Adding a new feature to reverse the booking status from resident to booking confirmed or booking completed.

• On the booking details page, add a new option called 'Reverse Booking Status' into the button 'More'

• After clicking the option 'Reverse Booking Status', there is a modal coming up above
  • Title: Reverse Booking Status
  • Description: Please review the booking status this booking would be 
  • Details: Display the current booking status and the future booking status eg. Resident → Booking Confirmed or Booking Completed
    • Text: The booking status will only reverse to booking completed if all before check-in tasks have been completed previously

• When the button “Submit” is clicked, there is a double-confirmation modal coming up
  • Text: Booking status will be changed immediately. Are you sure to reverse the booking status?
    • Click “Yes, reverse”, the modals will be disappeared and the booking status will be changed
    • Click “Cancel”, the double-confirmation modal will be disappeared
    • Click the button “X”, the modals will be disappeared and the booking status will not be changed

The logic of reverse booking status from resident to booking confirmed or booking completed

• The reverse entry will only be available when the booking status is resident
• There are no pending or confirmed after-check-in amendments for the booking
• The booking status will roll back to what it was before (one step back)
  • If the booking completed has been populated, reverse the booking status from resident to booking completed
  • If the booking confirmed has been populated, reverse the booking status from resident to booking confirmed
• Change the bed status from occupied to booked
  
• The alerts need to be re-calculated upon successful reversal.
