when you make a request in CA Catalog 12.7 all costs of the elements are summed up and shown as total costs regardless whether the costs are one time only payments or periodical costs.
For example we request a service with 3 elements:
Element 1 one time 20€ + monthly 5€
Element 2 monthly 15€
Element 3 one time 20€
The total costs are shown with 60€.
The real costs for one year would be 280€. Therefore I' be better to show the costs like that:
total costs: one time 40€
