I do not see data, even if I have the role

(Translated from another language)
I do not see data even if I have the role necessary for reading the data. What is the reason?

The role is either not enabled itself or it is not enabled in the model. Both his demonstrated by displaying the role in italics in the class or query detail, where you do not see the data.
Another possibility might be that the role is not activated in your profile. Click on the user icon in the upper right corner, select the option with your name and roll down to the list of roles on the page that will open. Such an role that is not activated in your profile is not checked there. This is usual with strong roles, that should not be assigned to users once they logon, but users should rather activate them deliberately.
