The PowerCenter Integration Service can process each row of an outbound IDoc according to the IDoc metadata and pass it to a downstream transformation. Enable row-level processing in the session properties. Row-level processing increases session performance.
If you disable row-level processing, the PowerCenter Integration Service buffers each IDoc before passing it to a downstream transformation. Buffering IDocs can decrease session performance.
If you enable row-level processing, the PowerCenter Integration Service does not validate outbound IDocs, even if outbound IDoc validation is enabled.
