This Document defines and offers an example of a working testcase of the MULTITABLE Insert.  It also documents the restrictions of this feature.

MTI Definition:

It is common within many systems that, external data sources have to be segregated based on logical attributes for insertion into different target objects. It is also frequent in data warehouse environments to fan out the same source data into several target objects. Multitable inserts provide a new SQL statement for these kinds of transformations, where data can either end up in several or exactly one target, depending on the business transformation rules.
