How to adjust charges on a closed invoice on Apex?

In order to reverse the revenue that was charged on a normal Front Office invoice and the invoice is now in archive, the below steps need to be followed:

Steps:
  1. To fix the mistake a House Account needs to be created in order to reverse the charges posted. To create a new House Account navigate to Processing -> Reception -> Room Rack, or alternatively click on Room Rack on the speedbar.
  2. Next select the  "Open House Account" button and complete the guest or company details used in the previous reservation as normal and click on the "Save" button. 
  3. Once the House Account is active the revenue adjustment needs to take place, the user needs to confirm the amount that needs to be reversed, as well as the corresponding charge code, for example: Accommodation 2500.
  4. Select the "Invoice" tab and click on the "Adjust" button. A confirmation window will appear prompting the user to confirm the adjustment.
  5. Next enter your Supervisor Authorisation code, as well as the reason for the adjustment.
  6. Select the charge code that needs to be adjusted for example: Accommodation.
  7. Enter the reference and the amount that needs to be adjusted and click on the "Post" button.
  8. The amount will now have been reversed and the invoice will now reflect a credit or negative amount.
  9. Next click on the "Pay" button and select the relevant payment code which will be used to refund the guest and enter a reference.
  10. The amount that needs to be entered needs to match the charge amount, normally a payment will already be a negative but in this instance, a negative (-) has to be placed before the amount to render the invoice settled, for example -2500. 
  11. The House Account invoice can now be printed as proof of the reversal and closed.
