During a quarterly finance review, you discover that several Looker dashboards display different values for Net Revenue because one team recently modified the calculation only on a single dashboard. You need to change the metric once so the updated definition is applied automatically everywhere it is used-across Explores, Looks, and dashboards-without editing each piece of content individually. Which Looker component should you update?
The Net Revenue measure defined in the relevant LookML view file
Each dashboard tile that displays Net Revenue, using the dashboard editor
The merge-results step that combines revenue and refund queries in affected dashboards
The field-picker label for Net Revenue in every Explore where it appears
Updating the measure definition in the appropriate LookML view file changes the underlying semantic model rather than the individual visualizations. Because LookML centrally stores business logic, any field that references the Net Revenue measure will inherit the new calculation as soon as the model is deployed. Editing dashboard tiles or Explore field pickers would localize the change and require repetitive manual work, and adjusting a merge-results step would affect only specific dashboards that use that merge.
