Industry Challenge

The client's legacy flat file payment outputs did not meet strict SEPA and CBPR+ standards required to provide ISO 20022 files to its primary clearing bank, J.P. Morgan. Without timely remediation, the company faced potential payment rejections, operational delays, and downstream supply chain disruption under an urgent regulatory deadline, without disrupting core ERP systems.

Our Approach and Solution

Configuration-Driven Translation

A dynamic configuration layer maintained the client's reference and master data, enabling consistent mapping between legacy flat file formats and ISO 20022 structures.

Validation Checks

On upload, the parsing engine ran syntactic checks and J.P. Morgan-specific semantic validation, catching errors before reaching the bank.

Automated Conversion

Clean records were transformed into the mandated pain.001.001.09 ISO XML format, supporting high straight-through processing with J.P. Morgan from day one.

Exception Management & Reconciliation

Failed records were extracted into a bad file with precise error descriptions, backed by dashboard summarizing totals processed, passed, and failed.
