@sam.mckay Do you have an example or showcasevideo with a datamodel that is the same or similar with the following example:
A (online) store is selling jeans, shoes and t-shirts. A customer can buy all those products in 1 order so there will be 3 orderlines.
In the showcases I have found there is always 1 order with 1 product so always 1 orderline.
I hope you can help me.
