Position Folder is a document describing a logistics service for a particular company: company name, description of goods, contract number, date, value in currency, consignor... The key information is the position number. Whenever we need all of the above mentioned information related to a company (e.g. in an invoice), we just refer to the position number containing all of the necessary data, which we do not have to re-enter again. In this way, the documents are interconnected through a position number - just as in practice: all documents relating to a position are inserted in a common "position folder".
