You get the warning when generating a new BT tax return

Load BT and the client and correct period
Edit and Losses
Review and correct all the entries for the relevant column period
If all correct – under the relevant CTAP column click EDIT
Review and correct all the entries
If all correct – Click on the top left box ‘Brought forward’ then use your TAB key and tap it multiple times – this refreshes the boxes and may auto edit a incorrect value. Once its gone full circle then click UPDATE TOTALS and then Ok
Now regenerate a new tax return and the warning should not show
