# Runtime Variables

> For the full documentation index, see: https://docs.mulesoft.com/llms.txt

The Runtime Variables action step provides a set of variables that the workflow populates at
runtime. Use these variables to get information from the runtime context.

The following variables are available:

- **Project Name**

  Name of the _Workflow_ project

- **Project GUID**

  GUID of the _Workflow_ project

- **Run GUID**

  GUID related to the execution of the _Workflow_ (regenerated for each run)

- **Time**

  Actual time as local time or UTC in configurable format

- **Date**

  Actual date as local time or UTC in configurable format

- **HostName**

  Name of _Host_ system

- **UserName**

  Name of the user

- **RandomVariable**

  Positive random number with a configurable range of values. The workflow generates a different
  number on each run.

- **Business Process ID**

  ID of the business process

- **Session Id**

  Terminal session ID of the environment where the bot is running

- **Session Name**

  Terminal session name of the environment where the bot is running

- **Bot ID**

  GUID of the bot that is executing the workflow

_RandomVariable_ is an integer value. All other variables are strings.

Debugging the _Runtime Variables_ action step is not possible. Therefore, the debug functionality is
disabled and you cannot set breakpoints for this action step.

## Properties

- **Write Runtime Variables to Logfile**

  When enabled, the workflow writes runtime variables to the Stc log file.

## Outbound Variables

- **Runtime Variables.\[name of the runtime variables\]**

  Content of _Runtime variables_.

## Wizard

Use the wizard to add new runtime variables and specify their **Name** and **Description**.

To make variables available in later transactions, select **Make Variables available in all further
Transactions**.

Use the **Delete** button to remove variables.

The values listed in **Sample Data** are for local testing. If a bot completes the workflow, the
workflow re-determines the values at each run.

Some variables such as **Random Variable** show a **Settings** menu that you can expand for further
configuring the variable.
