Project Activities in Gantt View – Lightning Platform

The Gantt chart just got a major upgrade—Project Activities are now fully integrated into the visual timeline. To watch a video of the Gantt chart, see: i360 Production App with Gantt chart

Here’s what’s new and what you can do...

Project Activities Now Display in Gantt

You’ll now see Project Activities nested under each Project in the Gantt tab of Project Home.

Data Grid Columns (for each Project Activity):

Column Name	Represents
Name	Project Activity Name
Start	Project Activity Start Date
Duration	Duration (Working Days)
Assigned Staff	Assigned To
% Completion	Project Activity Completion (%)
Status	Project Activity Status
Health	Project Activity Health

🔧 Bug Fix: If a Project had a duration of 0 days, the Completion (%) field previously showed blank—this now correctly displays as 0%.

Edit Project Activities Directly in Gantt

Double click any Project Activity in the Gantt chart to open the edit panel. Edits are organized into three tabs, each with its own field group:

1. General (Field Set: Gantt Edit - General)

Project Activity Name
Assigned To
Completion (%)
Description
Health
Step Dependency
Step
Expected Duration (Days)

2. Dates & Hours (Field Set: Gantt Edit - Dates)

Start Date / Start Time
End Date / End Time
Duration (Working Days)
Duration (Working Hours)

3. Status & Completion (Field Set: Gantt Edit - Status)

Status
Completion Status
Completed
Completed On
Canceled
Canceled On
On Hold

Gantt Hover View for Project Activities

When you hover over a Project Activity on the Gantt chart, a tooltip appears with the following default fields (configurable via the Gantt Hover Field Set):

Project Activity Name
Start
End
Duration (Working Days)
Completion (%)

Gantt Tab on Project Record Page

A new Gantt tab has been added directly to the Project record page.

Shows Gantt for the current Project and its Activities only
Displays regardless of the Project or Activity status
The theme matches your app settings, even if changed
Data Grid: Enabled by default

View and Manage Dependencies

Project Activities now show dependency lines based on the Step Dependency field.

Dependency Features:

Hover displays: From → To Activity Names
Create, edit, and delete dependencies (with proper permissions)
System determines direction:
- "From" = earlier Start Date
- "To" = later Start Date
Validation prevents invalid links (e.g., can’t cross Projects)
Tooltip appears for unscheduled Activities
