SAP T Code

What Are SAP T-Codes?

An SAP transaction code (T-Code) is a four-character shortcut that is used to access a transaction within an SAP system or application. Transaction codes provide direct access to the desired transaction from anywhere within the SAP system. Instead of using the menu or another means of accessing the transaction, you can start a function in a single step using an SAP T-Code. T-Codes can provide access to everything from user maintenance or authorization, workflow management, accessing SAP ABAP tables and dictionaries, running SQL queries, or transaction control. Every function in an SAP ERP system has a T-code associated with it. There are thousands of transaction codes available in different SAP systems and applications.

What Are SAP T-Codes?

Use of T-Code is performed by logging onto the SAP application using the SAP GUI or SAP Front End, placing the cursor in the SAP command field, typing the transaction code, then pressing enter. Depending on the role that a user plays within an organization, they will have different T-codes that are important to them. Administrators may focus on transactions related to that topic, while developers may use those connected to ABAP or SQL queries. Business users may use T-codes that relate to processing their daily tasks. Users can add T-codes that they use most frequently to a favorites list that allows them to access them more readily. SAP systems also provide the capability for users to create custom SAP T-codes by using the transaction SE91.

Key Considerations for SAPinsiders

If you’re moving to SAP S/4HANA and rely on transaction codes, then you need to determine what has changed. SAP has changed a number of things with the SAP S/4HANA release, and one of them is the T-codes that are available. This event session by Arghadip Kar walks through how to find which transaction codes have been deleted or placed in SAP S/4HANA that were available in SAP ECC. It also helps organizations that are planning for the move to SAP S/4HANA to plan around customizations in their existing system that may use decommissioned transaction codes.
You can map standard transaction codes to common phrases to make them easier to use and remember. A functionality that SAP provides is that of creating custom T-codes. But many users struggle with remembering the names of transaction codes despite the regularity of working with them. This article by Muhammad Ramzan walks through mapping standard transaction codes to common phrases to make them easier to remember, and easier to access from custom code. Following this approach ensures that authorization checks are not bypassed, and the authorizations to the actual transactions remain intact.
