inconsistentDuplicateNumericFactInInlineXbrlDocument

Introduction

Use this article when the validation report contains the error inconsistentDuplicateNumericFactInInlineXbrlDocument. This error indicates that the same concept has been tagged multiple times within the report, but the reported fact values are not identical.

Summary

After following these steps, you can identify the duplicate concept, determine the cause of the inconsistency, and correct the tagging or fact values.

Overview

In iXBRL, the same concept may appear multiple times within a report. This is allowed, provided that all occurrences represent the same fact and therefore contain the same fact value.

When the validation engine detects that the same concept has been reported multiple times with different fact values, it generates the inconsistentDuplicateNumericFactInInlineXbrlDocument error.

Steps

1. Open the validation report.
2. Locate the concept mentioned in the error message.

3. Copy the concept name.

   Remove the taxonomy prefix before searching.

   For example:

   • ifrs-full:Revenue → Revenue
4. Open the inline viewer.
5. Search for the concept.
6. Open one of the search results.

The inline viewer will show all occurrences of the selected concept in the report.

7. Compare the reported fact values.
8. Determine why the values differ.

Common causes

Cause 1: Incorrect sign configuration

In some cases, the reported value is identical, but one occurrence is reported as positive and another as negative.

For example:

This is typically caused by incorrect sign configuration.

Review the Concept is negative property and verify that the sign handling is configured correctly.

Cause 2: Different facts using the same concept

In other cases, the concept has been assigned to two facts that represent different information.

For example:

In this situation, one of the facts is likely tagged with the wrong concept.

Review both occurrences and determine whether they represent the same economic meaning. If not, one of the values should be tagged with a different concept.

Expected Result

All occurrences of the concept use the same fact value, or the facts have been assigned to the correct concepts. The validation error no longer appears after generating a new iXBRL package.

Remarks

• The same concept may appear multiple times in a report, provided that all occurrences represent the same fact.
• The inline viewer is the easiest way to identify and compare duplicate facts.
• After making changes, regenerate the iXBRL package and review the validation report again.
