I created a new project in which the team only wants one individual to have write access. What would be the best way to accomplish this goal?
CA Harvest SCM all versions and platforms.
For the user to which you want to grant read and write permissions, you would grant execute permissions on all the necessary processes to accomplish this, such as Check Out for Update/Concurrent Update, Check In, Delete Version, etc.
For the users to which you do NOT want to grant these permissions, only grant them execute permission on a Check Out for Browse process.
