SOLVED : A table, Extended Data Type, Base Enum or class called TableName already exists. Import of Table aborted.

If during import of XPO file, we get the following error.

 A table, Extended Data Type, Base Enum or class called TableName already exists. Import of Table aborted.

This error is basically due to cache and ID mismatch problems for the related ojbects, 

Solution

Cache files - close the client, delete files .AUC files in cache directory:

* C:\Documents and Settings\[USERNAME]\Local Settings\Application Data for Win Xp or Server 2003,

* C:\Users\[USERNAME]\AppData\Local for Vista/Win7.

...and reopen the client, tyr import again.

Hope this helps

SOLVED : The AOS 'Name@2712' cannot be reached. Setup cannot continue.Verify that you entered the correct server information an that the AOS is running.

While trying to install the reporting services for AX 2012, i can across the following error on the setup.

The AOS 'Name@2712' cannot be reached. Setup cannot continue.Verify that you entered the correct server information an that the AOS is running.

This error is basically because the SetupSupport files pick the wrong/previous/deleted configuration for the Setup. The trick here is that along with the configuration what we fail to update is the Business Connected Proxy Account on the configuration, which normally points to the old server.

Solution :

Navigate to The Client Configuration from Administrative Tools, and change the Client Target to Local Client , and change the configuration to point to the correct AOS.

Navigate to Client Configuration Again, and change the Client Target to Business Connector, and point to the New AOS. :) 

Hope this helps :)
