Description: The built‑in Microsoft Gantt visual currently does not display a roll‑up bar at the parent task level when child tasks exist. As a result, parent tasks show hierarchy but do not visually represent the aggregated duration of their children. This makes it difficult to use the visual for high‑level project or work package reporting, especially in environments using AWP/WFP, portfolio summaries, or executive dashboards. Problem: When a task is structured as a parent and contains one or more sub‑tasks, the parent row collapses visually but the duration bar is missing, so there is no high‑level timeline representation. Users often need to communicate summary timelines without expanding all children. Impact: Prevents proper roll‑up of engineering, construction, or schedule data. Makes the visual ineffective for senior‑level reporting. Complicates dashboards for project controls and AWP workflows where parent‑level summaries are required. Requested Enhancement: Please add a “Show Parent Roll‑Up Bar” option to the Microsoft Gantt visual that: Calculates the parent bar using the earliest start and latest finish of all its children. Renders a summary bar (e.g., lighter color, dashed, bolded, or customizable). Works whether the parent row is expanded or collapsed. Supports conditional formatting and tooltips like normal task bars. Why this is needed: Roll‑ups are standard in planning tools (e.g., Primavera, MS Project) and are essential for summarizing phases, deliverables, or work packages. Power BI’s native Gantt visual would become far more usable for enterprise project reporting if parent‑level timeline roll‑ups were visible.
