SAP Help

Field Help
Use F1 for help on fields, menus, functions and messages.
-> F1 help also provides technical information on the relevant field. This includes, for example, the parameter ID, which you can use to assign values to the field for your user.
-> Use F4 for information on what values you can enter. You can also access F4 help for a selected field using the button immediately to the right of that field.
-> If input fields are marked with a small icon with a checkmark, then you can only continue in that application by entering a permitted value.
. You can flag many fields in an application to make them either required entry fields or optional entry fields. You can also hide fields using transaction or screen variants or Customizing.
