How to add existing product variations to a new product display?
I am using Commerce Kickstart.
My client will be adding new product variations (SKU, price, title, VAT) in his separate database which he uses for billing customers in a physical shop.
The system I am setting up will be synchronising products between webstore and a database, mentioned before.
When new "products" (i.e. product variations) will be added, new Product (variations) will be created in webstore.
When he chooses to put this newly created (synchronised) products (variations) online, he should be able to create new product display (or existing one), then add existing (synchronised) variations to this display, to later equip them with photos and some other attributes.
I have tried to add another product reference field to the display with option to select among existing products, which somewhat works, but the problem is with displaying product with two "product reference" fields.
What I would like is to be able to add new variation as it exists in default settings with an option within that same reference field to add another one.
I hope I was clear enough about what my problem is.
