Message reference

pain.001.001.08 Reference: Generate and Validate

pain.001.001.08 — the last pre-2019 version. Element structure, version notes, and version migration.

1 min read Last reviewed

pain.001.001.08 closes the first generation of the message. Its structures sit closest to version 9 while retaining the older element names, which occasionally makes it a low-friction stop in staged migrations.

What to know about this version#

  • A pragmatic halfway house when moving a v03-era integration towards CBPR+ alignment in two steps.
  • Pain001 validates it against the official XSD like every other version.

Element structure (all versions share this skeleton)#

  • <GrpHdr> Group Header — message id, creation timestamp, NbOfTxs, CtrlSum, initiating party. Pain001 recomputes the control totals from validated records.
  • <PmtInf> Payment Information — debtor, debtor account and agent, requested execution date, payment method, charge bearer; one block can carry many transactions.
  • <CdtTrfTxInf> Credit Transfer Transaction — amount and currency, creditor, creditor account and agent, remittance information, end-to-end reference.

Generate and inspect#

pain001 init pain.001.001.08 -o work/         # scaffold a starter CSV
pain001 inspect pain.001.001.08               # list required + optional fields
pain001 -t pain.001.001.08 -d payments.csv -o out/ --dry-run

Records can be reshaped between supported versions. The mapper renames and defaults fields to match the target version; elements the target does not model are not carried over, so re-validate after migrating:

from pain001.migration import VersionMapper
rows = VersionMapper().migrate_rows(
    rows, "pain.001.001.08", "pain.001.001.09"
)
