Edit: See the better version at the end of this answer.
Just use \renewcommand{\thechapter}{\Alph{chapter}}
after \backmatter
. But in my point of view, \backmatter
is of no use here.

Update with some improvements, replacing \backmatter
by an \appendix
command with slightly changed chapter header settings.
\appendix
switches to alpha counting by macro design.

Update redefining
\chapterlinesformat
Since KOMA-Script version 3.19 the command
\chapterlinesformat
can be redefined to change the layout of chapter titles that have no prefix line. Now it is possible to set a different entry for the page headings or to use the starred versions of the chapter title command. Chapter titles with more than one line are possible too.The following example uses
open=any
to show that it also works on left handed pages.Run twice (because
\Ifthispageodd
) to get
