Thanks for your help. It's great!

What I recognized is when I put this on layer for better placement of
the header it doesn't work.
Here is an example:

\def\Schulaufgabekopf%
  {\bf \tfa
      \setupTABLE[option=stretch]
      \setupTABLE[frame=off]
      \setupTABLE[column][1][width=0.7\textwidth]
      \setupTABLE[column][2][width=0.3\textwidth]

\setupTABLE[row][2,3,4][background=color,backgroundcolor=gray,frame=off]
      \setupTABLE[row][5][height=1cm]
      \bTABLE
      \bTR \bTD \strut \eTD \bTD \strut \eTD \eTR
      \bTR \bTD \AAnr \eTD \bTD Date: \eTD \eTR
      \bTR \bTD  Name:    \eTD \bTD Points: \hfill of \nofPoints \eTD\eTR
      \bTR \bTD  Form: \Klnr   \eTD \bTD Mark: \eTD \eTR
      \bTR \bTD [nc=3, align=low] \tfxx   Unterschrift eines
Erziehungsberechtigten: \thinrule \eTD \eTR
      \eTABLE}

\definelayer[kopf][width=\paperwidth, height=\paperheight]

%Klassenarbeiten Kopf
\def\AAnr{2. Schulaufgabe Englisch 2006/2007}
\def\Klnr{10 \hfill}
%\definelogo[SAK] [top][left][command=\Schulaufgabekopf]
%\placelogos[SAK]


\setlayer[kopf][x=1.9cm, y=1cm]{\Schulaufgabekopf}
\setupbackgrounds[page][background=kopf]
\starttext

% Lets set 10 problems with different points
\dorecurse{10}
   {\pkt[\recurselevel] \input tufte \endgraf}

\stoptext

What's going wrong?
