So in this case, the file in exporting is the name of the file to be checked, is that correct?

Thanks,

hi Zhu,

Check this out

data: file_name type string.

data: <b>result type abap_bool.</b>

data: rc type i.

file_name = txt_work_file.

call method cl_gui_frontend_services=>file_exist

exporting

file = file_name

receiving

result = result

exceptions

cntl_error = 1

error_no_gui = 2

wrong_parameter = 3

others = 4.

This is a RECEIVING parameter. You do not enter anything. SAP will fill this field for you. It is the confirmation of whether or not the file exists in the specific path provided in your FILE parameter.

This is a RECIEVING parameter, and you can use a TYPE ABAP_BOOL variable here. It will be "X" if the file exists, blank if not.

type-pools: abap.

data: result type abap_bool.
data: filename type string.


filename = 'C:test.xls'.


call method cl_gui_frontend_services=>file_exist
  exporting
      file =  filename
  receiving
     result = result .

if result = 'X'.
  write:/ 'Yep, file is there'.
else.
  write:/ 'Nop, file isnt there'.
endif.

Result is of type ABAP_BOOL which is TYPE C length 1. It takes two values, space and 'X'.
