General Instructions Information may be entered by accessing the website (https://www3.bcra.gob.ar) and identifying with the user code and single password per entity as provided in Section 1. of Submission of Information to the Central Bank, according to what is established for the file transfer service on www3 (MFT). In the case of financial entities, non-financial credit providers, financial trusts and peer-to-peer credit service providers through platforms will save a file named “RECTPARC.TXT”, while mutual guarantee companies and public guarantee funds will save a file named “RECTPARCSF.TXT”. One file may be entered per day containing a maximum of 250 records. To identify this regime/requirement (61.1. PARTIAL RECTIFICATIONS) the regime code “00002” and requirement “00005” must be used for financial entities, non-financial credit providers, and peer-to-peer credit service providers through platforms; the regime code “00002” requirement “00011” for mutual guarantee companies and public guarantee funds; or the regime code “00002”, requirement “00012” for financial trusts. A record must be reported for each information period that corresponds to being suppressed or rectified from the records of each debtor. This plain text file will be of variable length, according to the corresponding record design, and taking into account the following specifications: a. Character encoding must respect ANSI – 1252. b. The symbol “;” (semicolon) will be used as a field separator. c. To separate each record, the application generating the TXT file used by the entity must symbolically indicate the hexadecimal characters representing a <CR> “Carriage Return” and a <LF> “Line Feed”. This means that an <Enter> is generated at the end of each record. d. The last field of each record MUST NOT contain the symbol “;” at its end. That is, the number of “;” per record equals the number of expected fields minus 1. e. It is not necessary to complete the field up to the maximum expected length (i.e., fill numerics with 0 on the left or alphanumerics with blank characters). f. If a field is not to be reported (value “NULL” or absence of value), the field separators (“;”) must be completed successively without intervening blank spaces. (Applicable exclusively for suppressions). B.C.R.A. SUBMISSION OF INFORMATION TO THE CENTRAL BANK Section 61.
