Can anyone tell me how to fix an error after running the topology rule in ArcGIS? I tried to subtract and create a new layer, but a failed warning appears every time.

What error are you getting? – Timothy Michael Mar 24 '11 at 13:35
Because there are so many topology rules you could have set up, it would also be helpful to explain (possibly a graphic), of which topology rule, what type of feature classes participate in the rule, as well as the error. – RyanDalton Mar 24 '11 at 16:31

You need to use the topology toolbar enter image description here

Then use the error inspector to locate the topology error in order to fix the correction

If the error you are getting is "Failed to create new feature" and you are using topology in ArcGIS 10, install Service Pack 1 to fix it.
