   - enter parameters (for entering single values).
   - provide selection criteria (complex selection options for value lists and value ranges) that can be used to supply an executable program with values to work with.
 - Can be created using special ABAP statements in the global declaration part of executable programs

 - Selection screen events 
   - Used to individually evaluate selection screen elements, e.g. a specific parameter.
-  - In many cases, the events can be used for input validation (this should not wait until `START-OF-SELECTION`). If your custom input validation fails on an input, you can raise a message (e.g. a message of type `E`: `MESSAGE 'Error' TYPE 'E'.`) and allow the user to edit the input again.
