Use this tab to view the figures of the different cost buckets from standard cost calculations, order cost estimates, and actual costs. There are six different variances using both level and accumulated costs, resulting in a total of twelve variances presented. The variances are presented both as factors and figures with a sum total at the bottom of the table. The summation, denoted by the sigma sign at the bottom of the table, allows for an overview of all cost variances for the specified shop order.
