How does SAP VIM work?

VIM moves each invoice through capture, validation, exception handling, and posting. Invoices arrive by email, electronic data interchange (EDI), IDoc, supplier portal upload, or scanned paper. A capture product extracts the header and line-item data, and VIM validates that data against SAP master records, purchase orders, and goods receipts.

Each business rule has a responsible role assigned to it, and each role sees a defined set of resolution actions, so when an invoice fails a rule the system already knows who should look at it and what they are allowed to do. An invoice that passes every rule, including duplicate detection, vendor master checks, and two- or three-way purchase order matching, posts to SAP without anyone touching it. An invoice that fails a rule becomes an exception and routes to the responsible person or team based on configurable rules tied to amount, vendor, cost center, or organizational unit. Depending on configuration, the invoice is parked or posted and payment-blocked while exceptions are worked, then released once every exception is resolved and every approval is complete. Approvers can act from SAP Fiori or a mobile device. Every step records a timestamp, the person who acted, and any comments, and at the end of the process VIM can render the complete history into a PDF attached to the invoice record, so the audit trail builds as the invoice moves rather than as a separate documentation task.
