CUA Distribution model for Roles and Profiles to Redist

Hi Expert,

Currently we are having CUA system installed on Solman 7.1 box.

And we need to change the CUA parameter for role and profile, to redist mode.

But unfortunately when in edit mode the Redist is grey, so we cant select it.

Is there anything else we can do to make this happen ?

Cheers,

Raff
