The EBA publishes detailed filing rules that govern how institutions submit XBRL reports. Understanding these rules is essential to avoid rejection. This guide explains the key requirements and how to comply with them.
Key Takeaways
- File naming convention is strictly enforced
- Module codes identify report types
- Reporting level distinguishes solo from consolidated
- Reference dates must be precisely formatted
- Version numbers enable resubmission tracking
Filing Rules Overview
EBA filing rules specify:
• File naming conventions
• XBRL and xBRL-CSV technical requirements
• Validation rule implementation
• Submission packaging
• Error handling procedures
Non-compliance leads to automatic rejection at the NCA portal.
File Naming Convention
EBA file names follow this pattern:
[LEI]_[ModuleCode]_[ReportingLevel]_[ReferenceDate]_[Version].xbrl
Example:
549300ABC123DEF456GH_COREP_CON_2025-03-31_001.xbrl
Every component must be exact—wrong separators, case, or formatting causes rejection.
Module Codes
Key module codes:
• COREP - Common Reporting
• FINREP - Financial Reporting
• AE - Asset Encumbrance
• LR - Leverage Ratio
• LCR - Liquidity Coverage Ratio
• NSFR - Net Stable Funding Ratio
• SBPRES - Resolution Planning
Use the exact code specified for your report type.
Reporting Levels
Reporting level codes: IND (individual/solo), CON (consolidated), SUBCOT (sub-consolidated other). Select the level matching your reporting obligation. Mismatched levels trigger validation errors. Some templates are only applicable at certain levels.
Resubmission Handling
To resubmit corrections:
1. Increment the version number (001 → 002)
2. Keep all other file name components identical
3. The new file replaces the previous version
4. Revalidate before resubmission
Document the reason for resubmission for audit trail purposes.
Checklist
- LEI code is correct and active
- Module code matches report content
- Reporting level is appropriate
- Reference date format is YYYY-MM-DD
- Version number follows sequence
- File extension is correct
- File name validates with naming checker
