Subtasks come in handy when a strict control is required over complex and sophisticated tasks. Such tasks can be split into several simple ones thereby streamlining the task workflow. What is more important, the subtasks can be assigned to different employees which brings the flexibility of the underlying business process to a higher level.

How to create a subtask

There are several ways to add a subtask:

• When viewing a task click Add > Create subtask.
  


• When creating a new task click More > click Add in the Subtask of field and select a task that the new one will be the subtask of.
  


• In the Task list you can click the hamburger button and select Create subtask to add a subtask for the chosen task.
  


• You can right-click a task in the Gantt chart and click Create subtask.
  
You can make a current task a subtask of the other one in Gantt chart by clicking the arrow next to the task name. Make sure to enable Group subtasks and My sorting options.



The task that is above the selected task will become a parent task, and the selected task will become a subtask.

What happens when all the subtasks are completed

You may need to auto complete the parent task when all the subtasks are completed.

To do that, when creating a new task or editing an existing one click Options > enable the Auto complete task when all subtasks are completed (and vice versa) option.

Derive task dates from subtask dates

When you work with subtasks it may be important to calculate planned start and end date for the main task based on the dates specified for the subtasks.

To do that, when creating a new task or editing an existing one click Options > enable the Derive task dates from subtask dates option.

The start date (for main task) will be set to the earliest start date across all subtasks. The end date (for main task) will be set to the latest end date of the connected subtasks.
