It is possible to create, edit and delete versions in WBS Gantt-Chart. However, only users with the following permissions can do this.
Creating a version
When you create a version in WBS Gantt-Chart, you need to have the following configuration in the WBS Gantt-Chart display settings.
No version is not selected.
Exclude versions that do not have subordinate issues is not checked.
You can create a version from the contextual menu or from the operations toolbar.
To create from the contextual menu
Right-click on the project.
Select Add ... ⇒ Version.
To create from the operations toolbar
Select the project row.
Select Add ⇒ Version on the toolbar.
The name of the created version is "Version of project name".
Also, the start date / release date is set as the date of creation (when the initial planned date in the issue configuration is set as the date of creation).
Editing a version
You can edit the name, start date and release date (finish date) of versions on the WBS display. To edit a version, double-click the item in the WBS display, or drag the Gantt bar.
Deleting a version
As with creating a version, you can delete a version from the contextual menu or from the operations toolbar.
To delete from the contextual menu
Right-click the version.
To delete from the operations toolbar
Select the version row.
Select Delete ⇒ Version on the toolbar.
If you delete a version, any issues which are subordinate to the version will not be displayed on the WBS display. Please reload WBS Gantt-Chart to see them again.
