In the Classic View of OAC and OTBI, it is possible to create one version of a dashboard that will only show reports and analysis that users have access to via their roles. This is not currently possible in Data Visualizer as the workbooks are secured at a higher level.
To reduce the number of workbooks needed to be built, it would be really useful to be able to secure individual visualizations on a canvas so that you can build one version and areas users dont have access to don't show at all rather than showing an error message or no data. For example, when building a cross functional workbook with both finance and HCM information, I want to only have to create 1 version of the workbook and hide sections rather than having to create and maintain multiple versions of the workbook.
