Calculate the percentage of line features within a polygon in ArcGIS Pro

This is the first time I've had to do this particular task.

Calculating a polyline percentage that covers a specific feature, such as a waterbody? Ex: The lateral extends over the water, where I have to find what that percent is. For example, 55% is over the water, 45% is on the land.

I'm having a heck of a time learning how to do that in Pro 3.4. Have you had to do that using a geoprocessing tool, as I have close to a hundred of them?

The online and ESRI examples do not seem to help much when it has to use  Tabulate Intersection tool.. Any suggestions?

This is the error I get (at the bottom).

you have the zone and input class features switched I think.  The zones need to be polygons if the input features you want summarized are polylines.

You have pending Edits, possibly save them.

Your Zones and Classes are the wrong way around.

Zones =  water
Class = Lines

  • Using a higher dimension Input Class Features value than the Input Zone Features value is not supported.

    • If the Input Zone Features values are points, the Input Class Features values cannot be polygons or lines.
    • If the Input Zone Features values are lines, the Input Class Features values cannot be polygons.

If the Input Zone Features and the Input Class Features values are different dimensions (polygon zone with line class, polygon zone with point class, or line zone with point class), the output PERCENTAGE field records the percentage of the class intersecting the zone polygon.

LENGTH field is included in the output table when the Input Class Features values are lines. The LENGTH field contains the length of intersection between the Input Zone Features and the Input Class Features values.
