Whenever any of the five possible price per unit values changes for a resource or role already assigned to activities, run the Recalculate Assignment Costs feature. This feature recalculates any changed assignment costs.
You should also run this feature during scheduling or leveling because dates will change and resources might be using time varying rates. This means their activities can shift into periods with different effective prices. Therefore, the costs would have to be recalculated.
The Recalculate Assignment Costs feature only applies to currently open projects. This provides project managers with control over recalculating costs only when prices have changed.
When another user changes prices for resources or roles, P6 will display a message indicating that the Recalculate Assignment Costs feature should be run in order for project assignments to use the new values.
This feature can be run at any time from the Activities page or scheduled as a service.
