QRT validation involves both technical XBRL checks and EIOPA business validation rules. This guide explains the validation layers, common errors, and how to produce compliant QRT submissions.
Key Takeaways
- Validation has technical and business layers
- BV rules check cross-template consistency
- TV rules check XBRL technical compliance
- Both must pass for successful submission
- Pre-validation saves time
Validation Layers
QRT validation includes:
1. XBRL technical validation
2. Taxonomy conformance
3. EIOPA business rules (BV/TV)
4. Cross-template consistency
All layers must pass for successful filing.
Technical Validation
Technical validation (TV) checks:
• XBRL syntax conformance
• Schema validation
• Linkbase validity
• Context consistency
• Unit definitions
Business Validation
Business validation (BV) checks:
• Cross-template balances
• Logical consistency
• Required data presence
• Value range checks
• Calculation relationships
Common Errors
Watch for: BV cross-template mismatches, missing required cells, calculation differences exceeding tolerance, incorrect period types, and dimension member combinations not in hypercube.
Best Practices
For successful validation:
• Validate each template individually first
• Then validate the full submission
• Review all warnings, not just errors
• Document any intentional deviations
• Keep validation logs for audit
