Hello, I have a question regarding sample data and schemas which we have created during tutorial. During schema creation we have created custom data type with system identifiers. The loyalty field group was not part of "root" node. But now i am in section about batch data ingestion where this custom data type contains also Loyalty node - Second printscreen. I can't find the step in the tutorial which would do this move. Is it even possible? How can i get loyalty node under my custom data type no...
