Rules and consistency checks

Per investment pool: buySellId (buy or sell), tradeValueAmount (cash effect), unitsSummedValueAmount, preliminaryUnitValueAmount and numberOfUnits.
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.
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.

Frequently asked questions

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

That depends on who keeps the unit administration. In a self-administering fund that is the PUO; where the investment administrator keeps the units, the BA sends. SIVI has been asked to clarify the manual on this point (issue #142).
