It sounds like you are encountering an issue with the domain applied to your many2one field. In Odoo, a domain is a condition that is used to filter the records that are available for selection in a many2one field.

One possible solution to your issue might be to use an "and" operator in your domain to specify multiple conditions. For example:

Copy codelocation_id = fields.Many2one('crm.customer.location', string='Codigo', required=False, domain="[('location_type_id','=',location_type_id), ('partner_id','=',partner_id)]")

This will apply both the location_type_id and partner_id conditions to the many2one field, and will only show records that meet both criteria.

Another solution might be to use a computed field to filter the available records. A computed field is a field that is calculated based on the values of other fields, and can be used to dynamically update the domain of a many2one field.

For example:

Copy codefrom odoo import models, fields

class CustomModel(models.Model):
    _name = 'custom.model'

    location_type_id = fields.Many2one('crm.customer.location.type', string='Location Type')
    partner_id = fields.Many2one('res.partner', string='Partner')
    filtered_location_ids = fields.Many2one('crm.customer.location', string='Filtered Locations', compute='_compute_filtered_locations')

    @api.depends('location_type_id', 'partner_id')
    def _compute_filtered_locations(self):
        for record in self:
            domain = [('location_type_id', '=', record.location_type_id.id), ('partner_id', '=', record.partner_id

Hi William, have you ever found a solution for this issue? I've encountered similar behavior in v13.0
