Error Duplicating Product Magento 2.1.2?

Question

After updating my Magento installation from 2.0.x to 2.1.2 I cannot duplicate products.

Suppose I try to duplicate a product with SKU number '10', duplication then yields the following error:

Product with SKU '10' is not linked to product with SKU '10-1'

I duplicate products by the following procedure:

• go to products/catalog
• choose a product in the list
• click on the arrow on the orange "Save" button and select "Save & Duplicate"

--> error

In the 2.0.x installation, I could duplicate products this way without any issue.

This a known bug. You can find the issue here: https://github.com/magento/magento2/issues/6764

According to the comment it seems like this pull request fixed the issue so I reckon it is fixed in develop branch: https://github.com/magento/magento2/pull/6957
