I create a specific module wich modify module sale. he work when only sale module is installed. But when I add module CRM, my specific module don't work.

how to make it compatible?

This is my class ?

    'x_num_commande' : lambda obj, cr, uid, context: '/',
}

_columns = {
    'x_num_devis' : fields.char('Numéro Devis', size=15),
    'x_num_commande' : fields.char('Numéro de commande', size=15),
