Actual Material Cost
The actual material cost is the amount of material cost generated when the milestone is nominated.
On the Estimate Revenue Milestones and Revenue Milestones forms, the Actual Material Cost field is in two places: on the General tab and on the Audit tab.
On the Estimate Revenue Milestones form, the Actual Material Cost field is always blank because costs are not generated for estimate projects.
On the Revenue Milestone Nomination form, the actual material cost displays from the Revenue Milestones form, but you can override the amount.
