Comparing Checked-Out Records with their
Originals
The Compare with Original command allows you to quickly compare a single checked-out record with its original version in the repository. It opens the same pop-up dialog as shown in the figure in Comparing Records, but instead of comparing different records the comparison is between the checked-out record and its original(s).

If the checked out record is the result of having previously merged multiple checked out records, then the checked out record is compared against all of the pre-merge originals.
The Compare with Original command is disabled for records that were checked out new.
To compare a checked out record with its original record(s):
...
1. In the Records pane, select the checked out record you want to compare to its original(s).
2. Right-click in the Records pane and choose Compare with Original from the context menu, or choose Records ® Compare with Original from the main menu.
3. MDM opens the Compare Records dialog.
4. Click the close button in the upper right corner of the dialog when you are done.
