Using KOMA-script for my dissertation, does make me a bit confuse. Reading its manual is a bit daunting since I am a new user of KOMA-Script although I am a self-proclaimed average LaTeX user. Here I will give a guide to create fancy header. I will not explain a lot, just directly put my LaTeX source so that you can get them directly to create a fancy header. Here's the source:
I put all of my main full source so that you can imagine how to fit KOMA-Script into your source. The part of the source which come from KOMA-Script listed below:
Preparation
Header Definition
Display "Abstract" Title
The result is the document which has page number as the footer in every beginning of the chapter and the fancy header with chapter - section - page number and line for the next pages.
I believe that you love to read the manual, so if you want to know the meaning of the commands above, have a look at KOMA-Script manual. :)
