Validations
Validations in SAP MDG are business-rule checks executed against master data attributes during change request processing to enforce data quality and compliance before data is activated or replicated. This topic covers how validation rules are modeled (typically via BRF+ or rule-based rule types configured against the MDG data model), how they fire during the create/change/single processing steps of a change request, how messages and severities influence workflow progression, and how consultants design, test, and troubleshoot these rules across on-premise and cloud deployments.
