My task's total costs changed unexpectedly

Symptoms

The total costs for your task changed unexpectedly as the schedule progressed.

Cause

The task's total costs may have changed due to a task or resource schedule change that occurred, even though you have not entered new costs or updated the existing costs.

Resolution

• Verify the effective dates of resource rate changes that you set in the cost rate table in the Cost tab of the Resource Information dialog box. A rate change that you set to occur at a specific date may have gone into effect.

• Verify the start date and end date of a task that you moved. If you moved a task into a different time frame, a different rate you set for that time frame may have been applied.
