SAP systems are at the heart of many large organizations, handling sensitive business operations such as finance, HR, and supply chain management. Given this critical role, authorization management becomes essential to ensure that users can only access data and functions they are explicitly permitted to use. Improper implementation of these authorizations not only introduces security vulnerabilities but also exposes the system to internal misuse and SAP-ABAP-based crimes.
This article explores SAP’s authorization model, how it integrates with ABAP applications, and the potential risks and misuses that can occur due to weak or abused authorization concepts.
In SAP, authorizations determine which actions users can perform in the system. They are part of a structured authorization concept that includes:
These elements work together to enforce access control at a granular level, often embedded within ABAP applications to protect data and functionality.
An authorization object groups up to 10 authorization fields. It checks whether a user is allowed to perform a certain activity (e.g., read, write, delete) on a particular object (e.g., customer data, documents).
Example:
F_BKPF_BUK (Accounting Document Authorization)BUKRS), Activity (ACTVT)ABAP developers must explicitly code authorization checks using the statement:
AUTHORITY-CHECK OBJECT 'F_BKPF_BUK'
ID 'BUKRS' FIELD lv_bukrs
ID 'ACTVT' FIELD '03'.
If the check fails, users should be restricted from proceeding.
SAP roles contain authorization objects and are assigned to users via the Profile Generator (transaction PFCG). A single role can encapsulate dozens of permissions needed to perform specific job functions.
One of the most common ABAP-related security issues is neglecting to implement AUTHORITY-CHECK statements in custom programs. This can allow unauthorized users to run sensitive transactions or view restricted data.
Risk: Unauthorized access to financial or HR records.
Granting users roles that exceed their job requirements—often due to lazy role management—violates the principle of least privilege.
Risk: Insider threats or unintentional misuse leading to data breaches.
Some malicious or negligent developers may write ABAP code that skips or overrides security checks, especially in custom reports or batch jobs.
Risk: Potential fraud, such as unauthorized invoice generation or data manipulation.
Authorizations tied to technical users or background jobs are often overlooked, leading to potential misuse or unauthorized data extraction via RFCs or APIs.
Risk: Data exfiltration, especially when linked with third-party systems.

However, improper use or deliberate circumvention in ABAP custom code can open the door to fraud, data leaks, or unauthorized actions—often referred to as SAP-ABAP crimes in risk audits. Understanding and correctly implementing SAP authorization concepts is not only best practice—it's essential for compliance, trust, and business continuity.
