SAP Integration

Built around real SAP processes.

Architecture

Where ESS Hub sits in an SAP landscape.

ESS Hub runs outside SAP as the supplier collaboration layer. It exchanges business documents with SAP through the integration layer the landscape already has, so supplier processes stay connected to SAP without a portal inside the ERP.

ESS Hub does not replace SAP purchasing, logistics or invoice verification. It makes them reachable for suppliers.Outside SAP · connected to SAP processes

Business process flows

Supplier collaboration, mapped to SAP processes.

Each supplier interaction in ESS Hub corresponds to a business document on the SAP side. The direction changes; the process stays connected.

Connectivity by system

SAP ECC. SAP S/4HANA. One supplier experience.

The supplier-facing process stays the same whether the backend is ECC or S/4HANA. What changes is the integration method behind ESS Hub, chosen per landscape.

ESS Hub is developed by EDI & SAP Solutions SRL. SAP ECC and SAP S/4HANA are the primary integration expertise; the architecture connects to other ERP systems through EDI, API, SFTP, files and integration middleware.

IDoc & business documents

Business process, EDI message, SAP representation.

The relationship between what the supplier does, the message that carries it and the object it becomes in SAP.

Seeburger / middleware

Works with the middleware you already run.

Many SAP landscapes already have an EDI or integration platform. ESS Hub is designed to sit next to it, not to replace it. ESS has worked with Seeburger BIS and other EDI platforms for years, and that interoperability is built into how ESS Hub is deployed.

Master data

Supplier processes run on enterprise master data.

The documents ESS Hub exchanges refer to objects the enterprise owns. How that data reaches ESS Hub is defined per landscape; the objects are the same ones SAP uses.

Suppliers

The supplier record every order, shipment, quality notification and invoice is addressed to.

Vendor

Materials

Part numbers as they appear in the call-off, the ASN and the invoice.

Material

Plants

Receiving plants on demands, shipments and quality notifications.

Plant

Purchasing organizations

The organizational context of the purchasing documents.

Purchasing

Purchase orders · scheduling agreements

The purchasing documents the supplier process refers to.

Documents

Delivery data

Shipments, handling units and delivery documents against the demand.

Integration visibility

See the message, not just the status.

Integration problems are easier to solve when the business user can see the message behind the document. ESS Hub keeps the EDI representation next to the business object and validates structure before a supplier goes live.

  • Message structure validation

    Sample DESADV or INVOIC messages checked for UNB, UNH, BGM and UNZ segments and balanced segment counts during onboarding.

  • Message view per document

    The EDI message behind an ASN or an invoice can be opened from the document itself.

  • Test parameters per supplier

    Endpoint, protocol, test GLN and partner ID for the EDI test phase.

  • Document status

    Packed, dispatched, acknowledged; posted, paid: the same status on both sides.

  • Monitoring views

    Logistics and financial monitoring on the enterprise side.

  • Audit trail

    Enterprise administrators have an audit trail of actions in the portal.

Open ERP architecture

Deep SAP expertise. Open ERP architecture.

SAP ECC and SAP S/4HANA remain the primary target. The same document model and the same integration layer connect ESS Hub to other ERP environments through standard interfaces.

SAP expertise is our heritage. ERP independence is part of the architecture.

EDI & SAP Solutions

Integration first. The portal came later.

EDI & SAP Solutions SRL was founded in 2013 in Brașov, Romania. The company designs, builds and supports integration landscapes for manufacturing and automotive companies: SAP and EDI integration, B2B connectivity, Seeburger BIS, IDoc interfaces, EDIFACT, VDA and ANSI X12 messaging, API and SFTP / MFT exchange.

ESS Hub is the supplier-facing layer designed for those landscapes, built by the same team that runs the SAP and EDI interfaces behind them. That is why this page talks about IDocs and DESADVs, not about features.
