I have aras innovator version 12 installed and I'm analyzing it using the InnovatorSample database.
The menu on which the dashboard is displayed cannot be found.
I would like to know if there are any additional settings.
Is there a particular dashboard you're looking for? Most dashboard displays are found by clicking the appropriate option in the Table of Contents. Their display is generally configured in the TOC View relationship of a given ItemType if you aren't seeing them.
