Error adding field to sales order model.

Question

Good day everyone
We have this custom code to add a field to sales order object and shows error.  Any idea what could be wrong?    Version 15
source:
from odoo import models, fields, api,exceptions

class SaleOrder2Sap(models.Model):

_inherit = 'sale.order'

pedido = fields.Char(string="No Pedido")

Error:
psycopg2.errors.UndefinedColumn: [1] column sale_order.pedido does not exist

Thanks in advance

thanks both for your help, I was upgrading the module from list view in apps.  then I clicked the module to open details and upgraded from de command button that did the trick.
