Rollup

Rollup fields let you display values from tasks in other projects, based on an existing relation field. They're useful when you want to bring in information like assignees, due dates, or custom field values from related tasks into your current project.

How to create a rollup field

1. Create a relation field
   First, add a Relation field that connects to another project. This sets up the link between tasks in your current project and tasks in the related project.
2. Add a rollup field
   After creating the relation, add a Rollup field:
   • In the Relation dropdown, select the relation field you created.
   • In the Field dropdown, choose the specific field from the related tasks you want to display.
