In the Metadata Manager, you can run and manage comparison reports to identify differences between two metadata snapshots. A snapshot is a "picture" of the metadata from a specific environment taken at a specific time. A snapshot may include all metadata types, or only selected metadata types. You can run a full snapshot comparison report for all metadata in the environment, or a selected snapshot comparison report for selected metadata. The Snapshot Compare reports compare the Active snapshot with the default Primary snapshot.

You can also run a comparison report between metadata in the Eagle's Gold snapshot and your Primary snapshot. The Eagle Gold snapshot contains Eagle's core metadata for the current release.

Run the Full Snapshot Compare Report

The Full Snapshot Compare report has the following options:

  • Simple Item Compare. Compares item differences of all metadata types, and includes any differences in the Item Name, Item ID, and item attributes. The snapshot compare is performed by the Item ID. The Item ID Component attribute describes what makes the Item ID unique for each type.

  • Simple Map Compare. Compares datamap differences of all metadata types, and includes any differences in the datamap owner, datamap attributes, and datamap source type and target type.

To run the Full Snapshot Compare report for all metadata types:

  1. From any Metadata Manager window, click Snapshot and select Comparison Reporting.

You can access the Item Detail window only for items that are present in the Active snapshot.
