User Management Issues

Hi Team,

I am   practicing on User & Role Management. some exercises done for general approach for user & Roles..

i don't see following options from Administration through HDB studio.

• How to copy from one user to another user?

• Suppose i create one user with respective Roles, same user roles need to copy to another user. ( mass user creation)

*Similar Mass Role creation

I believe this can achieve through procedures, anyone done that procedures?

thanks & Regards
