}File the compulsory statement (RCO0002)
Files the compulsory statement for a calculation period: one or more days, each carrying its incidence items. Every day must fall inside the declared period — a day outside it is refused here rather than spent on a round trip BACEN would reject. The requirement BACEN computes from the filing arrives on the answer and lands on the period row. Idempotent on X-Idempotency.
