2. Particular Instructions 2.1. Automation of new registrations, modifications, and corrections for rejected or reported checks (according to the design inserted in point 3.1 of these instructions): 2.1.1. A rejected or reported check will be initially registered (new registrations), and subsequently, specific data may be incorporated into it only once (modification). This latter alternative is restricted exclusively to the following items for rejected checks: check payment date, fine payment date, and account closure date. For reported checks, only the presentation for collection or registration date may be modified. 2.1.2. When it is necessary to correct a previously reported data point via an initial registration, modification, or prior correction for rejected and reported checks, the design must be completed by filling field 6 with R for rejected checks and N for reported checks. This alternative is restricted to the following items for rejected checks: notice year, notice number, notification date, cause, original currency amount, rejection date, registration date, check payment date, fine payment date, and account closure date. For reported checks, it is restricted to the following items: notice year, notice number, reporting date, cause, presentation for collection or registration date. These movements generate operational expenses exclusively for rejected checks (point 6.4.7.3 of the Bank Current Account Regulations). 2.1.3. It should be clarified that the system does not allow modifying or correcting fields related to check identification (Entity Code, Branch Number, Account Number and/or Check Number), nor the Currency Code field, nor the Check Type field. Therefore, if correction is necessary, the record of the incorrectly identified check must be deregistered using reason code B 33, followed by a new registration with the correct data. 2.1.4. New registrations must necessarily include the following data: i) Rejected checks: Entity Code, Branch Number, Account Number, Check Number, notice year and number, movement code, registration class, notification date, cause (1, 2 or 3), currency code, original currency amount, rejection date, check type, CUIT, CUIL, or CDI number. At least one individual tax identification key must always be registered. ii) Reported checks: Entity Code, Branch Number, Account Number, Check Number, notice year and number, movement code, registration class, reporting date, cause (6, 7 or 8), CUIT, CUIL, or CDI number. At least one individual tax identification key must always be registered.
