Action
The Action activity allows you to assign a task to a user within the workflow.
Purpose
Use the Action activity when you need to:
- Assign manual work to a team member
- Create tasks that involve external systems (e.g., "Send an email to somebody")
- Track completion of activities that don't directly interact with application data
Configuration

Name
- Activity Name: Unique identifier for this action in the workflow
- Used to reference the activity in workflow design and execution logs
User Instructions
- Instructions Field: Large text area for detailed instructions
- Provide clear, step-by-step guidance for the assigned user
- Supports multi-line text for comprehensive task descriptions
Files & Links
Add supporting materials to help users complete the action:
- New File: Attach files from the application for reference
- New Url: Add links to external resources, documents, or systems
- Files and links appear in the action view for easy access
Due Date Type
Configure when the action should be completed:
- None: No deadline specified
- Fixed Date: Set a specific due date
- Relative: Set deadline relative to workflow start or previous activity
Owner
- User or Security Group: Assign the action to a specific user or group
- The owner is responsible for completing the action
- Only one owner can be assigned per action
- Click the icon to browse and select from available users and groups
Contributors
- Add Multiple Contributors: Users who can assist with the action
- Contributors can view and work on the task alongside the owner
- Click + New Contributor to add users or groups
- Useful for collaborative tasks
Supervisors
- Add Multiple Supervisors: Users who oversee the action
- Supervisors can monitor progress and completion
- Click + New Supervisor to add users or groups
Advance Rule
Determines when this activity is triggered based on predecessor activities:
- When All: Activity starts only after all predecessor activities complete (default)
- When Any: Activity starts when any predecessor activity completes
- When First: Activity starts the first time any predecessor completes, then ignores others
Usage Notes
- The action is a simple task assignment with no predefined outcomes
- All other interactive activities (Approval, Report, Data Input) build upon the Action activity
- Best suited for tasks that require human intervention outside the application
- Use clear, actionable instructions to ensure task completion
- Attach relevant files and links to provide context
Best Practices
- Clear Instructions: Write detailed, step-by-step instructions in the User Instructions field
- Appropriate Assignment: Assign to users who have the skills and access needed
- Include Context: Add files and links that provide necessary background information
- Set Deadlines: Use Due Date Type when timely completion is important
- Use Contributors: Add contributors for tasks that benefit from collaboration
- Add Supervisors: Include supervisors when oversight or approval tracking is needed
