The Import Export PowerTool does not maintain its own dedicated import or export log inside Microsoft Dynamics 365 Business Central. This is a completely free app from Insight Works for Business Central. The main record of what changed is the Business Central change log, provided you do not disable it during the operation. Your source text file also serves as a practical record of exactly what you imported.
The change log is the primary audit trail
When the change log is active for the tables you are working with, Business Central records inserts, modifications, and deletions made through the tool just as it would for changes made in the standard interface. This gives you a built in audit trail of what data changed, when, and by whom. Because the tool writes directly to the tables using your permissions, those changes flow through the same change log mechanism as any other activity. If auditability matters for a particular load, confirm that change logging is enabled for the relevant tables before you run it.
Why the disable change log option affects logging
The tool offers an option to temporarily disable the change log during an operation. This exists because large imports and bulk updates can generate very high volumes of change log entries, which can slow the operation and add clutter. The trade off is that when you disable the change log, the affected changes are not recorded there. In other words, data can be imported or updated without leaving a change log record. This is useful for performance on big loads, but it means you lose that portion of the audit trail, so use it deliberately.
Your source file as a record
Beyond the change log, the text file you imported is itself a reliable record of what was loaded, since the tool imports exactly what the file contains. Keeping your import files, organized by date or task, gives you a clear reference for what was applied to the system even when you choose to disable the change log for speed. Many teams retain these files as part of their data migration documentation.
Managing change log volume
If you keep the change log enabled and accumulate a large number of entries over time, Business Central includes a retention policy feature that you can use to manage and age out change log entries in a controlled way. This is the recommended approach for keeping the change log useful without letting it grow without limit. The tool can technically remove change log entries when protected table access is enabled, but deleting audit records directly is not advisable, so rely on the retention policy instead.
Related Tools
Import Export PowerTool is the Insight Works app for fast import, export, update, and delete operations in Business Central. It relies on the native change log for an audit trail and offers an option to disable that log when speed is the priority.
There is no separate logging report built into the tool, so plan your audit approach around the change log and your retained source files. Keep change logging enabled when you need a record of changes, use the retention policy to manage volume, and reserve the disable change log option for high volume loads where you accept the reduced audit trail.
