When you use a main project to group many subprojects, even small changes to a subproject can trigger recalculations for the entire project. This can significantly slow down performance. To avoid this, we recommend not using unnecessarily large composite projects. Consider detaching the main project if subprojects are independent. |
The project calendar defines the working hours for a project. All the WBS items will be planned based on the working hours defined in this calendar including the time intervals in dependencies that also consider the project calendar working hours. |
