Using Cache Data Property to Improve Business Component Performance
To cache on the AOM the content of a business component for subsequent use in the same user session, the property Cache Data property should be set to TRUE for the business component.
Setting Cache Data to TRUE is appropriate for semi-static data that may be subject to repetitive queries, but that is unlikely to change during the user session.
For some business components, Cache Data is set to TRUE by default. This is done, for example, for the PickList Generic and Internal Product business components. (See Using Properties to Improve Picklist Performance.)
Cache Data should be FALSE for business components representing transactional data that may change within a user session.
