I have created a custom product attribute named 'product_custom_label' on Magento ver. 2.1 which I been showing on product listing page. For updating its values I have provided the client with the CSV upload sheet like so:
sku | product_custom_label d-12 new arrival d-13 discounted
Updating the values is fine , but what I faced a problem is when I have to empty these values .
If I just remove the values from product_custom_label in the CSV, the attribute values are not emptied. I have already prepared a script to remove these values programatically but I wonder is not there a Magento way to remove/empty the values that we upload through csv?
The same problem is faced when I update the special price of the product.
So, is there any Magento way to empty out the value from a specific custom product attribute, or we just have to rely on mass edit functionality?
