Hello all,

Can anyone guide me on the procedure to provide f4 help on a parameter in the selection screen.

My requirement is:

- parameter declared of type 'localfile' inside a selection-screen declared as a 'window'. & provide a f4 help to browse a local file.

Thanks a lot in advance.

CALL METHOD cl_gui_frontend_services=>file_open_dialog

EXPORTING

INITIAL_DIRECTORY = 'C:Temp'

MULTISELECTION = 'X'

CHANGING

file_table = lt_file_names[]

rc = lv_subrc

Hi Krishna,

You need to pick file name from the explorer browser, for that you may use the function module 'F4_FILENAME'.

parameters p_fnam type localfile.

define the event at selection-screen

At selection-screen on value-request for p_fnam.

CALL FUNCTION 'F4_FILENAME'

EXPORTING

program_name = sy-cprog

dynpro_number = sy-dynnr

FIELD_NAME = ' '

IMPORTING

file_name = p_fnam.

this will upload the filename into the variable p_fnam, which can be further used.

Hope this helps in resolving your issue.

Thanks & Regards,

Sachin Dargan
