You were just called by a colleague from the purchasing department. A purchase order for booking plane tickets to travel to Paris has been rejected for no obvious reason with a system message about the WBS element. You will check and modify the WBS element to be able to post the purchase order.
Status of a Project
A project has its own life cycle in between the defined start and end planned dates. A project begins when you create it and ends after you close it. During this time, costs are planned and posted to the included WBS element and settled to the receiving object.
Status management informs you that a particular phase in the project life cycle has been reached, and it controls which business transactions are valid at any given time.
The standard SAP S/4HANA includes four system status settings:
- Created
- Released
- Complete
- Closed

The system status allows only certain business transactions; for example, you cannot post actual costs in the status Created. Changing the status of a project is itself a business transaction and is done in the project master record.
The WBS element could have a different status than the project. However, it is not useful considering that for a simple overhead project there is always a single WBS element.
Note
In SAP S/4HANA Cloud, Private edition, and On-Premise, additional customized statuses could be used.
