# Create a simulation report to review changes

Importing a file generates a simulation report that shows what changes a package would make, without applying them. This helps you spot issues like missing dependencies, permission errors, invalid data, or externally modified packages. When the report is ready, the **Review changes** button appears next to the import job.

The report contains:

- *A summary section* that lists all errors and warnings. This includes missing items, insufficient permissions, and validation issues, such as invalid field values.
- *A package structure* that shows the package content as a tree, with status indicators such as *Modified* for updated items or *Skipped* for restricted items, for example system-owned settings.
- *Inline messages* that highlight item-level messages, such as a warning that a label will be overwritten.
- *Comparison views* that let you compare current and imported data side by side, either as field values or raw JSON.

> [!important]
> Because this process doesn't save items, some relation values might be marked as invalid.

To create a simulation report to review changes:

1. On the menu bar, do one of the following:
    - Click **Profile and settings** :mdiAccountCircle: > **Background processes** :mdiClockTimeFour:.
    - Click **Recent processes** :mdiAutorenew: and then click your import job.
2. Next to your import job, click **View report**.
3. To see the impact of an import, click **Review changes**.
4. In the **Review changes** window, review the report created for your import, then click one of the following:
    - To proceed with the import, click **Accept changes**, then in the **Confirm Changes** dialog, click **Accept changes**.
    - To cancel the import, **Reject changes**.

    > [!important]
    > After you approve or reject the import, the **Review changes** report is permanently deleted and cannot be recovered.
