Unique bank account numbers

It can be desirable to be able to rely on a bank account number identifying exactly one partner. This module allows you to enforce this, so that an account number is unique in the system.

There are some valid corner cases were it is valid to have multiple records for the same account number. For instance in a multicompany setup where the bank-account linked to one company, is a partner bank account for another company.

Because of these corner cases, the constraint is no longer implemented as a SQL unique index. This has the added advantage, that the module can be installed on databases where the bank-account numbers are not unique already.

To find records that are not unique, you could use the following SQL statement:

with res_partner_bank_sanitized as (
    select
        id, acc_number, coalesce(company_id, 0) as company_id,
        sanitized_acc_number
    from res_partner_bank
),
res_partner_bank_sanitized_grouped as (
    select
        array_agg(id) ids, sanitized_acc_number, count(*) kount,
        company_id
    from res_partner_bank_sanitized
    group by sanitized_acc_number, company_id
)
select * from res_partner_bank_sanitized_grouped where kount > 1;

Installation

The constraint is active for new and changed numbers, from the moment of installation.
