Within the SyWay Source-to-Pay transformation, supplier collaboration must support a broad range of processes:
As identified during workshops, standard solutions (S/4 + Ariba) do not fully cover the required collaboration scope, especially for:
Therefore, a custom SAP BTP Supplier Portal is introduced as the primary interaction channel
The scope is aligned with the “orange areas” from the functional scope diagram below
| Channel | Role | Usage Scope | Architecture Position |
|---|---|---|---|
| Ariba Sourcing | Sourcing platform | Used for all suppliers for RFx / sourcing events | Upstream (Pre-Procurement) |
| SyWay Supplier Portal (BTP) | Qualification platform | Used for all suppliers for qualification & onboarding | Lifecycle / Governance Layer |
| SyWay Supplier Portal (BTP) | Operational collaboration | Default platform for PO collaboration (non-BN suppliers) | Execution Layer (Default) |
| SAP Business Network (BN) | Strategic collaboration | Used for selected/high-volume suppliers for PO, ASN, invoicing | Execution Layer (Selective) |
| SAP Business Network for Logistics (BN4L) | Carrier collaboration | Used for all carriers globally | Logistics Layer |
| EDICOM | E-invoicing compliance | Used for country-specific e-invoicing regulations | Regulatory / Compliance Layer |
Enable operational collaboration between suppliers and S/4HANA
operational flexibility
supplier adoption
automation for high-volume suppliers
long-tail supplier accessibility
