Persistency Tab Page 

Definition

A type of index used to define how an entity service is stored.

Use

In the Persistency tab page, you can select if the entity service is to be persisted locally. You can also see the table names created for the entity service, including information on namespace, name, and description.

Structure

Tables created as part of modeling entity services, follow a naming convention, which has the prefix XAP_ and is followed by a generated key. Table names cannot be longer than 18 characters and may conditionally be changed by application developers. In an entity service with local persistence, at least one table is created.

When mapping to an external service, you have to use remote persistency.
