Break-weight calculation is required for several shipment contracts. In break-weight calculation, the system calculates at what weight onwards the price becomes cheaper, in order to get to a higher and more reasonable pricing scale level.

During break-weight calculation, the use of two condition types is necessary. The first condition type is used for "standard" calculation of the shipment costs. The second condition type is used for calculation of the shipment costs at the next higher scale level. Now the system compares the two calculated values using a type of exclusion procedure and takes the most reasonable value as the price.

You create the second condition type with a reference to the first condition type (can be set using the fields Reference condition type and Reference application). The second condition type, therefore, uses the same condition records as the first condition type. When you assign the scales, select the break-weight indicator only for the second condition type. This indicator has the effect that, when the shipment costs are calculated, the next higher scale level is used for the calculation. Therefore, two calculations take place: in the "standard" way" and at the next higher scale level. With multi-dimensional scales, you set the indicator in the scale where the break-weight is to be calculated (in the case of a condition type that contains a distance and weight scale, for example, you could set the indicator in the weight scale). When the shipment costs are calculated by the system, it compares the costs. For this purpose, you need to define a condition exclusion group, assign both condition types to the exclusion group, and then specify the exclusion procedure. The cheaper cost between the condition types. You then assign the exclusion procedure to your calculation procedure.
