Overriding Pre Data Access, Post Data Access, and On-Fail exit points

In order to override thePre Data Access,Post Data Access, orOn-fail exit points of an entity in a subclass:

• specify the operation(s) of entity superclass in the subclass;
• enable thePre Data Access,Post Data Access, orOn-fail options as appropriate on the operations of the entity subclass.

For example, consider two classes, EntityClass and EntitySubClass with the subclass, EntitySubClass, inheriting the key and details of the superclass. The same operations would be defined in both classes; e.g.: insert, read, and modify. In both these classes these operations would have the following exit point options enabled:

• On Fail operation is enabled on operation insert;
• Post Data Access operation is enabled on operation read;
• Pre Data Access operation is enabled on operation modify.
