Functional question: ISR based on customer [l10n_ch_payment_slip]

Hi OCA,



We are trying to understand and use this module for one of our customer based in Geneva:
https://github.com/OCA/l10n-switzerland/tree/11.0/l10n_ch_payment_slip



We would like to get an ISR reference depending on the res.partner (so that each time the same customer pays, he can use the same ISR reference, even if he has 5 different invoices).

We found this documentation on the module about the ISR generation by Odoo:
123456000000500002018000149

The ISR is a 27 interger long string that is created upon VALIDATION of an invoice. It consists of the following parts:
(1) ISR-B Customer ID number (size: may vary) - this number identifies your company and is set in the bank account of your company’s partner as 'l10n_ch_isrb_id_number'.
To set this number, create a bank and bank account through Contacts > Configuration. There, you can assign the created bank, your company and an ISR-B number to the bankaccount.
(2) Partner reference filled by 0 on the left (size: 7) - this number is taken from the 'ref' field of a customer (partner).
(3) Invoice reference filled by 0 on the left (size: what is left) - this number can be found (for the most part) in the name of an invoice
(4) Control digit (size: 1)

But our tests are not OK. For example, we have one partner with internal reference 999 and another with internal reference 001.
For the 001 customer we generated 2 invoices, and it gave those 2 ISR:
01 12341 00000 00002 02000 06921
01 12341 00000 00002 02000 07941

For the 999 partner, we generated 1 invoice and the BVR generated is:
01 12341 00000 00002 02000 04980

We don't see the partner internal reference in the generated BVR.

What did we miss?

Thanks a lot for your help,
