The ***Comparison*** section at the top of the dialog box is where you define the type of Forecast(s) you want to use (Baseline, Forecast, Statistical) and the number of periods prior you want to compare to. By default, the report shows the current forecast versus the same period last year for all periods in the forecast horizon. Unchecking the “*Current forecast vs. same period last year*” checkbox allows you to customize the comparison periods.

The ***Forecast periods to consider*** section allows you to set the number of forecast periods to monitor and to specify if you want to look at each individual period or at the cumulative total across the specified forecast periods. The default setting (“*Cumulative*” is not checked) monitors all forecast periods individually.

The ***Include ***section allows you to specify which statistics you want to show in the report. By default, the report shows Deviation and % Deviation.

The ***Display***section lists the optional columns you may include in the report.

- ***Status***: Displays the status.
- ***Status*** ***Assigned By***: Displays the user who assigned the status.
- ***Status Assigned Date***: Displays the date the status was assigned.
- ***Last Viewed By***: Displays the user who last viewed the item.
- ***Last Viewed Date***: Displays the date the item was last viewed.
- ***Description***: Displays the Description for the item in the historic data file.
- ***Pareto***: Includes four additional columns: Pareto, % of Total, Ranking and Cumulative %. Consult [The Pareto Tab](https://dev.forecastpro.com/documentation/forecast-pro-trac/forecast-pro-options/the-pareto-tab/) for more information.
- ***Comments (Y/N)***: Displays a value of Yes or No to identify which items have item-level comments associated with them.
- ***Comments***: Displays the most recent comment.
- ***Custom Filters***: If you have included filters in the project (see [Custom Filter Fields](https://dev.forecastpro.com/documentation/forecast-pro-trac/optional-data/custom-filter-fields/) in *Setting Up Your Optional Data*), you may add those to the report.
