Actual Fixed Cost Task Timephased Field. Project does not know how to spread the custom cost data. How Calculated Until actual progress is reported on a task with fixed costs the Actual Fixed Cost field is blank.

Actual Finish task field The Actual Finish field shows the date and time when a task or assignment was completed. How Calculated Until actual progress is reported on a task with fixed costs the Actual Fixed Cost field is blank. Im afraid custom fields are not timephased so they will not appear in any of the Visual Reports.

As you can see Remaining cost is same and Total Cost is33180 eg. Time Phased task fields show information for each task as distributed over its duration.
