# Anomaly Main Screen

> [!NOTE]
> This section of the Handbook explains how to use and interpret the Anomaly Main Screen.

The Anomaly Main Screen shows a Grid of all registered Anomalies across PEI, Civil, and PLSS. To open it:

- Click **Anomalies** in the IMS Main Menu.

By Default, The Anomalies Main Grid opens grouped by **Active = True** by default; clicking **Clear all filters** restores this default.

The Anomalies Main Screen follows the same basic structure as the other Main Screens in IMS. To learn more about the features in common with other Main Screens, see: [IMS Main Screen (Grid List)](/v410/docs/basic-navigation-other-main-menu-options).

## Filtering and Grouping Anomalies

From the Anomalies Main Page, several filters can be used to drill down the search results for the shown list of Equipment. Some examples of filters include:

- **Date-range filters:** Identified Date Range, Revision Date Range, Closed on Range.
- **Group-by filters:** Active, Anomaly Status, Anomaly Type, Anomaly Response, Schedule Missing (Yes/No), Action Missing (Yes/No), Visible In, Owner, Tag Labels, Equipment Group/Class, Planned Schedule.
- Use **Schedule Missing** or **Action Missing** (or both) to find Anomalies awaiting a follow-up action.

To filter a list:

1. Click on the *filter* button.
2. Check the filters that you want to use.
3. Click **Show …**.
