Not sure it would even be a good idea to try to get that back in. As you said it yourself...it was kinda inconsistent in the old.version.
Yeah, the 12c message definitely make more sens ....
Maybe you can try using inline prompts in these analysis? So it's during execution that users can set filter values (or dashboard prompts if users find these reports in a dashboard page).
I guess that if you even try to get the filters outside as saved filters the error will still be the same as the filter is also based on a subject area.
Yes it will for sure sinvce they're in a system folder tied to the SA
While the implementation was not consistent in 11g, the utility can't be denied. This limited answers access helps users share reports, they have been doing so in 11g with ease. These are not published reports, Power users would create reports and share particular information from their Areas with other departments, and instead of constantly having to share excel files, these users can login make slight modifications and get the data they need, without having access to the entire Subject Area.
In 12c this middle ground is completely gone, meaning power users will have to go back and redesign all the reports, maybe have to create dashboards/report prompts, as this is user generated content, IT will have no idea of impact.
Based on your comments, I get the feeling you also do not think there is a "setting" that can enable/disable this behaviour.
