In Adobe Workfront, Planned date-based calendar reports are commonly used to visualize project timelines, milestones, and deadlines. They help teams plan and manage workloads based on dates and other time-related factors.
Filters with custom grouping allow users to customize their reports by organizing data in a meaningful way, tailored to specific project or team requirements. Custom groupings enhance the clarity of reports by categorizing data based on selected criteria.
The other options are not correct because Workfront does not support reports that reference multi-select custom fields in a chart format, nor does it allow object names longer than 500 characters.
