Sage One FPS Adjustment


I've processed my payroll using Sage One for August and submitted the FPS.

I've had to go back and make a change to one employee so I edited the Pay Run.  There doesn't seem to be a way of submitting a FPS adjustment.  The advice I've read on the help page just says carry on as normal and when I submit the FPS the following month the totals will agree.  IS this correct?

Also, which figure do I base my HMRC payment on?  The P32 report is still showing the totals from before I made the amendment.
