Supplier Portal
The structured channel. Suppliers confirm dates and quantities per PO line — accept, modify or split a delivery — directly, with no interpretation needed.
PO confirmation, orchestrated
Vendor Date Hub (VDH)
Every change, in context. VDH keeps the purchase-order confirmation cycle continuously aligned with SAP — across channels, systems and users.
The Operational Problem
Different suppliers respond in different ways.
Confirmations arrive by email, as PDF attachments, in Excel files or as free text — in any language. The buyer absorbs the variance:
- Understand each response and find the purchase order it refers to.
- Match it line by line against what was ordered.
- Validate changes in dates and quantities.
- Type the result into SAP by hand — hours of manual work every day.
Why It Matters
PO confirmation is an operational dependency.
Supplier confirmations keep delivery and customer commitment dates realistic. When they fall behind, the effect travels beyond procurement.
- Production: plans built on confirmed, current delivery dates.
- Sales: customer promises that hold — and customer trust.
- Buyers: most confirmations handled automatically; people review only the exceptions.
- Audit: every confirmation traceable from source to SAP.
How It Works
Context first. Then the decision.
From the supplier’s answer to a verified confirmation in SAP — with people involved only where their judgment is needed.
Read POs from SAP
Open purchase orders — header, items and schedule lines — are the baseline for every response.
Understand any response
VDH identifies the supplier, rebuilds the context and turns the response into structured facts.
Match & validate
Each line is resolved and checked deterministically against SAP, business rules and tolerances.
Human review, only for exceptions
What matches is confirmed automatically. Buyers approve, correct or reject only what needs them.
Controlled write to SAP
VDH writes the confirmation, reads it back to verify, and reconciles any divergence.
Complete traceability
Source · evidence · PO version · applied rule · decision · resulting action
AI interprets. VDH validates deterministically. SAP governs the transaction.
Two Channels. One Confirmation State.
Supplier Portal, Intelligent Email and Buyer Control Tower
Suppliers answer the way that suits them. Both channels feed the same confirmation state — versioned, traceable and written to SAP under control.
Intelligent Email
The unstructured channel. Emails and PDFs in free text and any language are routed to VDH: a first AI agent extracts the content, a second puts it in context, and VDH applies deterministic validation and decision rules.
Buyer Control Tower
The buyer’s workspace for what needs attention: exceptions, approvals, KPIs, alerts, history and reconciliation — plus the rules and tolerances that drive automation.
The Architecture
Built on SAP BTP. Alongside S/4HANA, without modifying the core.
VDH complements SAP and Ariba — no forced replacement, no mandatory new workspace.
Interfaces
SAPUI5 Supplier Portal for external users and SAPUI5 Buyer Control Tower for internal teams.
VDH core on SAP BTP
CAP services on Cloud Foundry for PO reading, confirmations, validation and rules, controlled SAP writes, reconciliation, audit and history.
Integration with SAP
OData and SOAP to read and write S/4HANA through Destination and Cloud Connector, with event-driven synchronization where Business Events are available.
Security & governance
Identity and roles, HTTPS/TLS, audit trails, monitoring with alerting and controlled retries, and GDPR-aligned retention policies.
No VDH channel, AI or user writes directly to SAP. Every change is governed by the VDH core.

Demo: from supplier email to SAP
Two real cases, start to finish: one confirmation that matches exactly and syncs to SAP with zero clicks, and one split delivery outside tolerance that the buyer approves with a single click.
