SAP S/4HANA is an Online Transaction Processing (OLTP) system. This means that SAP S/4HANA focuses on completing the daily work of the business as quickly and efficiently as possible. People only need access to the specific functions that they perform in their daily work.
The figure illustrates a standard sales process comprising various steps performed by different users, each of which aligns with a specific application or transaction. To execute these tasks within the system, users must possess the necessary authorizations associated with these applications/transactions and the organizational units they represent, including Company Code and Sales Organization. These authorizations are essential for users assigned to specific organizational units where these business processes are established.
When establishing security measures for your SAP S/4HANA system, applications, transactions, and field values are paramount considerations. Specific users are limited to certain transaction codes, and field values cover activity fields (such as creation and modification) as well as critical business data like sales organization, business area, and plant. Most companies have a few of these fields that are integral to their entire security implementation.
