Structure the tasks hierarchically as required by moving them to the required position by holding down SHIFT + left mouse button.
- Select the Generate WBS code command from the context menu by right-clicking on the project header or by clicking on the Generate WBS code symbol (on the left hand side below the project header).
- The WBS code is generated automatically for every task in the WBS Code field in accordance with the structure. Thus, the WBS code is both an identifier for single elements in the schedule and an indicator of the hierarchical structure.
- Start the calculation of the schedule by clicking on the Calculate schedule button in the toolbar.
- As a result, all parent tasks are marked bold and are therefore visualized as summary tasks.
- If changes have been made to the task structure since last updating the WSB codes, the codes are updated as well when the schedule is calculated.
