The tool that created the result is missing a parameter description. Parameter usage information is important to users of your task so they better understand each parameter and its use.
Solution
For each parameter in your task, you need to enter a useful Description that explains the parameter. Browse to each task parameter page and enter a description.
More information
If the tool your task is based on started with a blank or empty parameter description, the information you enter into the Description box is saved back to the item description of the tool. If your tool had existing information in the item description, changes made within the Service Editor are not saved back to the tool.
