re-upload attendances.
