Issues Importing iDoc into Definition Center
You are logged into the Definition Center and are trying to load an iDoc, but it just spins and fails to ever load successfully.
Resolution
Simply select a folder on the left hand side of the page under the section All Folders. Once you have selected a folder, you should now be able to select More Actions drop-down button > Import iDoc.
Once the import is complete, you should see a message notifying you.
