Hi,

This might be helpful.

Please check these program :

DEMO_SELECTION_SCREEN_BASIC

DEMO_SELECTION_SCREEN_EVENTS

DEMO_SELECTION_SCREEN_F1

DEMO_SELECTION_SCREEN_F4

PROCESS ON HELP-REQUEST. User-programmed F1 help

Effect

POH event for user-programmed help. Modules in this event are processed when the user presses F1 with the cursor positioned on a screen field. In the subsequent FIELD statements, you can specify a data element supplement (or determine one in an application module). The texts are then displayed by the help system.

Examples

FIELD XY WITH '0001'.

Displays data element addition 0001 for field XY.

FIELD XY WITH variable.

Displays the data element supplement with the number contained in variable for the field XY.

FIELD XY MODULE XYZ WITH variable .

The relevant data element supplement is determined in module XYZ, where it is placed in variable. Use this procedure whenever you cannot determine the correct data element supplement until the F1 event.

PROCESS ON VALUE-REQUEST. User-programmer F4 help

Effect

Event in user-programmed help that occurs when the user presses F4 with the cursor positioned on a screen field. The modules specified in the subsequent FIELD statements are called instead of the SAP help system.

Example

FIELD XY MODULE XYZ

Module XYZ determines the value of field XY and places it in the input field on the screen.
