PURPOSE:To enlarge a set sales operation by executing a discount processing when the number of groups where a set is realized coincides with a previously set numeric value. CONSTITUTION:When data is stored in a set sales work table 34, it means that it is the termination instruction of transaction where there is the purchase of commodities being the object of set sales. Thus, the work table 34 is referred to and the number of records (c) where a realization flag (f) is set (1) by individual set numbers is counted. When the number of the records (c) coincides with the group realization number of the set numbers concerned which are set in a set table 33, the realization of set sales by the combination of the set groups to which the set numbers are commonly given is judged. A realized price total value is subtracted from the sales sum total value of the records becoming the object of set sales realization so as to obtain a discount value. Then, it is added to a discount amount total unit 36. Then, the content of the discount amount total unit 36 is subtracted from the content A of a sales amount total unit 35 so as to obtain the amount of payment. |
