Rules and consistency checks

Two moments in the cycle: a preliminary NAV at T-4 (basis for the orders) and a final NAV at T+3 (basis for valuation and the payment information of message 14).
Per pool: unitsSummedValueAmount (mandatory), numberOfUnits and preliminaryUnitValueAmount; currencyType in ISO 4217. In SIVI's sample the pool value is the number of units times the unit value.
Release 2027 simplified the NAV structure; issue #136 (still open) proposes renaming preliminaryUnitValueAmount because the field also carries the final value. In the final Release 2027 the field still has that name.

Pitfalls

A final NAV sent with the same messageId as the preliminary one is rejected (duplicate messageId after acceptance); use a new messageId and refer with originalMessageId if desired.

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.
currencyType not an ISO 4217 codeSchema error on currencyType (code list ISOVAL).
Error discovered after acceptance: the correction protocolAn accepted and processed message turns out to be wrong in content (wrong amount, wrong cohort).

Frequently asked questions

How do I distinguish the preliminary from the final value?

By the moment (T-4 versus T+3) and by the reporting period; the schema has no separate status flag. Fix the convention in the chain agreements until SIVI has processed issue #136.

Change history
