The **Work Module** executes the code contained within its scope (it's recommended to use an **Invoke WorkflowFile** activity). Log messages are generated for each execution attempt, exceptions are automatically caught and, in case of exceptions other than BusinessRuleException, the code can be automatically re-executed up to a configurable number of times.

The package defines a custom enum type called **ExecutionResults** used to output the outcome of executing the module's code. Possible output Result:

*   **ExecutionResults.Success** \- if the code executes successfully.
*   **ExecutionResults.BusinessRuleException** \- in case a BusinessRuleException is caught. If ContinueOnError = False, the exception is re-thrown
*   **ExecutionResults.SystemError**  - in case a non-BusinessRuleException is caught and the number of retries is exceeded. If ContinueOnError = False, the last caught exception is re-thrown

**In Arguments:**

**\- Automatic Logging Options:**

*   **LogExecutionStart** (LogExecution, required): Specifies whether to automatically log the start of each execution attempt. Options are **Always** (default) and **Never**
*   **LogLevel** (ModuleLogLevel, required): The severity for the module's automatic log messages. Only appears for **UiPath.System.Activities** 19.8.0 or older. For newer versions, it follows the global project settings for log levels.
*   **LogResult** (LogResult, required): Specifies whether to automatically log the result of each execution attempt. Options are **Always** (default), **OnException**, **Never**

**\- Automatic Retry Options:**

*   **NumberOfRetries** (int, required): The number of times the module tries to re-execute the code in case a non-BusinessRuleException is caught. In case of a BRE, execution is terminated without re-executing.
*   **RetryInterval** (TimeSpan, required): The amount of time between retries.

**\- Common:**

*   **ContinueOnError** (bool, optional): Specifies whether to continue execution or to re-throw the last caught Exception (is case of execution failure).
*   **DisplayName** (string, required): The display name of the activity. Cannot be empty or default, as it is used in the automatic logging.

**Out Arguments:**

**\- Output:**

*   **Result** (ExecutionResults, required): The result of the execution. Values are: **Success**, **BusinessRuleException** or **SystemError**

**Known limitation:** If the Work Module catches an Exception that does **NOT** originate in a different Workflow File, the exception source will be output as **System.Activities.**

The Work Module expands on the Workblock concept introduced in the Enhanced RE-Framework. It automatically logs execution attempts, catches exceptions and implements a retry mechanism
