This set of Python functions helps you automate a number of map management and output (printing and exporting) workflows. You access this command by browsing to the folder in Arc Catalog where your map document is located and right-clicking the map document.

This option is not available for Arc Globe or Arc Scene documents.

You can immediately tell whether a layer on your map has a broken data link because it will have a red exclamation point next to its name in the table of contents, and the check box next to the layer will be unavailable.

A layer needs repairing if the data source it references has been moved, renamed, or deleted or is inaccessible for some other reason.
