EP AX2012: Data source metadata error > Unable to logon to Microsoft Dynamica AX

You will encounter this type of error from Enterprise portal, when you try to add AX data set to Dynamics AX user control.




Root cause: The root cause of this issue is “The WSDL Port and/or TCP/IP port number “is not matching with Enterprise portal WSDL / TCP IP port number.



Resolution:

Step1: Check the server configuration on EP server.

Step2: Map the same configuration on the local client.



Hope this will help… Best of luck.-- Mallik
