Digital Sign With SAP

How Digital Signatures Work in SAP S/4HANA & ECC

Introduction 

Digital signatures rely on cryptography, but their real value comes from how seamlessly they integrate into business processes. In SAP ECC and S/4HANA, this integration must be robust, scalable, and user-friendly. 

The Technical Foundation of Digital Signatures 

• Hashing algorithms 

• Public/private key encryption 

• Certificate authorities 

• Time stamping 

These components ensure authenticity and integrity. 

Digital Signatures in SAP ECC & S/4HANA 

SAP environments differ: 

• ECC: Traditional, transaction-heavy 

• S/4HANA: Real-time, Fiori-based, cloud-ready 

SimpSIGN supports both seamlessly. 

SimpSIGN Architecture 

• SAP-triggered signature requests 

• Server-based signing engine 

• PKI certificate integration 

• Secure document storage 

Manual vs Automatic Signing 

• Manual: User confirms approval 

• Automatic: System signs based on rules 

SimpSIGN supports both. 

Benefits Across SAP Landscapes 

• Zero workflow disruption 

• High performance 

• Enterprise scalability 

• Cloud and RISE compatibility 

Conclusion 

Digital signatures in SAP are not just about security—they are about process intelligence and trust. SimpSIGN ensures ECC and S/4HANA systems are future-ready.
