Pricing for special customers

The customer receives spare parts at the cost price + a fixed percentage of the cost price. This simple pricing rule cannot currently be mapped as such. The calculation method implemented in the systems requires a list price to be present. Special conditions are included via the spare part's sales area; these conditions are used to calculate the cost of sales. The new calculation is initially structured with one rule only (the surcharge rule). The surcharge factor can be adjusted for each customer. The new method checks whether the transaction involves a customer calculated using the surcharge rule. If so, the surcharge is identified via the customer number and the calculation is carried out. Otherwise, the item is priced according to the existing rules.
