When you work with subprojects, a task of a project is created as a separate subproject, for example, because a different department or a subcontractor is responsible for the task. To map this relationship, you create an inter-project link between the task of the master project and the project definition of the subproject.
A task of a master project can only ever be linked to a single subproject. The subproject can, however, also be the master project for other subprojects which enables you to map multilevel project hierarchies.
The following graphic explains the scenario:
A task that represents a subproject must not contain any subtasks in the master project. Apart from this, it behaves like a normal task that you can process and confirm.
· Your system administrator has permitted the use of subprojects for the current project type (see Customizing for Collaboration Projects, IMG activity Define Project Types).
· You have at least display authorization in the subproject.
· You have entered persons responsible for the task in the master project and for the project definition of the subproject (see Creating Basic Data for a Task or Creating Basic Data for a Project Definition).
· Note the prerequisites under Alerts if you want the system to be able to inform the responsible persons about changes.
When you create the inter-project link, the project lead of the subproject receives a message to inform him about the inter-project link. The message contains the dates for the task that belongs to the master project. The project lead can adjust the dates of the subproject manually; there is no automatic adjustment.
Messages are also sent in the following cases:
· If a date is changed in the master project or subproject
· If the master project or subproject is deleted
· If the inter-project link is deleted
A task that represents a subproject is shown by the following icon in the project structure of the master project: Task for Subproject. An additional area that contains information about the master project appears on the Basic Data tab page for the project definition within the subproject (see Creating Basic Data for a Project Definition).
1. Create a task that you want to represent a subproject or navigate to a task that already exists.
2. On the Basic Data tab page, enter the number of the subproject that the task is to represent.
When you save, the system creates the inter-project link and displays the name of the subproject. You can display the subproject data by clicking the name of the subproject. If you have authorization to edit the subproject, you can switch to change mode after you have opened the subproject by choosing Display/Change.
3. To delete the inter-project link, delete the entry under Subproject.
