Change Detector with Personal Geodatabase

It's hard to know what the issue might be without some hints as to what you might expect, but you might check to see if the coordinate precision differs between the formats? Try a CoordinateRounder applied to the same precision level for both inputs prior to the ChangeDetector and see if that helps.

Dave,

 

 

Thank you for the suggestion, I will try this out.  In the example that I was describing in the first post, we have a feature class with 4 features in it.  I deleted 1 feature and added a different one in its place.  So, the expected outcome from the ChangeDetector would be 1 added, 1 deleted, and 3 unchanged.  I get this result when comparing the SDE feature class with a shapefile, but comparing with the personal geodatabase does not give the same result.  When comparing with the personal geodatabase the result is 4 added and 4 deleted.  

 

 

I have tested comparing SHP/SHP, SDE/SDE, SDE/SHP (all give correct result).  Any time that a personal geodatabase is used however, the incorrect output from the ChangeDetector is given.  We would prefer not to have to create a shapefile from the personal geodatabase to run the ChangeDetector comparison if possible.  We would like to compare a personal geodatabase feature class with an existing SDE feature class.
