This field specifies the minimum number of guests that need to be registered for the transaction for this charge to be applied. The system applies the charge line with the highest possible min. guest number and ignores the others.
For example, for two charge lines, one with min. 10, and the other with min. 15 guests, a transaction with 12 guests is charged by the min. 10 line, and a transaction with 15 guests is charged by the min. 15 line.
