Hello All,

I create a function for button(Send By SMS)  wizard action in Odoo10. In this function when i return value in the function following error shows on the screen. I also Define button action in sale order inherit file.  

The operation cannot be completed, probably due to the following:
- deletion: you may be trying to delete a record while other records still reference it
- creation/update: a mandatory field is not correctly set

[object with reference: partner_id - partner.id]     

So, What i return instead of code?

My Python and XML Code is Here:

Pythode Code:
