Upload a Comma Delimited CSV file that contains commas in data

Some Comma Delimited CSV files will contain commas in the data fields and this causes problems in loading the file into our system. I don't think there is a standard function module to do this but I will share a small code snippet which will save someone to re-invent the wheel.

Here is a sample of the comma delimited CSV text file, you can copy below text then paste in notepad and save as c:\Temp\Book1.csv file.

10,Shafiq,"Sacramento, CA"
11,Willie,"New York, NY"
12,Conner,"Seattle, WA"

Here is the sample program which will read this file and store in a table that will preserve the commas in the city field:
Upload from Local PC:

TYPES: BEGIN OF kcde_intern_struc.
        INCLUDE STRUCTURE  kcde_cells.
TYPES: END OF kcde_intern_struc.


DATA: l_intern    TYPE  TABLE OF kcde_intern_struc WITH HEADER LINE.

DATA: BEGIN OF it_output OCCURS 0,
        id(10) TYPE c,
        name(20) TYPE c,
        location(20) TYPE c,
  END OF it_output.
DATA: wa_output LIKE LINE OF it_output.
DATA: v_index TYPE i.

FIELD-SYMBOLS : <fs>.


CALL FUNCTION 'KCD_CSV_FILE_TO_INTERN_CONVERT'
  EXPORTING
    i_filename      = 'C:\Temp\Book1.csv'
    i_separator     = ','
  TABLES
    e_intern        = l_intern
  EXCEPTIONS
    upload_csv      = 1
    upload_filetype = 2.

LOOP AT l_intern.
  MOVE : l_intern-col TO v_index.
  ASSIGN COMPONENT v_index OF STRUCTURE wa_output TO <fs>.
  MOVE : l_intern-value TO <fs>.
  AT END OF row.
    APPEND wa_output TO it_output.
    CLEAR wa_output.
  ENDAT.
ENDLOOP.

Upload from Unix Server

DATA: BEGIN OF itab_upload OCCURS 0,
       str(4096),
      END OF itab_upload.
DATA: l_intern    TYPE  TABLE OF kcde_intern_struc WITH HEADER LINE.

  OPEN DATASET p_path FOR INPUT ENCODING UTF-8 IN TEXT MODE.
  DO.
    READ DATASET p_path INTO itab_upload.
    IF sy-subrc NE 0.
      EXIT.
    ENDIF.
    APPEND itab_upload.
  ENDDO.
  CLOSE DATASET p_path.
  PERFORM separated_to_intern_convert IN PROGRAM saplkcde
                                  TABLES itab_upload l_intern USING ','.
  LOOP AT l_intern.
    MOVE : l_intern-col TO v_index.
    ASSIGN COMPONENT v_index OF STRUCTURE wa_output TO <fs>.
    MOVE : l_intern-value TO <fs>.
    AT END OF row.
      APPEND wa_output TO it_output.
