What are variations?
Van der Meer has products with multiple variations. A bag of dog food in with different contents (e.g. 500 gram, 1 kilogram and 2,5 kilogram). It would be nice to have those variations imported as a variable product in WooCommerce, instead of having a lot of separate simple products.
Recognition of variations
Luckily, Van der Meer has a nice logic to recognise parent products and its variations by using following numbers in their XML feed.
Automatic import of variable products
The Van der Meer WooCommerce plugin imports variable products automatically if a following number is present in the XML feed of Van der Meer.
