In case you missed, it CCS have advised that the end of financial year reconciliation period for 20-21 will end on 8th August this year. Make sure all your attendances for the financial year just gone are finalised (that includes submissions and variations if needed) before that date. Access the Att Summary from the main service menu in Smart Central. Other software providers may have something similar (if you're lucky 😜).
Making any changes to last year's attendances after that date is guaranteed to be a headache if not outright impossible. Here's the full announcement from the Department of Education, Skills and Employment : https://mailchi.mp/a9b5bcd2a738/session-reports-deadline-8-august-ccs-rate-changes-from-12-july
