Once comparison is complete, the view differences screen is shown. Notice that the differences are categorized by type. This behavior can be changed by setting the 'group comparison results by type' option in the preferences dialog. Each type maintains a display of how many entries underneath it are selected for synchronization.
At the top of the display, the names of the two data sources being compared are shown on their respective left and right hand sides. The arrow points from the source to the target, and the target is always colored red. To switch the direction of the synchronization, simply click the arrow.
To view a list of the differences under any particular type, click the blue arrow on the left of the category. This shows the individual items
The check boxes next to each item can be ticked or un-ticked to specify whether that item is included in the synchronization. To select all or none of the items in a particular category, click on the green tick or red cross at the right hand side of the category. Clicking on the green tick or red cross of a top-level item (for example, 'Items only in Database: ...') will select or de-select all items in all categories within that group.
Clicking on the Synchronize button will take you to the next screen, the view action plan screen.
Clicking on the refresh button will re-load and re-compare the comparison.
Clicking on statistics will show the categorized totals of objects, and will look like the following:
The filter button is split into two parts. Clicking on the left hand part will bring up the filter dialog, discussed below. Clicking on the right hand part will control whether filtered items are hidden (the default) or whether they are shown. If they are shown, filtered items appear in gray. A category which only contains filtered items will also show in gray.
Clicking on the settings button brings up the comparison settings dialog, where comparison and generation options, as well as the comparison name, can be changed.
Clicking on the report button will generate a comparison report.
Clicking on the filter button brings up the filters dialog:
Here, we can change the mode in which filters apply, and add, edit and remove filters. The filtering system is exactly the same as is used for object browser filtering, with one minor difference: that the overall filter mode applies to the complete list of filters, rather than each individual one. Therefore, the overall filter mode drop down box is not shown when editing filters for use with a comparison scenario.
Having added filters to match extended properties and permissions, and set the mode to 'Include only matching objects' we return to the main display:
Notice that the filter icon is now gold, to signify active filters. Clicking on the right hand part of the filter button, and selecting 'Show filtered items' changes the display to the following:
Notice that the categories which contain no items are grayed, and they also say '0 selected' - showing that all items in those categories have been deselected. You can, if you wish, expand the items and select filtered items as you would normally.
Filters are saved with the comparison scenario, and will automatically be re-applied next time the comparison opens. Therefore, if there are specific objects that you wish to ignore every time the comparison is run, it is beneficial to set up a filter to automatically de-select those objects.
