Change the output length of a field?

Question

I have a table that will write a field ] with 18 characters since that’s the length in the table, but instead the content of the field should be copied into a variable which length is 30 characters and then be written in to the text file (as a result blank spaces will be added at the end of the content of the variable).  do i need to declare this in a DATA statement? if so, how?

Hi.
I think its quite similar with a issue I had a time ago and I solved it using copying RESPECTING BLANKS using concatenate command.
It will copy your 18 character fields adjusted to right position and respect blanks in the left side, in TXT file, so respecting 30 characters positions to this field in the file.
e.g.:
If you are trying to concatenate various fields per line into TXT, use this example that worked to me:
LOOP it_table.
your_30_char_field = matnr.
SHIFT your_30_char_field RIGHT DELETING TRAILING space.
concatenate .....field1 field2 field3 your_30_char_field ... fieldN into ls_file RESPECTING BLANCS.
append ls_file to IT_file.
ENDLOOP.
I do not know if you are using gui_download. So it's the case, use this way:
  CALL FUNCTION 'GUI_DOWNLOAD'
    EXPORTING
      filename                  = lc_filename
      filetype                  = 'ASC'       " important
      trunc_trailing_blanks_eol = ''     " Important
    TABLES
      data_tab                  = it_data_out.
best regards.
