SAP T CODE DOWNLOAD
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 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 usage.
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
