Did you confirm a service charge statement by mistake, or do you want to redo it to send it to all tenants at once? There is no direct cancellation: you need to delete the statement (and the associated sales invoices), then recreate it. This applies to buildings only.
Steps
In the Properties menu, on the left, open the relevant building.
Open the Tasks tab and scroll down to the History section.
Find the service charge statement, click the three dots … to the right of the row, then Delete.
Then open the Sales invoices tab and delete the associated sales invoices for this statement. (Purchase invoices are not affected.)
You can then recreate the statement and send it to all tenants at once. Need help recreating it? See How do I create a service charge statement?
