Hi,

did you find the solution to that?

thanks and regards.

This is an old thread, but I figured posting solution here to help out new comers.

This is supposed to work on Odoo 11 and 12, not tested on older versions.

When import your "product.template", specify "id" for each one of them as you see fit.

Based on the "id" just created, to generate a .po file matching the desired translated language.
Remember to add headers for .po file in order to let Odoo properly load it.  Either directly load the .po file or within custom module put it in "i18n" folder and name it something like zh_TW.po (Traditional Chinese)

Assuming the "id" for this particular product is "product.product_template_test1", we are translating the "name" field.

#. module: stock
#: model:product.template,name:product.product_template_test1
msgid "ABC-TEST"
msgstr "ABC-測試"
