The following error is obtained when the "Populate from Assignments" option is used in a Cost Plan.
ERROR: REVMGR-20728:Rates/Costs are missing for following roles/resources
While looking at the Rate Matrix, it is noticed that rates are defined for all the relevant roles and resources.
Cause
The rates defined in the matrix do not cover the investment time window. That is, the period between the start date of the project, and the end date of the project.
Resolution
Points to consider with respect to Rate Matrix
When populating from Allocations or Assignments there needs to be a rate in the matrix to cover the whole range of the investment dates not just the resource team dates, or resource assignment dates.
