Create Plane Sub-Work Items Without Losing the Parent Link
Use Add sub-work item on a Plane parent to create independently tracked children, or attach existing work. Each child retains its own assignee, state and dates.
You need permission to edit the parent and create or link the child work. Governed work-item hierarchy can restrict which child types are allowed.
Example: break Checkout retries into API behavior, error messaging and verification items while keeping a single parent outcome for release review.
Step-by-step guide
Open the outcome parent
Find the work item representing the deliverable and check its existing children. Avoid creating a second parent for scope already tracked elsewhere.
Create the first child
Click Add sub-work item beneath the description and choose Create new. The creation modal sets the current item as parent; write a concrete deliverable and assign its owner.
Link existing implementation work
Choose Add existing for work already tracked. Search across projects if necessary, select the correct record and verify that its type fits any governed hierarchy.
Review the child list
Inspect the Sub-work items progress and visible fields. Open a child to confirm the parent appears above its title, then review independent dates and state.
Common mistakes
Deleting a parent as cleanup
Deleting a parent also deletes its sub-work items. Remove a child’s parent first if that work must survive independently.
