Migrating to SAP S/4HANA? Make sure all your processes are running properly by using the correct transaction codes. Discover all you need to know about T-Codes here.
Eventually, SAP customers will migrate over to S/4HANA because of the end-of-maintenance deadline in 2025. With this migration comes changes and updates to the current systems, including the use of different transaction codes (T-Codes). SAP technical consultants especially need to know which T-Codes are updated to efficiently plan their client or organization’s migration to S/4HANA.
Basically, transaction codes (T-Codes) are shortcuts to access and run functions in the SAP application. Instead of scrolling through the menu to find the function you’re looking for, you can simply enter the T-Code in the command bar to quickly find and execute the function in one step. T-Codes generally consist of a short combination of numbers and letters. Manually navigating the menu is time-consuming but also requires you to know where to look in the menu. With T-Codes, your processing time is significantly reduced.
For example, the T-Code MB01 (Post Goods Receipt for PO) is categorized in the Materials Management module for SAP and runs SAPMM07M, the application development R/3 inventory management program, upon execution.
With the introduction of SAP S/4HANA, many transaction codes became obsolete, and older ECC systems must adjust to the new codes. With SAP discontinuing service and maintenance for older ECC systems, SAP customers will eventually migrate to S/4HANA which uses a new list of T-Codes.
If your company hasn’t yet migrated to SAP S/4HANA, the SAP technical consultant you’ll hire for the transition will need to know the updated T-Codes to ensure an efficient migration!
It’s difficult to memorize all the T-Codes you need in SAP and even more so to remember all possible T-Codes. According to the SAP community, you can pull up the list of all T-Codes in the SAP application in a table view:
Now that you know how to find the full list of transaction codes, let’s look at the new T-Codes! When you’re using SAP S/4HANA, follow these commands:
The screen will pull up a table that compares the old T-Codes (“S_TCODE”) in a column with updated digits (“T_TCODE”) in another column.
If you want to find out the menu path for a specific T-Code in SAP, you can! There are two methods to find this information depending on what menu you’re using:
Save yourself time by adding all the T-Codes you usually use in your Favorites in the SAP menu. Make your transactions easily accessible:
There might not be a transaction code that does exactly what you need. Then that means, you just need to create a custom T-Code in SAP. Luckily, you can! Use the T-Code: “SE93” to create a new T-Code. After pressing enter, you will be prompted to answer a few questions on what you want that transaction code to do.
Sometimes, you might need to check who can access specific T-Codes to carry out a function. Use the T-Code: “SUIM” to open the User Information System. In this menu, you’ll be able to manage user permissions sorted by roles, profiles, and authorizations.
Unsure of how to find the T-Code for the function you’re looking for? Luckily, there are resources online that will help you navigate all the transaction codes. Including more information on SAP S/4HANA, here are a few helpful resources we recommend looking at:
