Hi,

First you capture the input which you have given in the Issue no field using the following FM

Use FM 'C14Z_DYNP_READ_FIELD'

For Instance it should be like below

Data : v_field(255) type c.

CALL FUNCTION 'C14Z_DYNP_READ_FIELD'

EXPORTING

i_program = sy-repid

i_dynpro = sy-dynnr

i_fieldname = 'V_PLANT' "here specify your own field which u want to read

i_flg_steploop = ''

CHANGING

e_value = v_field. "Specify the variable inwhich u want to have the value and based on that u select other F4 help entries

and then based on the selected value select the data to shown in the select search help and apply that internal table in second field search help FM call.

Use the FM "F4IF_INT_TABLE_VALUE_REQUEST"

Hi Srinath,

I understood that u need F4 help which redirects to the folders in the local system.

The FM used for this is 'F4_FILENAME'

Ex :

CALL FUNCTION 'F4_FILENAME'

IMPORTING

FILE_NAME = FILENAME. -

---

> Decleration FILENAME LIKE RLGRAP-FILENAME.

Hope this will be helpful to you.

Hi Srinath,

how to write the code in dynpro..

PROCESS AFTER INPUT.
* Module Screen Exit and Cancel Operation
  MODULE exit_screen_1020 AT EXIT-COMMAND.

*F4 Help

  FIELD p_filename MODULE f4_choose_filename.


Module  f4_choose_filename INPUT . "INPUT
    CALL FUNCTION 'F4_DXFILENAME_TOPRECURSION'
      EXPORTING
        i_location_flag = 'P'
        i_server        = ' '
        i_path          = p_filename 
        filemask        = ' '
        fileoperation   = 'R'

Hi,

Use FM 'F4_FILENAME' . Pass your selection parameter to this FM.

Hi,

In screen flow logic (jn POV - PROCESS ON VALUE-REQUEST) you can use any of provided above FMs or you can do this using cl_gui_frontend_services class and its static method file_open_dialog .

Check this out: [read a file from directory using cl_gui_frontend_services|http://sapprograms.blogspot.com/2008/12/read-file-from-directory-using.html]

Please note. Althought using FMs is not banned, it is recommended to go for ABAP OO aproach, where new classes are derived from old FMs imporving their perfomance or filling some "gap".

Hi,

Use the following function module.

parameters : p_url TYPE localfile.

CALL FUNCTION 'KD_GET_FILENAME_ON_F4'

EXPORTING

program_name = syst-repid

dynpro_number = syst-dynnr

static = 'X'

mask = ',Excel Worksheet,*.XLS'

CHANGING

file_name = p_url

EXCEPTIONS

mask_too_long = 1

OTHERS = 2.

Here p_url must be the parameter value also.

you write this function module in

process ON VALUE-REQUEST.

field p_url module browse_file_9000.

where browse_file_9000 is the module which will have the function module call.

Using this FM, you can restrict the file type also. For example, the above example will open only Excel file. If you want to open only text file, then in mask parameter you write as ',Text document,*.txt'.

Thanks and regards
