Hello,
Yes, it’s possible. You just have to setup the import settings first, over:
– Tools & Reports > Product Import Costs Tool > Key to import from
If you have been using this Cost of Goods plugin probably you won’t need to change any settings.
After that you can access:
– Tools > Import Costs
And click on “Import”.
If the import doesn’t work for the variations, probably you’ll need to run the import again having the “Key to import from” set to _wc_cog_cost_variable
And remembering that it’s always a good idea to make a backup in situations like this 🙂
Let me know if it helps 😉
