SIVI message 1 (0001a): Capital (VB-PUO)

With message 1 the PUO reports the total pension capital at the start of the period: per pension scheme and per cohort (age cohort or reserve cohort). The fiduciary manager uses it as the starting point for the collective investment policy; the investment administrator uses it to reconcile independently. Optionally the message carries the intended allocation over investment portfolios (absolute or as a percentage).

Rules and consistency checks

The scheme total (pension.scheme.startAmount) and the cohort amounts (pension.cohort.startAmount) are delivered side by side. The standard does not require the cohorts to add up to the scheme total: according to the manual the receiver can, if desired, make a total calculation and check the reconciliation, depending on what the parties agree. SIVI's own sample message has 100,000 next to a cohort sum of 135,000.
Every cohort has a unique refKey and is described by startAge and endAge (integers since Release 2026) and a participation status from code list ADNDNS.
Reserve cohorts (solidarity reserve, risk-sharing reserve, compensation deposit) are flagged with reserveIndicator and typed with reserveType from code list AFDRES. Since the final Release 2027 reserveType is mandatory as soon as reserveIndicator is true (manual section 6.3), although the schema keeps both fields optional; reserveDescription is desired with code 99 (Other).
A cohort with value 0 may be sent with amount 0 or left out, also when it is a reserve; parties must be able to process both and record in their agreements what a missing cohort means. The standard has no field without a value (null) (manual section 6.3, issue #100).
financialInformation.reportingPeriod.startDate is the valuation date of the capital; the receiver checks that it connects to the previous period.
Amounts have at most two decimals (multipleOf 0.01); percentages at most twelve.

Pitfalls

A cohort that appears in message 2 (cashflow) but not in message 1: the receiver cannot place the mutation. Keep the cohort structure identical across messages 1, 2 and 3.
More than a few thousand cohorts or year cohorts make the message large: use the chunking protocol of Release 2026 instead of several separate messages.
The investment.portfolio block is optional and new since Release 2026; a receiver on an older release ignores it or rejects the message.

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.
Message function invalid (ADNFUN 01, 02, 09 or 54)Schema error on commonFunctional/0/function: value not allowed.
testMessage = true in productionThe message is accepted but not processed, or ignored as a test while it was production.
creationDateTime not a valid date-timeSchema error 'must match format date-time'.
puvCode unknown in code list AFDIDPSchema error 'must match exactly one schema in oneOf' on party/0/puvCode.
rsinNumber not 9 positionsSchema error on rsinNumber (length) at sender, receiver or pensionProvider.
party.sender: refKey or organizationName missingSchema error 'must have required property' on the sending party.
party.contact: emailWork or workPhoneNumber missingSchema error on the contact under the sender.
pension.scheme: refKey missing or pensionSchemeName longer than 60Schema error on the scheme.
startAmount not in two decimals (multipleOf 0.01)Schema error 'must be multiple of 0.01'.
reportingPeriod: endDate before startDateThe schema accepts the message; the receiver rejects it functionally or books the flows in the wrong period.
Cohort cardinality exceeded (minContains / maxContains)Schema error 'must contain at least 1 valid item' or 'must contain at most 99999 valid items' on pension.
participationStatus invalid (ADNDNS)Schema error 'must match exactly one schema in oneOf' on pension.cohort.participationStatus.
reserveType invalid (AFDRES)Schema error 'must match exactly one schema in oneOf' on reserveType.
reserveIndicator without reserveType, or reserveType 99 without reserveDescriptionUnder Release 2027 an error of the consistency check at reserveType. Under Release 2026 schema-valid, but the receiver cannot type the reserve and books it as an ordinary cohort; with reserveType 99 without a description it cannot tell which reserve is meant.
endAge smaller than startAge, or not an integerWith decimals a schema error 'must be integer'; with swapped bounds the schema accepts and the receiver rejects.
Cohort sum deviates from the scheme totalSchema-valid, but the fiduciary or investment administrator reports a reconciliation difference at scheme level.
Unknown field (additionalProperties = false)Schema error 'must NOT have additional properties' with the name of the extra field.
entityType does not match the fixed valueSchema error 'must be equal to constant' on entityType, often followed by 'must contain at least 1 valid item' on the parent array.
Chunking: chunkSequenceNumber or totalNumberOfChunks inconsistentThe receiver cannot close the series: sequence number higher than the total, duplicate sequence number or varying total within one currentChunkId.
Attachment: fileExtension not pdf, csv or txt, or fileName longer than 60Schema error on document.
Error discovered after acceptance: the correction protocolAn accepted and processed message turns out to be wrong in content (wrong amount, wrong cohort).
Schema draft mismatch: definitions versus $defs, draft 2019-09 versus 2020-12The validator reports 'can't resolve reference', MissingRefError or 'no schema with key or ref' when loading the schema, before the message is tested.

Frequently asked questions

What is the difference between message 1 (Capital) and message 2 (Cashflow)?

Message 1 is a position: the capital at the start of the period. Message 2 is a flow: the in- and outflows during the period. Together with message 4 (return) the chain closes the period: opening position + cashflow + return = closing position.

Who receives message 1: the fiduciary manager or the investment administrator?

Both, directly from the PUO. A principle of the standard is that an independent asset service provider receives the same information as the fiduciary manager, so that it can report and reconcile independently.

Is message 1 also used in the flexible premium arrangement?

Yes. The FPR messages 5 to 15 only cover the unitised flows. Collective flows such as risk premiums, reserve contributions and withdrawals from collective pools use the SPR messages 1 to 4 (manual section 4.1).

Are startAge and endAge in years or in months?

The schema prescribes integers and does not fix the unit; the official sample message uses months (300 and 780). Fix the unit in the chain agreements and keep it identical in all messages.
