Install
This is the repository archive. It installs, but the folder name will carry the branch suffix and updates will not flow.
Install straight from GitHub with WP-CLI:
wp plugin install https://github.com/mihaimangu/wp-custom-variation-sku/archive/refs/heads/main.zipNo built-in updater. New versions won't appear under Dashboard → Updates. Install new releases yourself, or let Git Updater track the repository.
For woocommerce production variations, adds the ability to set a custom field "external_sku" for each variation.
In my case, this was required in order to link to an external SKU, in my stock keeping software (Oblio).
