Result
The project is transferred to MS Project. The objects in the R/3 Project System are mapped to objects in MS Project, as described in
Mapping R/3 Objects to Microsoft Project Objects.WBS elements are mapped as summary tasks in MS Project. Summary tasks always have subordinate tasks. In R/3 PS these subordinate tasks could be, for example, subordinate WBS elements or activities. If there are WBS elements in the R/3 project that do not have other WBS elements or activities assigned, they appear in MS Project as tasks, which correspond to activities in PS.
