Hi,

We have a requirement to let the vendor add the vendor reference of the purchase order in the odoo portal (under my account, purchase order). When using the purchase reminder you can see that there is a possibility to let the vendor add delivery dates to the PO. 

In the same time I would like to give the opportunity to the vendor to add the vendor reference and write it back to the purchase order in the back end. 

We are on Odoo online (Saas) so I am not sure if it is possible by adding new inherited views or that it is only possible on odoo.sh or onpremise. 

I also tried to make the purchase order model available to the website builder form snippet. After this it will become available but it does not write back the vendor reference once you klik on the send button. 

Maybe someone on this forum has experience with such a request. All of your feedback is highly appreciated.
