Administrators have to specify company-wide app settings, setup default values for new charts, and configure Jira fields that are used by Gantt Suite.

App configuration is accessible from Jira settings → Apps → Gantt Suite → Configuration:

Configuration

Gantt settings

Gantt settings, defined in Gantt Suite configuration, are the default values for the new charts. Existing charts aren’t affected by the changes.

Here, administrator can select the default fields for the task start and/or task end and the task deadlines.

Resources

Here, administrator can set the default values for the new charts in regards to working days and hours for a team in whole.

Basically, the same configuration regular users see when creating a chart Resources configuration

Links configuration

The values defined here by administrator are the default values for the new charts. Existing charts aren’t affected by changes.

Basically, the same configuration regular users see when creating a chart Links configuration

Task progress

The admins define a default behavior for the Time tracking checkbox.

Permissions

In addition to the app configuration, the admins configure the app permissions such as app visibility, chart creation, screen field check and impersonated view.

App visibility

By default, all Jira users are granted permission to see "Gantt" in Jira's top menu and access the app. Select specific groups in case you want to limit the app access.

Chart creation

By default, all Jira users who are granted permission "App visibility" can create a chart. Select specific groups in case you want to limit the chart creation ability.

Screen field check

This settings was added to the app’s server version, starting v2.2.x.

By default, there is no verification if configured field is present on project's screens.
Therefore, a user might be able to set a value for a field that is configured for Gantt chart but is not present on Create/Edit issue screens of configured project.
Should you prefer to prevent such behavior, please make sure to check the checkbox 'Screen field check'.

Allow impersonated view is NOT a default value. It affects all charts, existing and new ones. The option is only visible to Jira administrators.

Normally, users without permissions to access projects or issues will not see them on a chart neither. This option lets chart creators to allow users with restricted access to see the tasks on a chart in view-only mode. In other words, it allows users with restricted access to see chart the way chart owner does.

When this company-wide option is turned on and chart creator also turned impersonation on, app impersonates as chart creator for Jira issues and links loading. All other operations are NOT using impersonation.
