reda.008 — Security Reference Data Update Request
The request to update a security's reference data: issuer, denomination, nominal currency, CFI classification, future events. Sent by the issuer or a participant to reference data providers (ANNA for ISIN, ESMA FIRDS for MiFID II reporting).
Purpose and place in the flow
reda.008 asks the reference data provider to update a security's reference data. Typical cases: change a fund's name (umbrella reorganisation), change of issuer LEI (merger, acquisition), correction of a CFI classification, addition of a future event (planned dividend, coupon).
Flow context: the issuer (asset manager, corporate, government agency) or its agent (paying agent, custodian) sends reda.008 to the central reference data provider; the provider validates, applies the update, and replies with reda.009. For ANNA (ISIN), the update is then propagated to every connected CSD via daily batch replication.
XML structure
reda.008 is wrapped in <Document> then the root
<SctyMntncReq>. Structure:
- MsgId — Unique request identifier + CreDtTm.
- UpdTp — Update type (UPDT, NEWM, DELM).
- FinInstrm (Financial Instrument) — Security data to update.
- FinInstrmId/ISIN + Nm — ISIN + name.
- Issr — Issuer (name, LEI).
- Ccy — Nominal currency.
- ClssfctnTp/ClssfctnFinInstrm — CFI classification (ISO 10962, 6 chars).
- SplmtryData — Free supplementary data (reason, context).

Common pitfalls
- Inconsistent UpdTp — an UPDT without an existing security is rejected; a NEWM on an already-present ISIN is rejected. Check the reference data state before sending.
- Invalid issuer LEI — the LEI must be valid and active at the time of the request. An expired LEI (annual renewal mandatory) is rejected.
- Proprietary ISIN — ISINs are assigned by ANNA via NNAs (National Numbering Agencies). Trying to reserve an ISIN through reda.008 without going through the NNA is rejected.
- Malformed CFI — CFI classification strictly follows ISO 10962 (6 chars, each position with defined values). A CFI error blocks validation.
- Retroactive update — a name change must have an effective date ≥ today. No back-dating possible to preserve past transaction consistency.
- Delayed propagation — the update applied centrally takes 24-48h to propagate to local CSDs. Plan a transition period where both names coexist.
