After you have generated a Simulation you may still modify some elements. In case you forgot a metric or missed a KPI, Levers allows you to add or remove them at will. Since dimensions are used to organize the data, you may NOT edit them after a Forecast has been generated, but you do have the ability to add filters to narrow your view.
Adding and Removing Metrics and KPIs
Underneath your KPI banner there are two tabs for "Metrics" and "KPIs." Selecting each tab will enable a drop down where you can select or remove metrics or KPI. After you have made additions or removal, select the "Update" button to execute the changes.
Wait a moment for you Forecast to update and you will see the changes reflected within the table and Executive Summary.
Filtering Dimensions
Underneath the KPI banner in a Forecast, select the "Search" tab to bring up the Dimension Filter Selector. You may add more than one dimension filter by selecting the "+" button. Click "Update" to execute changes and see the filters reflected in the table.
Dimension filters will also modify KPI totals to reflect the subset of data in the table.
