Example 02: Payment Validation Framework

Overview​

The payment validation framework ensures data integrity and business rule compliance before processing remittances. This custom implementation goes beyond basic field validation to enforce complex business rules specific to EFT processing.

Implementation​

The validation framework operates at multiple levels:

Field-Level Validation​

Basic data type and format validation for individual fields like email addresses, amounts, and dates.

Business Rule Validation​

Complex rules involving multiple fields and external data:

  • Supplier must be active
  • Payment amount must match invoice totals
  • Email address required for EFT payments
  • Payment date within valid periods

Cross-System Validation​

Validation against SYSPRO master data:

  • Supplier existence
  • GL code validity
  • Currency validation
  • Tax code verification

Validation Pipeline​

The validation pipeline processes payments through multiple stages, collecting all errors before reporting to the user.

Error Reporting​

Comprehensive error reporting with:

  • Field-specific error messages
  • Suggested corrections
  • Batch validation summaries
  • Export to Excel for review

Performance Optimization​

Validation is optimized for large batches:

  • Parallel validation
  • Caching of master data
  • Early termination on critical errors

Benefits​

This validation framework has:

  • Reduced payment errors by 95%
  • Eliminated manual validation steps
  • Improved processing speed
  • Enhanced audit compliance

Summary​

The payment validation framework provides comprehensive data validation ensuring only valid payments are processed, significantly reducing errors and improving efficiency.
