Method for creating a sales slip

Abstract

In response to inputting order, a sales slip processor issues a sales slip with a slip code and a table code of a table at which the order is accepted, and stores order data in a sales holding file. In order to balance or rewrite sales slips, an operator inputs a sales slip code or a table code. The processor calls order data sets with a table code corresponding to the input code from the sales holding file and numbers the sets to create and store an edit data group in an edit file. One edit data set is selected and displayed on a screen display part. A data set next to the displayed edit data set can be retrieved from the edit file through one touch operation that designates a subsequent or previous slip with an input unit and displayed on the screen to thereby facilitate the retrieval of the order data with the same table code.

1 . A method for creating a sales slip for one or a group of customers on the basis of a plurality of order slips with a computer system, each of the order slips being assigned to a slip code, comprising the steps of:
 storing, in a memory device of the computer system, data sets of the order slips, each of the data sets being stored as a provisional data set;   inputting, with an input device of the computer system, a condition for designating a group of order slips;   retrieving, from the memory device with a processor of the computer system, a plurality of provisional data sets that meet the condition; and   organizing, with the processor, the plurality of provisional data sets as an edit data group, each of the plurality of provisional data sets corresponding to an edit data set of the edit data group.   
     
     
         2 . The method claimed in  claim 1 , further comprising the steps of:
 displaying, on a display device of the computer system, at least a part of the edit data group;   modifying the displayed part of the edit data group in accordance with operation through the input device; and   creating the sales slip on the basis of the edit data group including the modified part of the edit data group with the processor.   
     
     
         3 . The method claimed in  claim 2 , wherein:
 an order relation is given to parts of the edit data group; and   in response to an operation through the input device, a displayed part of the edit data group is switched to another part of the edit data group adjacent to the displayed part in the order relation.   
     
     
         4 . The method claimed in  claim 1 , wherein the condition is a customer code that is assigned to the customer or the group of customers and is included in each of the data sets of the order slips.
