With the Historical Data Roll Forward feature, you can now leverage previous filings to roll forward XBRL-tagged historical data directly, simplifying the roll forward process.
To view historical data roll forward information, navigate to the XBRL/XML tab and enable Show XBRL. Click the gear icon, then choose Historical Data Roll Forward. From this menu, you can perform a historical data roll forward or view previous historical data roll forward processes.
Performing a historical data roll forward
On beginning the historical data roll forward process, you will be prompted with important information and reminders that will allow you to proceed smoothly.
On the second step, Set reporting period, you will set your current reporting period in order to find the appropriate filings to roll forward and ensure your XBRL fiscal dates are rolled forward.
On the Select filing step, you can choose a filing to use as the basis for your roll forward process.
You can then preview the number of changes that will be made when updating the selected filing and the sections where those changes will be made. If there are any issues related to your ability to implement changes, an alert will appear on this step.
You will then be prompted to enable track changes for the document. It is strongly recommended to enable track changes in all sheets so that you can review, accept, or revert changes. Proceeding without track changes will automatically accept all changes and may make it difficult to review the document for changes.
Once the roll forward is complete, you can review the full changes in detail. You can click a section title to open that section of the document to review the changes.
If track changes were enabled, you can now proceed to approve or reject tracked changes. For more information, see Track changes in Documents.
