Asta Powerproject - Linking tasks
A common link is a Finish-to-Start link, where one task (the predecessor task) must finish before another task (the successor task) can start.
To draw a Finish-to-Start link between two tasks:
- Position the mouse pointer over the bottom-right of the second task on the Site Planning bar so that the cursor changes to
, indicating that the link will start from the finish of the task.
- Hold down the left mouse button and drag the cursor away. Notice that you now have a line from the finish of the task to the cursor. The line is attached to the cursor until you release the mouse button.
- Position the end of the link on the top-left hand corner of the Construction task so that the cursor changes to
, indicating that the link will finish at the start of the task, and release the mouse button. A link is drawn between the two tasks:
- Click on a blank area of the bar chart to deselect the link.
You can draw links with lead/lag, indicating that there must be a delay between tasks:
- Position the mouse pointer over the bottom-right of the Fabrication task.
- Hold down SHIFT and, using the lead/lag popup and the date zone as a guide, click and drag the cursor two working days (ie, two weekdays) to the right of the finish of the task.
- Keeping the mouse button depressed, release SHIFT, then position the finish of the link on the top-left hand corner of the Completion task and release the mouse button. A link is drawn between the two tasks with lead/lag:
The straight part of the link indicates the lead/lag time. You can edit the lead/lag time precisely by double-clicking the link and editing its properties.
- Click on a blank area of the bar chart to deselect the link.
- Complete your linking by drawing a simple Finish-to-Start link between the Construction and Completion tasks.
Your project should now look something like this:
