Hi Vikas,
Thank you for answering. In my case I have one environment, which I will share it with multi-users. By using multi-tenant I can give each user a space, where he can use the App without influencing the other users. But each user (e.g userA) need to have a additional featuers or screens, that other users don't need it, so I need to add the featuers to userA and don't allow others User to use it.
OutSystems Roles dose't do the job, since each tenant has his own Roles
I hope I could give you more details.
Regards.
