Navigate to the KPI View. After you have made your relevant settings of accounts, value lists and views, select the desired plan-act comparison (e.g. Act/FC vs. Plan or Act/FC vs. Plan 2) in the second drop-down menu (value lists). impact automatically calculates the deviations between the selected value lists. Via the function button Reports you can download the selected views as Excel file for further analyses (not re-importable).
