Typically, a bank statement received from a bank includes a large number of transactions of different types, such as outgoing payments, bank transfers, and deposits. Internal bank operation codes are used to determine the type of each transaction row in the bank statement. Each row in the bank statement must be identified by an internal code defined by the company. If you add a statement row manually, make sure you include such an internal code. Optionally, you can enter an external bank operation code list associated with that bank to identify the relevant internal code to SAP Business One. Based on the internal code, SAP Business One creates the correct transaction for each bank statement row when the bank statement is finalized.
