Handling Deprecated Concepts

On the XBRL tab, click Advanced, then Taxonomy Migration, and choose Find Deprecated Concepts to Replace.

Deprecated concepts are displayed in the Notifications panel.

Now you must update any deprecated concepts as part of migrating to the 20XX taxonomy.

Choose a concept, then double-click it in the Notifications panel.

Deprecated concepts appear in the left-hand Location Finder panel. You will need to choose each concept and manually migrate it through the migration path. If no migration path is found, you will need to search for a replacement concept.

When you click on a concept, the XBRL Detail Tagging window appears. There will be a D before the concept, indicating it is Deprecated. Click on the D.

The XBRL Migration Paths box appears, making suggestions for replacement concepts.

Choose the most accurate replacement for your concept, then click the green check mark on the new concept to apply it.

The XBRL Migration Paths box has other information that may be useful to your migration, such as:

  • Mapping type and description

  • Deprecated concept.

  • Replacement (new) concepts.

  • Click to accept the replacement concept or view concept details.

  • Official taxonomy notes about why the concept was deprecated.

In the case of deprecated and unapplied concepts in the XBRL Outline, you will want to update them. These concepts will appear under XBRL Outline Locations. Click on the deprecated concept you wish to update.

The concept will appear within the right-hand XBRL Outline panel. It will be grayed out to indicate that it is deprecated. Right-click the concept and choose Replace.

You will be prompted to either manually search for a replacement concept, or have the application make recommendations by clicking the Migration Path button (recommended).

A Migration Path dialog box will appear, giving you options of concepts to update to.

NOTE: After you’ve updated your deprecated items, make sure you Share your XBRL changes.

You should also update your Project Properties so that it reflects that you are now in the 20XX taxonomy. Go to the right-hand Projects pane and click the Project Properties button.
