A. In the second year if you wish to retain the rolled over 'prior year' figures you must delete the 'prior year' column from your second year import. If you have a prior year column and leave it blank it will over-write the rolled over figures to zeros (see prior question here: http://support.auditassistant.com/entries/84836-q-how-should-i-import-data-in-the-second-year-what-about-the-prior-year-data)

If you have imported and something has gone wrong and you use the 'clear' button all your data will be removed - so this should be a last resort. If you have imported details that don't match the prior year or have deleted the prior year figures we suggest you create a correct trial balance import that corresponds to prior year names and account codes but includes a complete prior year column and import that over top of the existing details rather than deleting existing details. This will retain your mapping and sub-totals from previous years - just go through and delete any extra incorrect data.
