Used to configure the execution of a Business Rule (DMN). Process execution makes the call and completes in synchronous nature.

Supports Business Rules in DMN 1.3 stored in Orchestrator.

**Implementation >** Type: Execute Business Rule.

## Available actions for Business rule tasks

The **Action** dropdown in a Business rule task allows you to define the type of external execution the process should call. Each option maps to a specific UiPath capability or integration method. Below is a brief overview of each option:

* **None**

   No implementation is configured for the Business rule task.
* **Create action app task**

   Creates a task in an Action App for user interaction, without waiting for task completion.
* **Start and wait for RPA workflow**

   Starts a deployed RPA workflow (e.g., UiPath Studio project) and waits for it to complete before continuing.
* **Start and wait for agent**

   Starts a UiPath agent (a reusable logic block) and waits for it to finish execution.
* **Start and wait for external agent**

   Triggers an agent hosted outside UiPath, such as CrewAI, Salesforce, or ServiceNow, and waits for the result.
* **Start and wait for API workflow**

   Executes an API-based workflow and waits for a response.
* **Start agentic process**

   Starts a process based on agentic design (modular logic), without waiting for it to finish.
* **Start and wait for agentic process**

   Starts an agentic process and pauses until it completes execution.
* **Execute business rule [Preview]**

   Evaluates a business rule and uses the outcome in the process (currently in preview).
* **Create queue item**

   Adds a new item to a UiPath Queue for asynchronous processing, without waiting for result.
* **Create and wait for queue item**

   Adds an item to a Queue and waits until it is processed before moving forward.
* **Execute connector activity**

   Runs a preconfigured Integration Service connector activity (e.g., Salesforce or Slack).
* **Wait for connector event**

   Pauses the process until a specific event is received from a connector (e.g., form submission or external trigger).
* **Execute script**

   Runs a short script (JavaScript or similar) during the process for lightweight logic or transformation.

To add an additional output, select **Add new** to introduce a new variable directly within the Business rule task. The newly introduced output will be available in subsequent steps.

The **Add variable** dialog lets you define a new variable by specifying its name, type (such as String, Number, Boolean, etc.), and optional default value. Once saved, the variable becomes available for use in inputs, outputs, or expressions within the Business rule task.
