"Unable to connect to the planning service" or "Error loading objects" messages display when opening Cognos TM1 Performance Modeler

Technote (troubleshooting)


When opening IBM® Cognos® TM1® Performance Modeler from the IBM Cognos TM1 Applications portal, Cognos TM1 Performance Modeler may issue an error.


Possible error messages:

Unable to connect to the planning service


Error loading objects


BAD: SplashHandler.ErrorLoadingObjectsMessage


This behavior is usually seen when opening Cognos TM1 Performance Modeler against an existing Cognos TM1 server that has been in use for some time and has been using older versions of Cognos TM1.

It is likely that the Cognos TM1 server contains corrupt objects, such as views with invalid dimension references.

Resolving the problem

Use Cognos TM1 10.1 Fix Pack 1 (or higher), where a fix was applied to Cognos TM1 Performance Modeler to display a more detailed dialog which reports the names of corrupt objects upon startup. In this version (and higher), Cognos TM1 Performance Modeler opens, but does not render the corrupt objects.

The error should then show the object with the problem - although it is not intuitive.

For example, instead of just the error, it will reference the corrupt object, as well, something like this:
BAD: SplashHandler.ErrorLoadingObjectsMessage
(Where Finance is a TM1 cube name)

Use Cognos TM1 Server Explorer to navigate to the Cognos TM1 server to locate and then either delete or fix the corrupt objects. This will likely entail opening all views in the mentioned cube to be sure that they all open correctly. If they do not, then delete the view and recreate it.
