# Applying global filters

Global filters apply consistent filtering across all tabs within a Vizpad. Any filter configured at the global level cascades to every chart and tab in the Vizpad, ensuring uniform data context across the entire dashboard.

1. In a Vizpad, click on the **Add Filter** button and the following menu will be displayed.

2. If you want to apply a global filter, then enable the **Global Filter** toggle. All subsequent filter configurations apply to every Vizpad tab.
3. If you want to apply filters to any date columns, then enable the Date filter toggle.

When **Date filter** toggle is disabled, only measures and dimensions will be displayed in the **Select Column** dropdown. If it is enabled, then only date columns will be displayed in the **Select Column** dropdown.
{% endhint %}

4. Once **Global Filter** toggle is enabled, then the minimum and maximum range will be auto-selected. However, it overrides manual range modification so you can make necessary changes as required.
5. The auto-range will be selected as follows:
   1. **Measures**: Selects the minimum and maximum values of the measure.
   2. **Dimensions**: Defaults to `IN` (inclusion) operator.
   3. **Date columns:** Calculates `MIN(date_column)` to `MAX(date_column)` from entire dataset.

6. Enable the **Use Alignment Mapping** toggle if you want to refer only the mapped measures. This will be displayed only if **Date filter** is enabled.
7. Click on the **Select time period** field and the following window will be displayed. The available **Measure → Date** mappings for the Business View will be listed.
8. Choose the required time range from the available list.

9. Click on **Apply** to save the changes. The date filter will be applied to the selected chart(s).

{% hint style="success" %}
Because you mapped **Sales, Quantity, Discount → Order\_Date** and chose **Last year** with **Date mapping** enabled, Tellius first kept only the rows whose **Order\_Date** fell in last year. Then it aggregated by **Category**.

\
Without mapping, the time filter could have hit a different date column or been applied across measures. Mapping forces the filter to use the correct date per metric, so your bars and lines are apples-to-apples for “last year.”
