Gantt: Add predecessor/successor relationship
You can use the Gantt chart to add a predecessor-successor relationship between nodes. There are two ways to do this.
Variant 1
- Activate “Auto-Schedule” under options
- Drag and drop the point from one atomic node to another with the left mouse button

Variant 2
- Double-click on the task on the left in the structure or on the right in the Gantt chart
- Open the tab "Linked tasks" and select "Add" zu add a predecessor-successor relationship.
- Select "Apply" to save the predecessor-successor relationship.
