Dual-instance SAP S/4HANA vendor invoice management architecture integrating OpenText VIM, IES, and IC4S for automated invoice capture and processing. Vendor invoices arrive via email SMTP, flow through OpenText Intelligent Capture and Invoice Capture modules, then route through the VIM Processing Engine to separate archive repositories and SAP instances. This design isolates HEU (S/4HANA 2021 with VIM 20.4 SP5) and HIL (S/4HANA 2023 with VIM 23.4 SP3) environments while maintaining centralized OCR and archive infrastructure. The architecture demonstrates best practices for multi-instance SAP deployments requiring independent vendor master data and invoice processing workflows.
