# Set Otherwise Action

## Overview

The **Set Otherwise** action for a **Truth Table** sets a default execution for a column if there are no matching results. This allows a Truth Table to provide specialized outputs for cases where some column values can have a default match if no other matches exist. Otherwise can be used in two scenarios: at the bottom of the first column or when there are Merged Rows in the column to the left.

## Example

1. [Create a Truth Table](/v9/docs/creating-a-truth-table).
2. Configure the Truth Table, then expand the action menu for the last cell under the first column. Choose **Set Otherwise**. ![](https://cdn.document360.io/6ef8bcc1-6489-4486-9ad1-83acff7e5df0/Images/Documentation/2024-08-07_09h40_55.png)
3. If the first column contains merged rows, the next column can be set to **otherwise**. With at least two rows merged in the first column, navigate to the second column, the last row of the merged rows can be set to **Otherwise**.

4. Debug the result; in this example, the Vehicle was an SUV, and the driver's age was 81 resulting in the Truth Table passing down the **Otherwise**path.![](https://cdn.document360.io/6ef8bcc1-6489-4486-9ad1-83acff7e5df0/Images/Documentation/2024-08-07_09h43_40.png)
