Add field source to Google Shopping module

[Alexenn]

Hello,

 

I am actually trying to import a data feed on Google Merchant, i'm using Google Shopping's Prestashop's module to do so.

Everything goes well until I have to match attributes that google need to make the feed with product's attributes on my website.

 

It seems that it needs one important information which is 'product's MPN', but there is no such source fields with product number in google merchant center..

 

So I was wondering if anyone knows how to add source fields into the dropdown menu ?

 

I tried to add itemprops (schema.org) on my product page, but it don't seems to analyze that, so i'm assuming google shopping has a link with the database, but I don't know where to add that.

 

Best regards
