If you specify collection of time-ordered information in the import definition, you can accumulate the update information for the target system in the time-ordered information table during import processing. By collecting update information in chronological order, you can retrieve a history of updates as an update ledger or analyze the frequency of update processing. In addition to update information, you can also collect information such as the import dates, import times, and update types. For details about the available types of time-ordered information, see 4.3.7 Creating a time-ordered information table.

The following figure shows the concept of collecting time-ordered information.
