Below error was a common error that can happen in Dynamics AX 2012 R3 EP, sometimes we hardly know what was missing or not configured properly:
- You cannot view data on this page because you are not a registered user in Microsoft Dynamics AX. Contact your Microsoft Dynamics AX administrator.
- No .NET Business Connector session could be found.
Here are some point that you might need to check
- Make sure the necessary inbound services was running
- Make sure BC connector been configured properly
Action that you might try:
- Re-create the AX user account (delete and import again the AX users)
- Delete and register/add again the EP website manually (System administration - Setup - Enterprise portal - Web site) [this one will always works for me for the 1st error point]
