000435: Output must be a feature dataset because input is a feature dataset.


The Project tool can alter the spatial reference of a feature dataset. However, as the input is a feature dataset, the output must be a feature dataset. If the output name contains a dot (for example, fds.shp), the tool modifies the name to the second part (shp) only.


Specify a feature dataset as output. The output workspace should be a geodatabase.
