In the R/3 System, standardized functions are used. Standard functions always have the same name and are called in the same way in the various tasks of the R/3 System. They are a significant element in creating a consistent user interface. You should therefore try to use these standard functions as much as possible "in accordance with these guidelines".

This section lists and describes the R/3 standard functions. It also mentions the standardized function keys and the positions of the functions in the pull-down menus.

The standard functions are classified as follows:

• Functions for editing entire objects
• Functions for comparing and storing data
• Navigation functions
• Functions for editing table structures
• Basic control functions
• Other functions
