# Transient mapping

Use the Transient Mapping to specify a or field of the entity class that is not persistent.

To create a version mapping:

1. In the Persistence Outline view, select the field to map. The Persistence Properties view (for attributes) displays the properties for the selected.

2. In the Map As field, select Transient.

Eclipse adds the following annotation to the field:

    @Transient
