Duplicate Detection and De-Duplication

Home Prev Top Next

The following support for the handling of duplicate facts in XBRL instance documents is available:


In XBRL instance documents, a list of duplicate facts can be detected and listed in the Messages window. Run the menu command XBRL | Detect Duplicates or XBRL | Detect Duplicates on Server (high performance). See the description of the commands for more information.

When validating an XBRL instance document, you can specify that duplicate facts that affect calculations be ignored for the validation. The setting to enable this is available as an XBRL validation option.

When formulas are executed, tables generated, or Inline XBRL transformed, duplicates that exist can be ignored. This requirement can be specified in the XBRL Processing Options dialog.


Duplicates are determined on the basis of the rules set out in the Handling Duplicate Facts in XBRL and Inline XBRL 1.0 specification.
