When you add or change a file reference in a mapping, and the path cannot be resolved, MapForce displays a warning message. This way, MapForce diminishes the chance for broken path references to happen. Nevertheless, broken path references may still occur in cases such as:
•You use relative paths, and then move the mapping file to a new directory without moving the schema and instance files.
•You use absolute paths to files in the same directory as the mapping file, and then move the directory to another location.
When this happens, MapForce highlights the component in red, for example:
Broken path reference
The solution in this case is to double-click the component header and update any broken path references in the Component Settings dialog box (see also Changing the Component Settings ).
