A figure in a regulatory return you already submitted turns out to be wrong. What happens next, and what should the system have been built to do?

Answer
Short answer
You quantify the error, decide materiality, tell the supervisor and resubmit with an explained delta. Building for that means an immutable snapshot of what was submitted, a re-run that reproduces it exactly, per-line lineage back to the ledger, and completeness asserted against a declared manifest rather than assumed.
Regulatory reporting ownership should make the correction auditable from defect to resubmission. Regulatory reporting teams also need to prove the restatement scope is complete.

- The same error affects three returns with different cut-offs. How do you scope the restatement?
- What would make you decide an error is not worth resubmitting, and who owns that decision?
- How would you stop the same class of error from recurring without adding a manual check?
