Re: Number of assigned resources on tasks

This is applicable to project server, where resources are managed at organization level ( program or portfolio) . Where resources are allocated to different tasks and possibly to a different project , then project server will show you availability of all the resources and you can choose which one to assign, of course after approval and it reduces the availability of that resource automatically. In stand alone projects not all resource times dedicated to project related tasks hence best bet will be to update resources sheet and the individual availability then assign them to tasks, look for any over allocation and resolve that by resource levelling.

Polestar2021,
Using the Assign Resources sub-window as shown in the image you posted is the best way to assign resources while in the Gantt Chart view. Unfortunately, the list of resources is ordered by whether assigned or not. That is, assigned resources start at the beginning of the list and unassigned resources fall to the bottom of the list.

You could also click on the selection arrow in the Resource Names field. You will see all available resources listed with a check in the box next to each that is assigned. This presentation is not sorted so it is a bit easier to see which resources are not assigned. However, checking a resource's box will automatically assign that resource at 100%.
