In authorization objects, authorization fields represent the values to be tested during authorization checks.
For more information about AUTHORITY-CHECK, see the keyword documentation of the ABAP Editor.
You can use the fields defined by SAP in your own authorization objects. If you create a new authorization object, you do not need to define your own fields. For example, you can use the SAP field ACTVT in your own authorization objects to represent a wide variety of actions in the system.
