The “XML message for Credit Transfer Initiation – Implementation Guidelines” (ABBL, Version 3.2, March 2026) defines the Luxembourg implementation rules for the ISO 20022 pain.001.001.09 Customer Credit Transfer Initiation message. It sets out the structure, mandatory and optional data elements, formatting rules and validation constraints for both SEPA and Generic Credit Transfers submitted to Luxembourg banks. The document aligns SEPA requirements with EPC standards and incorporates additional regulatory frameworks for cross-border and high-value payments. It provides practical guidance and examples to ensure consistent implementation, operational efficiency and regulatory compliance across the Luxembourg banking sector.
