this is used to know the possible values whican can be given as input to p_file.

on any field when u click on f4 this functionality works

U can populate the possible values either into an internal table and use it with the help of a function module or if it is a database field, it does come by default.

Hi Pandu,

On value request means that you are requesting for probable values.This event will be triggered when u press F4 help in the selection screen on the field specified in the event. The code written bellow this event will be triggered only if u press F4 on that particular field. So please take care this while coding.

Hope this clears ur doubt.

Regards,

Vinod.
