Merge Technique

The Merge documentation in Chapter 20 is almost not usagable. There is no clear info on the Merge object and how it is used in the process. The documenation on page 2 of chapter 20 has an object on the Master link that I can't identify. And the "Merge" object is in the middle suggesting that it is performing a merge process to the Out put data set, but when I try to connect it in either to the source object or the target I get the following message:

("40821) The destination stage does not support stream input links" This seems to be contrary to what the merge process is all aboutl

Is there any other documenation available? It is very important that I get this to work.
Thanks
Marilyn

The SERVER Merge stage takes no input links and outputs a single link. The input to this stage is two flat files that are sourced from within the stage itself.

The parallel Merge stage and the server Merge stage are two completely different beasts. The server Merge stage should probably be called FileJoin (because it joins two sequential files)
