S/4HANA is the fourth generation of the SAP Business Suite and stands for "SAP Business Suite 4 SAP HANA". It is ERP software that has been specially developed for the in-memory computing of SAP HANA. S/4HANA enables companies to process large amounts of data faster in real time and offers enhanced analysis functions and an optimised user experience. By integrating cloud technologies, companies can be more flexible and agile.

SFTP (or Secure File Transfer Protocol) is a means of transferring files securely. SFTP uses SSH (Secure Shell) and SSL (Secure Sockets Layer) to establish a secure tunnel to another system and transfer the data.

SGLN stands for Serialised Global Location Number. The SGLN is part of the GS1 standard system. The SGLN is a unique identifier and is used to specify the location of a product.

SHK-Mail is a closed mail system in which registered users can exchange electronic messages with each other securely. These messages are mostly EDI messages such as orders (ORDERS), order confirmations (ORDRSP), delivery notifications (DESADV) and invoices (INVOIC).

A Supplier Management Platform (SMP) is a software solution that helps companies to effectively manage and optimise their supplier relationships. By integrating EDI functionalities, an SMP enables seamless communication and collaboration with suppliers, resulting in more efficient transaction processing and improved compliance with EDI standards.

SOAP stands for Simple Object Access Protocol. SOAP is a message protocol that enables communication between decentralised elements of an application. It was developed as an intermediate language for applications with different programming languages. Through SOAP, these applications can communicate with each other over the Internet.

SSCC stands for Serial Shipping Container Code. An SSCC is an 18 digit number that is used to identify a logistic unit. A unit can be a lone item or a collection of items, e.g. a pallet or parcel. Having an SSCC is important as it uniquely identifies each unit, allowing it to be traced if necessary. An SSCC is essentially an English variant of an NVE number.

SSH, or Secure Shell, is a cryptographic network protocol used for secure connection to a remote server or computer over an unsecured network. It provides a secure channel for executing commands and transferring files, replacing insecure legacy protocols such as Telnet and FTP. SSH employs strong encryption to ensure confidentiality and integrity of data.

SSL (Secure Sockets Layer) is a security technology that encrypts the link between a web server and a browser, ensuring all data remains private. Initially developed by Netscape, SSL uses a dual key cryptographic system to encrypt data. While SSL has been succeeded by TLS (Transport Layer Security), the term SSL is often used to refer to both technologies.
