PFE Circulee is a comprehensive toll transaction data flow architecture integrating multiple source systems (AUTRES_CIRCULEES, REFERENTIEL_PEAGE, TRANS) into a central processing hub. Data flows through PFE_CIRCULEE from inbound sources including toll references, vehicle information, and transaction records, then distributes to downstream systems: SAP for accounting entries and payment status, PA/SERES for e-invoicing and reporting, and ADVU for validation. The architecture implements bidirectional acknowledgment flows (ACK_CRTRANS, ACK_CRMENS, ACK_GARJU, ACK_TRAITEMENT, ACK_COMPTABLE) ensuring data integrity and processing confirmation across all integration points. This pattern demonstrates a hub-and-spoke data integration model critical for toll collection operators managing complex multi-source transaction pipelines.
