I created two schemas: Customer (XDM Individual Profile) with an attribute called Booking ID (Non-Person Identity Name Space) and Booking (using a Custom Class also named Booking) with the Booking ID (Non-Person Identity Name Space) as the primary identity. I also established a one-to-one relationship between the Customer (Source Schema) and the Booking (Destination Schema) based on Booking ID. Created Datasets and enabled profiles. After ingesting the data into the datasets, I was able to view the profile, but no Destination Schema Attributes were visible.
My reference was Define a Relationship Between Two Schemas Using the Schema Editor | Adobe Experience Platform
So far, I have been able to create an audience using the Destination Schema Attributes, but I need to utilize them in Personalization.
