Message-Level Validation
Message-level validation (MLV) is a script-based field-level validation against
Visa Acceptance Solutions
specifications. Your PTP uses amount-based test triggers to send transactions into a test environment and
the Visa Certification Management System for decryption. The test results are XML or
RESTful output,
Business Center
test transactions, and log prints. Visa Acceptance Solutions
validates the results with these activities:- Cross edit checks
- Data element validation
- Interchange compliance
- Data mapping validation
