Yes, it is about acces right to select a channel for a particular user ( or even all user).
The goal is that I don t want users to see some channel from ChartPro.
But with these steps I can only hide object in scheme but in my case I would like to hide a defined device’s channel so that it can’t be selected in chartpro.
Rights are assigned on objects. Objects can have parents and children.
You could create a child object, set it to a channel, and assign necessary rights.
