Subject description
The objective of the application is to facilitate definition of margins by combining the required steps for calculating scenarios (for the combination of contracts) in an application. Instead of the previous method of calculating one scenario with purchasing contracts and one scenario with sales contracts (i.e. to determine prices, quantities and sales per contract), "margin determination" makes it possible to combine a purchasing scenario and a sales scenario into a "margin scenario". Comparison of the settlement results for the purchasing and sales scenario is performed using MS Excel.
