How to dissolve/explode feature layer that is overlaping?

Hello there,

I have a question about one problem that I encountered with my data.

In atribute table I have one record, but there is overlaping line geometry.

Examples:

As you can see, under one line there is three lines. I dont know how they got there, but in my data this isn't a last error. So I wanted to know how to find that kind of errors in some kind of automation - maybe python.

Tried with 'Count Overlapping Features' analysis tool but it finds me records with overlapped geometry and different\unique attributes, so they are not like an errors. In this case those lines must be as they have been drawn.

Tried with 'Find Identical', but it's not working for my case as well. This does not finds records with overlapped geometry.

Thanks in advance 👌

Perhaps you have multipart features from the result of some merge operation previously. Try https://pro.arcgis.com/en/pro-app/3.0/tool-reference/data-management/multipart-to-singlepart.htm which might then allow the other tools to work as intended.

Thanks! You are right. ✌
Also tried Topology error validation. With that I can see self-overlapping features too.
