Comparing Profiles for Mapping or Mapplet Objects

You can create a profile that analyzes two objects in a mapplet or mapping and compares the results of the column profiles for those objects.
Like profiles of single mapping or mapplet objects, profile comparisons run on all data columns and enable drill-down operations on the data that is staged for the data objects.
    1. Open a mapplet or mapping.
    2. Verify that the mapplet or mapping is valid.
    3. Press the CTRL key and click two objects in the editor.
    4. Right-click one of the objects and select Compare Profiles.
    5. Optionally, configure the profile comparison to match columns from one object to the other object.
    6. Optionally, match columns by clicking a column in one object and dragging it onto a column in the other object.
    7. Optionally, choose whether the profile analyzes all columns or matched columns only.
    8. Click OK.
