Rules and consistency checks

Per investment pool (investment.pool): refKey, description, currencyType, buySellId (buy or sell) and tradeValueAmount, the net cash effect. Numbers of units and unit values are not in message 10 but in message 13.
Release 2027 removed the cohort-pool layer; the data lands directly on investment.pool. The fields dummyCashId, tradeQuantity, unitPrice and currencyExchangeRate have been dropped (issue #133).
The message must reach the fiduciary at T-4; late means the execution window (T to T+3) is missed.

Pitfalls

Messages built with the Release 2026 schema contain the pensionCohortPool layer and are rejected by a Release 2027 receiver (unknown field).
Issue #92 ('SIVI 10 sell units'): a sale is expressed with buySellId = sell and positive quantities, not with a negative quantity.

Errors and fixes

messageId missing, empty or longer than 70 charactersSchema error on commonTechnical/0/messageId: 'must have required property' or 'must NOT have more than 70 characters'.
Duplicate messageId after acceptance (HTTP 400 with feedback)The receiver answers HTTP 400 with a feedback message (statusType 0) to a message that looks correct in content.
afdDefinitionName incorrect (a fixed value since the final Release 2027)Schema error 'must be equal to constant' on afdDefinitionName; the WTP Data Lab validator names the expected value. Typical of a message built on the July 2026 pre-release: it states the right version 001.05 and still fails.
afdDefinitionVersion incorrect (001.04 versus 001.05)Schema error 'must be equal to one of the allowed values' on afdDefinitionVersion, or the receiver validates against the wrong schema and reports unknown fields.
buySellId invalidSchema error 'must be equal to one of the allowed values' on buySellId.
tradeAmount or tradeQuantity negativeSchema-valid, but the receiver interprets the sign differently from the intention.
currencyType not an ISO 4217 codeSchema error on currencyType (code list ISOVAL).
Unknown field (additionalProperties = false)Schema error 'must NOT have additional properties' with the name of the extra field.

Difference from Release 2026 (001.04 → 001.05)

Frequently asked questions

Who sends message 10: the PUO or the investment administrator?

The investment administrator. The final manual of Release 2027 (12 October 2026) lays down that the BA role sends messages 10 and 14; a PUO does so only when it fulfils the BA role itself (issue #142).
