Go to Income tracker>>Track units>>Click on delete option against the unit which you want to delete>>Save changes.
Note:
1.If a flat was wrongly created by mistake, and a receipt got posted against that flat, it can never be deleted ( otherwise there will be a missing receipt in the sequence ). In these cases, you
have to
deactivate the flat.
2.If any user is assigned to the unit it can't be deleted, so make sure there are no users assigned to the unit before you delete the same.
3.Make sure there are no active financial data against the unit(if there are any, the unit can't be deleted).
