# Expose Step as a Rule

## Overview

There are many steps in Decisions that are evaluated as **Rules** when used as a step in a**Flow**. There is a setting available for Rule steps that will expose a step as a Rule with a True or False outcome; when enabled, this setting will show a True path and a False path for these rules. When this setting is disabled, the step will have a single path as an outcome “done,” and the True or False result will be returned as output data. By default, this setting is enabled for all built-in Rules.

## Example

The following example will show the differences when this setting is both enabled and disabled. This example uses the True False Rule step and demonstrates how the resulting outputs and the outcome paths differ when **Expose Step as a Rule** is enabled or disabled.

This example requires knowledge of how to Create a Flow, along with an understanding of how to add steps in the Flow Designer. For more information, please visit the following articles:

- [Creating a Flow](https://documentation.decisions.com/v9/docs/create-flows)
- [About Flow](https://documentation.decisions.com/v9/docs/flows)

1. In the Flow Designer,  add a **True False Rule** step from the **Toolbox > RULES** category. This is a **Rule** step that has two outcome paths: **True** and **False**.
2. In the **Properties**panel, under INPUTS**> Value,** change the boolean mapping to **Constant**and change its **Value**from False to **True**![](https://cdn.document360.io/6ef8bcc1-6489-4486-9ad1-83acff7e5df0/Images/Documentation/2025-06-17_12h11_15.png)
3. Under OUTCOMES, notice the **Expose Step as a Rule** boolean is enabled.
4. Connect **True**and **False**lines to **End**Step.
5. Select **Debug** in the Top Action Panel.![](https://cdn.document360.io/6ef8bcc1-6489-4486-9ad1-83acff7e5df0/Images/Documentation/2025-06-17_12h11_54.png)
6. Click START DEBUGGING.
7. In the resulting **Debugger**, right-click on the **True False Rule** step and select **Execution 1 > View Input/Output Data**. Notice in the OUTPUTS that the Rule step followed the **True** path, and the data brackets are empty.![](https://cdn.document360.io/6ef8bcc1-6489-4486-9ad1-83acff7e5df0/Images/Documentation/2025-06-17_12h14_07.png)
8. Select OK and close****the **Debugger**.

### Disabling Expose Step as a Rule

1. In the Flow Designer with the same **True False Rule** step selected, disconnect the **True**and **False**paths from the **End**step.
2. Next, under **Properties** > OUTCOMES, uncheck the boolean **Expose Step as a Rule**. Notice that the **True False****Rule**step has a single **Done** path. ![](https://cdn.document360.io/6ef8bcc1-6489-4486-9ad1-83acff7e5df0/Images/Documentation/2025-06-17_12h37_02.png)
3. Connect the **Done**path to the **End**step.
4. Save and select Debug from the Top Action Panel.
5. Click START DEBUGGING.
6. In the resulting Debugger, right-click the **True False Rule** step and select **View Input/Output Details**. The OUTPUTS show the step followed the **Done** path, and the data brackets contain the output of the Rule.
