Hi
A <b>work breakdown structure</b> is a model of a project, and shows the project
activities to be carried out as a hierarchical structure. The various work
packages in the project are described in individual work breakdown structure
elements (WBS elements). You can further divide these elements at various
levels until you reach the level of detail you require. The focus here is on planning, controlling, and analyzing costs, basic dates, and budgets. Because the work breakdown structure is structured hierarchically,the data can be summarized and displayed for the corresponding higher-levelWBS elements. When you create a work breakdown structure, you also have to create a project definition..
<b>
Networks</b> map the flow of the project. The focus here is on describing,
planning, controlling, and analyzing costs, scheduled dates, resources, and
material requirements. The basic elements that go to make up a network
include activities and relationships that describe the tasks and temporal
dependencies between the various tasks in a project. SAP Project System
supports the following activity categories:
• Internal processing: for capacities to be staged in your own company
• External processing: for tasks to be assigned externally
• Service activities: for procuring external services
• Costs: for planning additional primary costs
In the Project Builder, you create activities for WBS elements. This means that the activities are assigned to the WBS elements in question. It also means that the planned and actual data for the activities (dates, costs, payment data) can be aggregated at WBS element level. A network always includes a network header that contains the control data and default values for the entire network.
