Disallow the option "No Selection" (Solution field) on MOPZ start screen.

Anyone found any option without use customer code to hide the option to select systems without solution assignment in MOPZ start screen ?

After an upgrade from 700 to 71, we have a huge number of system that are not correctly assigned to a solution because data separation process don't assign it to a correct solution, i search it on security guide but don't found.

Thanks,

Luis
