During the import process the Import Utility modifies the contents of the Smart Instrumentation database (for example, the target module or table). This is done by inserting, deleting and updating rows in the Smart Instrumentation database. It is therefore advisable to be able to coordinate between these rows before you start the import process.
This feature provides you with the means to coordinate between the rows to be inserted, deleted or updated during the import process. You do this by reviewing the source and target rows and selecting the appropriate rows that will be processed during the import process.
The Comparison tab only becomes active after the first time you have imported data and saved the selected link.
