Persistency Tab Page 

Definition

Use this tab page to define how a business object is stored.

Use

In the Persistency tab page, you can select if the business object is to be persisted locally or in an external system. You can also see the table names created for the business object, including information on namespace, name, and description.

Structure

Table created as part of the modeling of business objects, 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 be changed by the application developer (for example, if there is a table name collision that cannot be resolved automatically by the CAF Designer). For a business object with local persistence, at least one table is created.

To use remote persistency, you should map the business object service operation to an external operation on the Datasource tab page.
