Duplicated products when import

Hi!

I am using your WP All Import Pro to import and updating my products.

– I have a .txt file with arround 100.000 products from my supplier
– I am using Custom Field where i put in the EAN number to grab data/images from IceCat
– I am also using the update function to only update price and stock quantity
– Unique Identifier: {eannummer[1]}

I successfully imported all products with Custom Field (name: icecat_sku & Value: {eannummer[1]}) where it graps the title, description, categories, images etc. from IceCat just fine. (took me almost 2 weeks to import all this because of data from icecat)

But lets say, if i get 13 new products from my supplier in the .txt file (so it is now 100.013 products) How do I only import the 13 new products and not import the 100.000 already existing products in WooCommerce? Can I use the Function Editor with some code?

I have tried to figure this out for a long time and i don’t do codes so maybe you can help fustrating me to solve this?

BTW: I love your products with all the features – only problem is when i get new products in the .txt file i can’t figure out how to solve. The same way how to delete the products if they are not present in the .txt file anymore (lets take that later)

Hope you can help me!

Thank you
