Before learning SAP Security, you need to understand the environment you are protecting.

In this first episode, we cover the foundations of SAP: what SAP is, how business processes connect across the enterprise, the major SAP functional areas, and the difference between an SAP system, landscape, and client. We also introduce SAP architecture and explain why understanding business processes is essential for anyone starting a career in SAP Security.

By the end of this episode, you’ll have the foundation needed to start exploring users, roles, authorizations, access, and risk in SAP.

How does SAP determine what a user can access and which activities they can perform?

In this episode, we explore the fundamentals of SAP Security, including user accounts, roles, authorizations, authorization objects, and authorization profiles. Learn how these components work together to control access in SAP ABAP systems.

Using practical examples from purchasing, we explain how SAP authorization checks determine whether a user can create purchase orders for a specific purchasing organization.

In this episode, you will learn:

• The purpose of SAP user accounts and client-specific access.
• How SAP roles organize business access and permissions.
• What authorization objects, fields, and field values do.
• The difference between roles and authorization profiles.
• How SAP authorization checks determine whether access is permitted.
• Why assigning a role alone does not guarantee appropriate access.

This episode is designed for beginners, aspiring SAP Security consultants, and IT professionals who want to understand the foundations of SAP access control.

Next episode: Explore the SAP Authorization Model and how access permissions are structured and evaluated.
