Using Blacklines to Review Changes


Each time you generate XBRL documents, a new revision is stored in the document’s XBRL history. You can review changes that were made between two revisions of the XBRL documents by creating XBRL blacklines.

Generating XBRL

The XBRL history and blackline features are found on the XBRL tab of the Projects panel. The Projects panel appears only when a project is open. Make sure your filing document is part of your project.

  1. Open the Projects panel and select your project from the drop-down list if not already selected.

  2. Go to the XBRL tab and click Generate XBRL. You can choose to generate XBRL in the background.
