Subtasks

What are subtasks?

• hierarchy: Child tasks nested under a parent to structure work
• roll‑ups: Parents aggregate dates and progress from their children
• flexible links: Subtasks can have predecessors like any task

Levels and limits

• level 0: Top‑level tasks (no parent)
• level 1+: Children at increasing indent levels
• max depth: 6 levels

Creating subtasks

• toolbar: Select a parent → Add dropdown → Subtask (or press S)
• indent: Select a row and press Tab to make it a child of the previous non‑milestone row
• fallbacks:
  • No selection: creates a top‑level task
  • Selected parent is a milestone: creates a top‑level task (milestones cannot be parents)
  • Insert position: placed after all of the parent’s existing children

Indent and outdent

• indent: Moves the row (and its contiguous children) under the previous valid row; new level = min(prev.level + 1, 6)
• outdent: Lifts the row one level; its actual children follow, preserving relative depth
• milestones:
  • Cannot become parents; indent uses the previous non‑milestone as parent
  • Outdent avoids creating milestone parents; if it would, the outdent is skipped for that row

Scheduling and roll‑ups

• dates: Parents roll up from children earliest child start, latest child finish, duration = business‑day span
• progress: Parents compute percent complete from immediate non‑milestone children
• business hours: Edits normalize to working‑day times; weekends are skipped
• critical path: Subtasks participate in CPM like any task

Tips

• Keep depth to 2–3 levels for readability
• Use parents to represent phases; children for actionable work
• Avoid adding children to milestones use a regular task instead

FAQs

Why can’t I add a subtask to this row?

It’s a milestone. Milestones can’t have children.

Why don’t parent dates match what I typed?

Parents roll up dates from children. Edit child dates to change the parent.

How do I move a subtask to a different parent?

Use Indent/Outdent (Tab/Shift+Tab) or reorder, then re‑indent.
