After I install
openSUSE-Leap-15.1-ARM-XFCE-raspberrypi3.aarch64-2019.05.17-Snapshot1.18.
raw .xz to a RasPi I get a IP via DHCP during the first boot.
Then I configure a fix IP via YaST. But this fix IP is configured as
secondary IP. Even if I remove the interface configuration and renew it
with the fix IP - after the YaST config runs throught, there are a
interface with a primary addess from DHCP and a additional secondary IP
from the fixed config.
Where i can change this tricky behavior?

Please show some confirmation:

With this config it is not possible to connect to the I-Net. When I
delete .181 the connection is possible but after a while dhcp is rising
again.

How do you configure it? Looks like you added a connection instead of editing

the existing one.
No, I configure the existing interface.
From my POV it looks like an added IP for an existing interface. But
there is only one address configured for this interface. When look in YaST.
If I do an:
# ip addr del 192.168.250.181/25 dev eth0
The main addr of eth0 is removed, even as the secondary IP and the
address 192.168.250.185 is set as the main addr of eth0.
After a while somewhat reconfigure the network to the old state where
the DHCP addr is set :-\

It seems that I found the trick.

Ootb the NetworkManager is active. But if you enter the YaST lan part
you did not get an hint as in openSUSE for x86_64. So two configs fight
each other.

I remove the NetworkManager (zypper rm -u Networkmanager) and now it get
only my configured address without an additional IP from DHCP.
