Hi...

We have different Events that are triggered while processing SELECTION-SCREEN:

1. AT SELECTION-SCREEN OUTPUT.

Triggered before displaying the Selection Screen.

2. AT SELECTION-SCREEN .

Triggered before leaving the Selection Screen, once the user selects any button

So it is used for all validations.

3. AT SELECTION-SCREEN ON <field>.

Same as AT SELECTION-SCREEN .

To validate a Specific field

4. AT SELECTION-SCREEN on VALUE-REQUEST FOR <FIELD>.

Triggered if F4 Help is requested on field.

Reward if Helpful

At Selection-Screen.

The event is processed when the selection screen has been processed (at the end of PAI ).

Validation & Checks of inputted values happen here

At Selection-Screen :

If an error message occurs in this processing block, the selection screen is redisplayed with all of its fields ready for input.

After further user input, AT SELECTION-SCREEN is executed again. This allows you to check input values for consistency.

….ON VALUE-REQUEST FOR psel_low_high.

When the user selects this pushbutton or presses F4 for the field, the event is executed. You can thus implement a self-programmed possible entries routine for the input/output fields of the selection screen.

This addition is only allowed with report-specific parameters (PARAMETERS ) or selection options (SELECT-OPTIONS ).

Hope this helps

reward if useful
