A full path was used as the input parameter for this tool. The tool requires a relative path to the dataset.
Input dataset names for this parameter use paths relative to the input workspace. For example, if you use a SQL Server database connection as the workspace input, the relative path would be something like <database>.<user>.<dataset>.
For more information on relative paths, see Paths_explained:_Absolute,_relative,_UNC,_and_URL.
