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.

What are Transaction Codes (T-Codes) in SAP?

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 in SAP, 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.

Why you should pay attention to the new T-Codes

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!
