When you create a work breakdown structure, you must also enter a project profile for the project.

The project profile contains default values and parameters for processing the project, for example, which settlement schema is valid, which factory calendar is used for time scheduling, or which settings are used for graphics.

You can maintain the values for the project profile in Project System Customizing.

If you create a work breakdown structure, the project profile is saved in the project definition. You can change default settings from the project profile when you are working with the work breakdown structure.
