Hello,
I have 8+ years of experience in Odoo. I have successfully completed a wide variety of odoo modules and customization project for small to medium scale businesses. I have expertise in odoo technical and functional aspect and can deliver the best results for your requirements. please have a look at my profile and reviews that show my expertise in odoo.
I checked attached pdf, i got all the requirements of generating feed live, include those custom fields ( starting with "x_") , it'll be compatible with both community and enterprise versions and also noted the mappings of fields,
I have done one similar feed export in a project very recently, I can demonstrate that example.
looking forward to hearing back from you soon,
Regards,
Zahir
