A transaction code consists of letters, numbers, or both, and is entered in the command field at the top of any SAP GUI screen. Each function in SAP ERP has an SAP transaction code associated with it.
Use
A transaction code is used to access functions or running programs in the SAP application more rapidly. By entering a t-code instead of using the menu, navigation and execution are combined into a single step, much like shortcuts in the Windows OS. SAP transaction codes can be entered into the Transaction code field to navigate the user directly to the screen or program task bypassing the SAP menu. This is the preferred method of using SAP because navigating the menus is time-consuming and you need to know where to look in the menus. However, the user must know the transaction code. The alternative to using and having to know the transaction codes is to set up a favorites menu which is a customized menu established by the user. The favorites menu can be structured by the user to coincide with the procedural usage of the SAP software. For example, if the user is an Accounts Payable officer a customized menu of accounts payable functions could be created to enhance SAP use.
Example
Users can create a new session and start a new transaction in one step by entering /o followed by the transaction code e.g. /oFB60 Example Transaction codes MM01 creation of Material Master XK01 Creation of Vendor Master XD01 creation of Customer Master FB60 Accounts Payable Invoice Entry FB65 Accounts Payable Credit Note Entry FK10N Display Accounts Payable Balances The transaction for MM module starts with M.
