New input field for "Prepayment 3" (Reference Data/ Hostels/Hotels, Page Payment/Terms). After every alteration, the system calculates the amount newly. This was intended for a complete payment before arrival. Instead of a "Y", a number for calculation of the prepayment can now be entered in field "regcode" in the settings. If the date is closer than the entered number of days before arrival, a prepayment is not necessary. If the date is closer than 14+x days before the next prepayment, it is also been removed. This way, it is avoided that more payments have to be made directly after each other for multi-level systems. If a prepayment of 0% has been stored in the reference data, the system automatically calculates the prepayment per person via a fixed amount (article) which can be stored in the meal plan (only prepayment 1 and 2).
