odoo-addon-l10n-ch-pain-base 16.0.1.0.0.4

ISO 20022 base module for Switzerland

Switzerland - ISO 20022

This module doesn’t do anything by himself. It is the base module for 2 other modules:

• the module l10n_ch_pain_credit_transfer which adds support for the file format pain.001.001.03.ch.02 which is used for ISO 20022 credit transfers (SEPA or not SEPA),

• the module l10n_ch_pain_direct_debit which adds support for the file format pain.008.001.02.ch.01 which is used for ISO 20022 direct debits.

Known issues / Roadmap

This roadmap summarizes follow-up actions discussed in OCA/l10n-switzerland#754.

Short-term (merge-safe, keep architecture stable)

• Keep l10n_ch_pain_base close to legacy architecture for 16.0 migration.

• Avoid moving PAIN flavor declarations from feature modules into base only to satisfy tests.

• Keep base tests minimal and focused on base behavior; validate flavor-specific behavior in dedicated modules.

• Ensure CI is stable (including copier/CI profile alignment if conflicting modules require dedicated handling).

Mid-term refactor

• Review conditional logic in shared block generators that branches on pain_flavor and decide what should remain in base vs. move to extension modules.

• Revisit module split and responsibilities:

  • l10n_ch_pain_base: common/shared generation logic.

  • l10n_ch_pain_credit_transfer: credit-transfer specific behavior.

  • l10n_ch_pain_direct_debit: confirm if still needed in current architecture.

• Reduce duplicated Swiss-specific logic where practical while preserving backward compatibility.

Swiss standard update (time-bound)

• Prepare support for Swiss credit transfer pain.001.001.09.ch.03.

• Plan deprecation path for pain.001.001.03.ch.02 (announced acceptance window ends around Nov 2026).

• Validate generated XML with official SIX validators and real bank acceptance tests.

• Address format differences required by new standards, especially postal address handling and structured remittance/QRR compatibility.

Implementation checklist

• [x] Keep migration PR scope limited and merge 16.0 base migration.

• [ ] Open a dedicated refactor PR for shared vs module-specific PAIN logic.

• [ ] Open a dedicated standards PR for pain.001.001.09.ch.03 support.

• [ ] Track rollout status in this roadmap and link follow-up PRs/issues.
