Multihoming of SuSe 10.1

I have two physical NICs on my SuSe 10.1 box.

I am running two separate subnet VLANs and want this box to see each of
them, so I have configured one card to one address say: 10.20.30.40/24
and it works fine ( I use Yast). The moment I configure the other NIC
with an IP say: 10.100.200.10/24, my first card looses it's ip and
second NIC gets the right one assigned. For this also, I use Yast here
too.

All I need to do is multihoming (without routing). Also, what's the
purpose of enable Ip Forwarding check box? I have tried both
ways...with or without the check marks.

Why am I unable to assign both the NICs, their IP's?

Individually, both NICs are working fine.

Don't use NetworkManager. It's primitive and doesn't understand
a plethora of networking scenarios. Try using the alternative
ifup method instead (Yast asks you which style to use). You should
be able to configure both interfaces. I do this all of the time.

You only need ip forwarding if you want to forward packets across
the interfaces.
