openSUSE IS a rpm based distro
BUT they do things very VERY differently that redhat dose
Most of the time i would NOT use rpm to install software
suse uses "zypper" just like redhat uses "yum"
IF!!!!! and this is a BIG IF!!!
if this unknown rpm IS !!! for the current opensuse 13.2
it should be in a software repo
-- install the repo
if not and this is something like LibreOffice that is self contained and OS independent
rpm or zypper can be used
Warning:
DO!!! you have ALL!!! and every prerequisite for this unknown rpm installed ????
if not it will not work
