This event keyword defines an event block for initializing an executable program. The associated event is raised by the ABAP runtime environment during the flow of an executable program, directly after LOAD-OF-PROGRAM and before the selection screen processing of any existing standard selection screen. This enables the input fields of the selection screen to be initialized once only, including those fields defined in the logical database associated with the program.


When an executable program defines a standard selection screen, it is called again by the ABAP runtime environment after execution, which raises the event INITIALIZATION again. In this case, the initialization of parameters or selection criteria of the selection screen is ignored, however, because they are automatically supplied with the preceding user input from the selection screen during the selection screen event AT SELECTION-SCREEN OUTPUT. To initialize the selection screen explicitly for each call, the event AT SELECTION-SCREEN OUTPUT must be used.


Prefills a parameter on the standard selection screen of an executable program when the event INITIALIZATION is raised.
