Features
You can determine a group of enrichment and validation checks for each payment order and payment item in enrichment and validation check sets. The system performs the checks during payment processing in a specified sequence and a specific processing mode. It determines an appropriate processing mode for payment orders and payment items based on the planned processing date. For more information, see Check Processing Date.
The system performs validation checks at different levels. For more information, see:
Note
The system performs cross item checks after the payment order check and payment item checks. It uses the same attributes for cross item checking as the attributes that you define for payment order checks.
Every check can detect normal and severe errors. If a check detects an error, the system logs the error, the enrichment and validation process continues, and the system runs all checks on all business objects. If a check detects a severe error, the severity indicator is additionally set.
