I have the same layer in 2 different geodatabases and both layers have a different number of records.
I am looking for a way to compare both feature classes and find the records that are different between them to siolate them and add them to the one that has less records.
How can I do that?
Jose, Data Interoperability extension has a ChangeDetector transformer that will find unchanged, added and deleted features, or alternatively an UpdateDetector transofmer that will find unchanged added, deleted and updated records. UpdateDetector requires a shared primary key.
Also you Can try Using Select By Location—Help | ArcGIS Desktop using method Are identical to , then switch selection to get the different records.
Note: make the target layer in selection the layer that have records more than the other
