Ulrich, thank you for the bug report.  However, it is not something
we can use, because you haven't given any real example that we can
reproduce.  Can you give us something like:

    a set of create table statements +
    a set of insert statements +
    a select that demonstrates the problem .

Without knowing the contents of the bezug, artikel and adressen
tables, we can't tell what might be going on.

We look forward to more information, so that we can identify and
fix this problem.

Thank you,

Tim
