ERROR
Attempts to split a line or polygon feature in ArcGIS Pro fail with the following error message:
Error:
Split failed. Geometry must intersect polylines and polygons in two or more places. Unable to obtain primary key value for origin object
Depending on the cause, use either one of the following solutions:
Set the split policy to Delete/Insert/Insert or remove the relationship class
To prevent conflicts when splitting a feature registered as versioned and contains a relationship class with the Update/Insert split policy, set the feature class split policy to Delete/Insert/Insert using the Set Feature Class Split Model (Data Management) tool in ArcGIS Pro.
If retaining the Update/Insert split policy is necessary for the feature class, an alternative is to remove the relationship class by following these steps:
As another alternative, if the relationship class and the Update/Insert split policy needs to be preserved, export the feature class as a new feature class instead. Refer to ArcGIS Pro: Export Features (Conversion) for steps.
Run the Repair Geometry tool to fix broken geometry
The Repair Geometry tool can be used to identify and repair broken geometry in a feature, which impacts tool usability. Refer to ArcGIS Pro: Repair Geometry (Data Management) for steps.
