Filtering events in the browser can be done either by Event Filter and/or by RTSM View.

the use case you describe seems like you need filter by event's attribute (category=hidden) so you need Event Filter.

Unfortunately, Event Filters are optional. You can create Workspace with event browser, select event filter, and then save it. I think other users who will access the workspace will see the event filter pre-selected.

Event Browser can be accessed with "Clear View Filter" but this is only relevant for RTSM Views (meaning user has to select view), but if your events' related CIs are the same (regular and "hidden" events) then this option is not relevant.

the last option I can suggest is assign events. You can create role in which these users can only see events assigned to user yes/no. Using automatic assignment rules you can assign regular and hidden events to different groups. so then user without permission to see events not assigned to user, will not see those events.

The only thing I dont know if it will work is assignment to Group while the role restrictions is "assigned to user". but it worth trying...

Let me know if you need more info.

Hello Marta,

You could achieve this via permissions in the user role.

You can define which event category a user is allowed for unassigned events.

Unfortunately to hide one, you will need to explicitely select all other categories (and make sure you add new categories when they come up).

Best regards,

Thank you so much for the responses Asaf and Tobias.

We were exploring this way, assigning events with the marked categories. But we have to do some work standardising the categories. 

Best Regards
