This chapter is about model reference. Model Reference allows us to integrate, connect, and consume data from model entity sitting in any other environment within the same tenant.

For using the model reference function, a cross environment connection must be established and the environment from which the model entity is consumed.
Note
When it comes to the model reference (and the HANA connection), we don’t need a reader function on a top of these, because it’s a live connection.
Puling the data from another environment is just few clicks away from you in the Universal Model. Watch step-by-step tutorias on how to grab data from different environments.
In this video cross environment data flow is explained in opposite direction: writing the data from yours to another environment.
