The saved views feature in Dynamics 365 Finance and Operations allows users to save personalizations into sets of views that they can toggle back and forth between.
They are excellent to improve user experience and efficiency, but they are not enabled by default, so they cannot be used if none enable them (see image below)
To enable this feature you must first access “Feature management” inside Workspace
Click on All > filter on “Saved Views” > Enable now
This will enable saved views (see image below)
