Definition
Structure element of the work breakdown structure (WBS). A WBS element describes either a certain task or a partial task that can be subdivided further.

According to DIN 69 901, those elements in a work breakdown structure that are not subdivided are referred to as "work packages".
In the Project System, a work package is not a data object. A work package can be represented in the SAP System by a WBS element or an activity.
