The Analyze button in the Service Editor identifies errors and other potential issues that you need to address before you can publish your geoprocessing service.
When analyzing your service, you'll notice three types of messages in the Prepare window. You can right-click each message to get a quick suggestion on how you can address that specific issue. This will also give you access to a help topic with more information, such as additional repair options. The item in bold in the Description column is the default approach for addressing each issue.
If you need more time to correct the issues in your analysis, close the Service Editor and save your service configuration as a draft. You can continue your work by opening the draft in a future session in ArcGIS for Desktop. See Opening a draft service in ArcGIS for Desktop for full instructions.
