Error Code SCHEMA

Schema Mismatch - MT to MX Structural Breakdown

See how mapping issues and structural differences between MT and MX formats create schema mismatches and payment rejects.

Why this rejection happened

The transformed payload failed because a field, mandatory element, or ordering rule from the source MT message did not map cleanly to the target MX schema.

How to fix it

Map the incoming MT fields to their exact MX path and verify mandatory elements, cardinality, and XML namespace compliance. Focus on pacs.008 or pacs.009 requirements before releasing the transformed message.

Common trigger points

MT103 to pacs.008 mismatch
MT202 to pacs.009 mismatch
XML field ordering failure
