how to browse files in sap ABAP OR apply for search help in the file field.

There are simple steps to browse files.

For the Report program you need to use the parameter :

  1. make parameter of type rlgrap-filename
Copy Code 


  PARAMETERS : gv_file TYPE rlgrap-filename.

2. Method 1 to browse file – call ‘F4_FILENAME’

Copy Code 


AT SELECTION-SCREEN ON VALUE-REQUEST FOR gv_file.
  CALL FUNCTION 'F4_FILENAME'
 *     EXPORTING
*      field_name = 'gv_file' 
    IMPORTING
      file_name  = gv_file.

For the Report program

Method 2 – browse the file For the Report program, you can use the global class cl_gui_frontend_services of method file_open_dialog .

Copy Code 


PARAMETERS : io_file TYPE rlgrap-filename.
Data : lv_filec TYPE rlgrap-filename.


AT SELECTION-SCREEN ON VALUE-REQUEST FOR io_file.
DATA: lv_title     TYPE string,
        lt_filetable TYPE filetable, "list of files you select in table
        lv_rc        TYPE i. "record count (directory path and file name)

  DATA: wa_filetable LIKE LINE OF lt_filetable.

  CALL METHOD cl_gui_frontend_services=>file_open_dialog
*    EXPORTING
*      window_title            = lv_title
*      multiselection          = abap_true "For multiple selection"
*    initial_directory         = '   '
    CHANGING
      file_table              = lt_filetable
      rc                      = lv_rc
    EXCEPTIONS
      file_open_dialog_failed = 1
      cntl_error              = 2
      error_no_gui            = 3
      not_supported_by_gui    = 4
      OTHERS                  = 5.
  IF sy-subrc = 0.
    READ TABLE lt_filetable INTO wa_filetable INDEX 1.
    IF sy-subrc EQ 0.
*      lv_file = wa_filetable-filename.
      io_file = wa_filetable-filename.
*      SET PARAMETER ID 'FIL' FIELD io_file.
      IF sy-subrc EQ 0.
        lv_filec = io_file.
      ENDIF.
    ENDIF.

At Selection Screen on Value Request event is used to display the possible values to be entered into the input field(search help).

This Method is for Module Pool Program

Step1: create screen ‘9001’ and make input box of field name ‘io_file’

step2 : after make input box you must declare filename(io_file) in top so that it will copy screen attribute to program attribute .

Copy Code 


// YYREX_TOP
Data: IO_FILE type rlgrap-filename.

Step3 : In “PROCESS ON VALUE-REQUEST” write field name which you want to help search help.

Copy Code 


// screen
PROCESS ON VALUE-REQUEST.
field IO_FILE module call.

Step 4: In this step you need to call method “method file_open_dialog” of global class “cl_gui_frontend_services“.

Copy Code 


MODULE call INPUT.
  DATA: lv_title     TYPE string,
        lt_filetable TYPE filetable, "list of files you select in table
        lv_record_count TYPE i."record count (directory path and file name)

  DATA: wa_filetable LIKE LINE OF lt_filetable.

  CALL METHOD cl_gui_frontend_services=>file_open_dialog
*    EXPORTING
*      window_title            = lv_title
*      multiselection          = abap_true "For multiple selection"
*    initial_directory         = '   '
    CHANGING
      file_table              = lt_filetable
      rc                      = lv_record_count
    EXCEPTIONS
      file_open_dialog_failed = 1
      cntl_error              = 2
      error_no_gui            = 3
      not_supported_by_gui    = 4
      OTHERS                  = 5.
  IF sy-subrc = 0.
    READ TABLE lt_filetable INTO wa_filetable INDEX 1.
      IF sy-subrc EQ 0.
      io_file = wa_filetable-filename.
    ENDIF.
  ENDIF.
ENDMODULE.
