This field applies only if the RES_TYPE property is of type MaterialResource. The Material Label field contains the unit of measurement you enter for supplies or other consumable items that are used to complete tasks in a project; for example, tons, boxes, or cubic yards. This label is then used in conjunction with the material resource's assignment units; for example, eight tons or 22 boxes.
