I have lots of tables and I know there are relationships between them because I can see some of them from Microsoft AX AOT. When I go to SQL server management studio and use database diagrams option I can add the tables I want but I cant see relationships? How can I see them?
If you're interested in table diagrams, and you have both AX 2012 and Visio installed, you can go to AX → Tools → Reverse engineer → Visio UML data model.
Or just right-click an AX project with tables → Add-Ins → Reverse engineer.
