Answer 1

You need to update few things in code.

Specify relation attribute in fields.function, you have defined that many2one as field type but it's related to which model ?.

And other things is that company_id.currency_id it gives you an browsable object not an id.

So try following,

def dame_usuario(self, cr, uid, ids, fieldname, arg, context=None):
    res = {}
    for obj in self.browse(cr, uid, ids, context=context):
        result[obj.id] = False
        user = self.pool.get('res.users').browse(cr, uid, uid, context=context)
        if user and user.sucursal_u:
            result[obj.id] = user.sucursal_u.id
    return res

    _columns = {            
                'name': fields.char("Name", required=True),
                'act_user_suc': fields.function(dame_usuario,
                    type='many2one', readonly = True, relation='sucursales'),
                }
