Introduction

Banks in Bosnia and Herzegovina are regulated at entity level. Therefore, we refactored the l10n_ba module and extracted bank data into a new module l10n_ba_fbih_bank_data. The new module is not a pure data module as it also contains validation rules.

Phase 1: Analysis and planning

We started by analyzing the existing l10n_ba module structure:

Phase 2: Creating new module

We created a new module l10n_ba_fbih_bank_data with dependency on l10n_ba:

Commit and push changes:

Phase 3: Database backup

Before deployment, we created a backup of the production database:

Phase 4: Migration script

We created a migration script with pre_init_hook for existing systems:

How pre_init_hook works:

Phase 5: Deployment and synchronization

Refreshing symlinks for odoo_addons:

Adjusting rsync script for modules inside packages:

Phase 6: Data validation

Checking BIC codes in CSV file:

Bank data format:

Phase 7: Successful migration

Migration verification - XML IDs now belong to new module:

Adding “Banke FBiH” menu:

Phase 8: Adding validation rules

Creating models for validation - res_bank.py and res_partner_bank.py:

Updating CSV file with bank_code column (BUG!):

Phase 9: Adding bank views

Creating XML view for bank display:

Updating manifest:

Commit and push changes:

Phase 10: Module upgrade on production

Running upgrade on production server:

Using colmena for deployment (lost memory - Claude wake up!):

Checking upgrade script:

Phase 11: Testing and verification

Verifying bank_code field:

Checking bank accounts:

Phase 12: Fixing reference issues

Finding lost bank references:

Updating bank accounts with correct references:

Verifying fixes:

Phase 13: Final deployment

Running final upgrade:

Checking module version:

Phase 14: Migration result

Successful migration - all records preserved:

Checking bank_code values:

Phase 15: Verification in Odoo interface

Checking module in Odoo:

List of installed modules:

Phase 16: Adding remaining banks

Upgrade with new banks:

Final list of banks with 3-digit codes:

Phase 17: Adding Razvojna banka FBiH

Updating CSV for Razvojna banka (code 195):

Complete list of banks with codes:

Final result

“Banke FBiH” menu with BIC codes display:

FBiH Banks List

Code	Bank
101	Privredna banka Sarajevo
102	Union banka
132	NLB Banka
134	ASA Banka
141	Bosna Bank International
154	Intesa Sanpaolo
161	Raiffeisen Bank
186	ZiraatBank
194	ProCredit Bank
195	Razvojna banka FBiH
199	Sparkasse Bank
306	Addiko bank
338	UniCredit Bank

Conclusion

This refactoring brings:

1. Better organization - bank data is in a separate module
2. Validation - 16-digit account number, 3-digit bank code
3. Entity separation - ready for l10n_ba_rs_bank_data and l10n_ba_bd_bank_data
4. Backward compatibility - migration preserves existing data
