Hello I'm Working on a Odoo V16 enterprise on SH.

Some facts:

- At this solution we are implementing the POS.

- We've created a Module Called "license plates" where we create cars with the info required like brand, chassis nº, type, and others. This license plates are LINKED to one client from my contacts.

- So... at POS I'm looking that after selecting the client it asks me for the license plate, not a free text but a combobox with a domain for the client selected

- We need then the pos sales linked to that license.

I was looking for modules but I'm not finding anything, do you think this is possible?

If there´s someone can help please let me know.

Best Regards
