You can update a cost or charge rate in the hierarchy by a fixed percentage or value. You can change the rate for a single resource or for a whole hierarchy level. If you update the rate for a level, you can also choose to update all resources and/or levels in that level.
Open: Project Accounting > Project Maintenance > Hierarchy.
Click Update Rate.
The Update Charge Rate window appears. The Description shows the name of the rate to be changed.
To update the rate in levels below this level in the hierarchy, enable Cascade update to sub levels.
Note: This will not adjust the rates for resources with a level unless Update Resources is also enabled.
