I created a movie which have an alpha channel. To prove the correct output i let show me every channel of the Movie using the commands ShowRed(), ShowGreen(), ShowBlue() and ShowAlpha(). Every channel look like it should so the resulting movie should have all information, also the alpha-channel. Add an info at the end of the script it shows an Output of RGB32-Movie

I created this avs to import the result in After Effects. Because AE does not understand avs-Files i created a pseudo AVI file with the avimaker from ffdshow package (It shows as colorspace RGB32). But when i import the AVI file in AE it does not show the alpha-channel. Also AE tell that the movie have only 16,7 Mio. colors. For Movies with alpha-channel AE display that those have above 16,7 Mio colors.

I don't know if this is here the right place to post this because avisynth does the job right as much as i understand. But where in the chain can be the problem? In AE itself?

I dont think After Effects tries to load the alpha channel from avis.
It probably only loads alpha from a certain set of files (TGA/PNG etc).
Anyway did you look up how (or if at all) alpha is interpreted from the file?

Also reimporting the fake avi file in AVS and using ShowAlpha - do you see the alpha?
