After you consolidate files into a master project file, the tasks from subprojects files remain separate, resources are combined from all subprojects.

You can change resource information in the master project and the changes will be replicated in the subproject’s source file.

You can view all resources in the master project and subprojects together in the Resource Sheet view, the resource can be edited /assigned.

If the same resources are used in multiple subprojects, you see the resource names just once because the resources are combined. However, it is recommended to use organization Team Members, then assign the resources in different subprojects.

Keep in mind that if you use the same resource in multiple projects, in Master Resource Sheet will appear one resource. If that resource uses different Std rate values in the subproject source file, the Master Project file will calculate an average value based on std rate value and cost per use.
