we have Provision from sap like load-of-program.

in your code

write this event

load-of-program.

under that you process the code for as follows....

if sy-tcode = 'Z......'.

Then proceed otherwise raise the message like 'you have to run this report through transaction code only.

Hi,

check out this code......

PARAMETERS : P_VB TYPE VBELN.

AT SELECTION-SCREEN.

IF SY-UCOMM = 'ONLI' OR SY-UCOMM = ''.

CALL SCREEN 1000.

ENDIF.

END-OF-SELECTION.

WRITE : 'HI !'.

( If it is a module-pool call the user-defined screen

You can give Your own pf-status : ' set pf-status 'XXXX' ' (in report also at event 'selection-screen output' ) ; DEFINE YOUR OWN FCODE and do the processing if sy-ucomm is the defined one.

Hi Alok,

I guess u want to execute the code as an when data is entered in input field.

For this,

U have to use event "data_changed" of class "cl_gui_alv_grid".

Declaration:

CLASS lcl_event_receiver DEFINITION .

PUBLIC SECTION .

METHODS:

handle_data_changed

FOR EVENT data_changed OF cl_gui_alv_grid

IMPORTING er_data_changed.

ENDCLASS.

Implementation of class:

CLASS lcl_event_receiver IMPLEMENTATION .

METHOD handle_data_changed.

PERFORM data_changed USING er_data_changed .

ENDMETHOD .

ENDCLASS .

Form (actual code)

FORM data_changed USING rr_data_changed TYPE REF TO

cl_alv_changed_data_protocol.

DATA: ls_mod_cells TYPE lvc_s_modi.

DATA: ls_cells TYPE lvc_s_modi.

WHEN 'Input field name'.

CALL METHOD rr_data_changed->get_cell_value

EXPORTING

i_row_id = ls_mod_cells-row_id

i_fieldname = ls_mod_cells-fieldname

IMPORTING

e_value = lv_variable.

Here, lv_variable of type input field is a local variable to store the data enterd in the field.

Pooja Bajaj.

hi there...

i dont think ,the method given above will help. it will work wenever any key is pressed and not just on the press of Enter.

I would suggest you to open ur program in se80, there, u will get an option to set the aplication toolbar. in that u can define the functionality on the press of enter.

do reward if helpful or get back with further query.
