Coherence - internal

Calculation of cost developments are done separately for each product. Developments of each product in a product group may be based on different amounts or units, i.e., if the price of half a kg of product 1A rises by 4 pct. while one kg of product 2A rises by 6 pct., the total price development of products A is 5 pct., regardless of the individual weights.
