Edit Portlet Form Design-Time Considerations

In addition to standard form properties, you can control the transaction boundary for edit portlets. You can choose to process each action (that is, insert, update, or delete) on the form separately (Transaction Disabled), or you can process all of the actions at once (Portlet Only Transaction). Choose the latter if processing each action separately would cause data integrity issues. Transaction processing for edit portlets is identical to that for subforms.
