APPARATUS, METHOD AND COMPUTER READABLE RECORDING MEDIUM FOR CALCULATING RECEIPTS AND PAYMENTS AUTOMATICALLY USING AN INVERSE OPERATION

摘要

The present invention relates to a system for generating a materials ledger using inverse operation and determining country of origin, which is capable of automatically and readily calculating a materials ledger for company in a company using the inverse operation. In particular, the system comprises: an information collection and management unit for receiving item information, bill of material (BOM) information, raw material purchase information and product sale information and storing the received information in a base information database; a materials ledger for raw material generation unit for inversely computing the amount of raw materials input to the production according to each setting mode through base raw material information on a predetermined base date, the raw material purchase information stored in the base information database, the product sale information, and raw terminal unit amount information to generate a materials ledger for raw material; and a materials ledger for product generation unit for inversely computing the amount of products stocked after the production according to each setting mode through base product information on a predetermined base date and the product sale information stored in the base information database to generate a materials ledger for product.
