When you upload a rate sheet, it goes into a staging area — a holding zone where you can review it before it affects real quotes. Think of it as a draft.
What "Effective From" meansThis is the date from which the new rates start applying. Quotes before that date use the old rates. Quotes on or after that date use the new rates.
Past dates are blocked. You cannot approve a rate sheet with an effective date in the past, because doing so would retroactively change historical quotes — which are permanent records.
What happens after approvalRows flagged as anomalies have prices that look unusually high or low compared to surrounding rows. Review them carefully before approving — do not approve a rate sheet with unexplained anomalies.
