WooCommerce Invalid or duplicated Sku.

By the way – Great Product.

WooCommerce

I was able to configure my CSV and import all my variable products. With much confusion and conflicting information regarding the WooCommerce add-on. 18 CSV version and mutiple import configurations later I finally got there, with – Disable auto SKU generation? / Don’t check for duplicate SKUs.

When WP Import created the WooCommerce products the structure looks like this

Product – sku = 123
Variation Colour White – sku = 123
Variation Colour Grey – sku = 456
Variation Colour Black – sku = 789

ISSUE 1

When ever I save/update the product I get the following in the Variations panel:
Invalid or duplicated Sku.

Obviously the “Product” and “White Variation” have the same sku = 123

I have 3 options.
1. Ignore the warning
2. Manually open each product and delete the Product Data > Inventory > sku
3. Reconfigure my csv again – after getting so close – however any alterations to my import setting lead to other issues.

Please advise

ISSUE 2

I have added custom field to each variation and conditionally on simple products.
A select option. YES=1 or NO = 0 which I am using to flag specific products.

This custom field is registered in the product data, saved and can be loaded. All OK

The field was created with PHP and NOT ACF. As to my knowledge, ACF can’t add fields at the variation level.

When I do a WP All Export – The data for this custom field is not present
When I do a WP All Import – There is no mapping allowance for this custom field

Your feedback on how to solve these issue would be greatly appreciated.
