What is SAP t-codes?

SAP transaction codes (t-codes) are short alphanumeric strings that represent specific entry points within an SAP system. They allow users to navigate through different SAP modules and perform tasks such as creating sales orders, generating reports, or managing inventory. Each transaction code triggers a sequence of predefined steps and processes, enabling users to access and manipulate data stored in the SAP system effectively.

What is the program behind a t-code?

The technical entity behind a transaction is usually an SAP program that runs the transaction’s actual code. The code is generally written in ABAP (SAP proprietary programming language).

What is the Authorization check process for a particular t-code?

In order to provide comprehensive support in SOD (Segregation Of Duties), SAP allows extensive roles and authorizations administration to control data access and use of t-codes. There are multiple solutions to tie authorizations check for a particular transaction(s), usually combined via authorizations role, which represents a role in the organization (for example – buyer, finance controller, salesperson, etc.).

The complexity and criticality of SAP systems makes it necessary that transaction codes perform as expected and meet business requirements. Testing t-codes helps identify potential issues, such as functional errors, performance bottlenecks, or security vulnerabilities, before they impact daily operations.

To enhance the efficiency of the testing process and ensure thorough coverage, it is vital to include these important steps:

1. Functionality Testing: Verify that t-codes perform their intended functions accurately and meet the desired outcomes.

2. Data Validation: Test t-codes with various data sets, including edge cases and exceptions, to validate data integrity and consistency.

3. Integration Testing: Assess the seamless integration of transaction codes with other SAP modules and external systems. This usually reflects testing of business processes.

4. Performance Testing: Measure the response times and system resource utilization to ensure t-codes meet performance expectations.

5 .Security Testing: Evaluate the t-codes for any vulnerabilities or risks that could compromise system security.

6. UAT Testing: Conduct User Acceptance Testing (UAT), the final phase of software testing where end-users validate the system’s functionality and usability in a real-world environment.

7. Regression Testing: Conduct regular regression tests to identify any unintended consequences of code changes or system updates.

This is the SAP t-codes list of 40 of the most used codes in SAP ECC.
