Project types

A main project is a separate project that is made up of several subprojects. Main projects and subprojects are both defined as projects. A main project acts as the driver for the planning of its subprojects or as the aggregate for the financial results of the subprojects. Recording a project structure using main projects and subprojects is especially important for extensive projects in an engineering-to-order situation. For main projects, only a limited number of project control functions is feasible.

A subproject is part of a main project. The network planning for the subproject is derived from the planning for the main project. Several parameters can be defined at main project level for a subproject. The project control functions for a subproject are also applicable for the single project.

A single project is a separate project that is not divided into several subprojects.

A budget is used for planning and estimating, not for production execution.
