Using XBRL Blacklines

next generation

Use XBRL Blacklines to compare changes between two generations of XBRL documents.

Creating an XBRL Blackline

To compare one XBRL generation with another, create an XBRL blackline. XBRL blacklines are created in a separate file that are not stored in Wdesk.

To create an XBRL blackline:

  1. Open the XBRL Generation History panel on the right.

  5. Click Create XBRL Blackline. Wdesk generates the blackline and downloads the file.

Understanding Blackline Changes

XBRL blackline shows what is new in green and what is changed in red, similar to track changes. However, blacklines changes do not indicate the user who made the changes.
