How to generate correct load statistics for Multi-table Insert (MTI), that is when a mapping uses a splitter operator to load multiple target tables?
When you have a splitter in a mapping, OWB will generate a Multi-table Insert (MTI) statement to load the targets in set-based mode. Since multiple targets are loaded in one statement, the insert count for each individual table cannot be obtained. Instead, a "combined" count for all the tables loaded in this statement is calculated. This is a limitation of the MTI statement, not OWB.
