There are many tools available in Anaplan that can help you view and analyze your data, in a module or classic dashboard.
More complex tasks can also be performed. You can apply conditional formatting to highlight important information in your module, or use Drill to Transaction and Drill down to understand the formulas behind your data.
Before you make any changes to your module or classic dashboard, always refresh your data to make sure the data you use matches the data held on the server. Any changes that you do make are easily reversed.
