If you did not indicate the construction links required between manufacturing/delivery tasks and construction tasks, you can add them with this button.
It searches for contract award tasks and all manufacturing/deliver tasks that do not have a construction work successor and displays them one by one for you to create links between them.
The first construction task of the subcontractor will be selected but you can choose another one or multiple selections using Ctrl on your keyboard.
You can choose another subcontractor task or even a procurement task by clicking on the All tasks button.
Click on the Next button to continue, if you want to do it later you may by clicking the Suspend button.
This window will appear to tell you that you have not finished linking all the procurement tasks to one or more construction tasks.
If all links exist it will tell you too.
