No, I was awake for 32 hours, 5 of which I spent getting hypothermia in my
cold, empty house after driving 500 Km by starlight. The truck driver was
asleep in his vehicle at my gate when I arrived, with all of my stuff was
inside the vehicle. So sleep was the first priority, followed by coffee to
get me conscious, followed by a search of 8 rooms to find my carefully
labelled boxes of cables, followed by Internet connection. My office area
was full of boxes of clothes and dishes, also carefully labelled "Bedroom"
and "Kitchen" respectively.

I found this:
/* View: V_BESCHR_PROJEKTE */
CREATE VIEW V_BESCHR_PROJEKTE(
JOBNAME,
JOBNR,
NUMMER,
[snip])
AS
SELECT
PROJOBNAME,
PROJOBNR,
NUMMER,
[snip]
FROM T_Projekte;

Have you performed a SELECT * on this view to observe the cardinality of
the rows? I suspect you will find they are ordered by JOBNAME. If so,
create another view, with NUMMER as the first column, then see whether your
plan will be permitted then...

I wonder why you are joining to a view here.
