After a long time I came across the "Overview" documentation for IDM 4.0.2
again today and only then realized that this was the last version of the docs
that explains in detail how the engine actually works. Documentation for IDM
4.5 and 4.6 seem to have silently dropped that part.

So if you are interested in a much more detailed version of the "fishbone" than
what you see in Designer and iManager or like to read up on how a Synthetic Add
or the Merge Processor works, check out chapter 6 in
Also very helpful to follow traces and understand how/why the engine does what
it does!

Cheers, Lothar
