Hi,

If at all you declare an EVENT ( Initialization or At selection screen) before Start of Selection, that event has to be closed by explicitely declaring the START-OF-SELECTION event, other wise the report won't execute, as the start of selection event won't trigger.

hi,

When user enters the values in the fields of selection screen and clicks on execute button, this event gets triggered. This event is basically for checking the values entered by the user for the fields of the selection screen i.e., data validity checking. This event is for entire selection screen. For example:

You are accepting carrid, connid, fldate from user and you don’t want to proceed if user enters no value for carrid and fldate. Using AT SELECTION-SCREEN can do this.

Select-options: carrid1 for sflight-carrid,

Connid1 for sflight-connid,

F1date1 for sflight-f1date.

AT SELECTION-SCREEN.

If carrid1-low ne ‘ ’ and fldate1-low = ‘ ’.

Error message.

Endif.

In this case, if both the fields are entered blank, then the user gets error message.

Basically, this event is for many fields on selection screen. Usually, it is for the fields which are logically related.

The standard selection screen in an executable program or in the logical database linked to it is automatically called between the INITIALIZATION and START-OF-SELECTION events.

You can define event blocks for these events in your program to change the selection screen or process user input.
