Apportion Polygon - ERROR 002834: The geometry operation was cancelled.

Question

I am trying to use the Apportion Polygon tool to summarize the total square kilometers of crop land that falls in a series of travel time catchment area polygons.

My summary layer is a vectorized landcover crop mask. The target layer consists of travel time catchment area polygons (see screenshot - orange is input layer, blue is target layer). Both layers are in a file geodatabase, and I am only trying to summarize the AREA_GEO field into the target layer. After running for a couple of minutes, the tool failed with the following error messages:

ERROR 002834: The geometry operation was cancelled.
ERROR 002834: The geometry operation was cancelled.
Failed to execute (ApportionPolygon).

Alternative to this tool, I am open to using a combination of tools such as intersect and summarize within. My goal is to split the input polygons along the boundaries of the target polygons, and get the sum AREA_GEO field into the target polys.

Any help would be greatly appreciated!

To be sure, you should run

Multipart To Singlepart (Data Management)—ArcGIS Pro | Documentation

since some functions have issues with multipart geometry and do better with singlepart.

Then run a check geometry and repair if needed

Please check if there are any geometry issues, and fix it, if any.
