Import each statement as a retained batch
Reuse the same CSV source for each later statement. Enter the inclusive statement period before upload, review the preview, and confirm only after the period, mapping, template version, currency, and row summary are correct.
- A later non-overlapping period is accepted on the existing source.
- An exact replay or an inclusive overlap with an accepted batch is rejected.
- Import History keeps the period, file fingerprint, template version, counts, retry lineage, finalization time, and audit event.
- If a legacy completed batch has no period, classify it once from Import History before continuing.
