The manual prevails
- Source. The official manuals of BACEN and of the market infrastructures (Núclea, B3, Selic) define each message, its fields and its cut-off times. A manual does not define the order between messages, so the order shown here is a suggested reading.
- Conflicts. If this site and a manual disagree, the manual prevails.
- Responsibility. Your institution is the participant. It validates each flow against the manuals in force and decides how to apply it to its operation.
- Support. Lerian supports its own products and APIs. Advice on applying the manuals to your operation is a separate service: Lerian offers workshops and consulting by proposal. Contact your Lerian account team.
