Dear Dawn
Please check the price control in mm02 of 5* materials, it should be 'V' If you want to ignore 5* materials during costing run you can mark them 'DO NOT COST' by ticking indicator at costing 1 tab of material master. Thus the individual materials will not be costed during costing run but their cost will be included in costing of FG material.
