Split Tool clears attribute values

[BrianBulla]

Hi,

We are noticing that when we select a line feature and then use the Split tool from the standard editing tools, that a specific attribute is getting set to <Null>.  Has anyone ever experienced this?  Any explanation as to what might be causing this??  It's just one specific attribute in both halves of the split line feature.

Thanks,

Sounds like you defined a domain for that field and didn't set the split policy to "Duplicate":

Thanks Johannes!  So does ArcMap not enforce the Split Policy?  We are only seeing this behaviour happen in ArcGIS Pro.

I don't have ArcMap installed anymore, can't test. But it should honor split policy according to A quick tour of attribute domains—ArcMap | Documentation (arcgis.com)

If you don't see that behavior, that might be a question for the ArcMap community.
