hello all,

i am extracting file name from file path but i want to add some validation on filename

i.e filename should be in "CITI2010072101" format.

how to validate i/p string.

format is like citi date '01'(any code from 00 to 09)

hi,

use the function module PC_SPLIT_COMPLETE_FILENAME to seperate the filename from path and concatenate as per your requirements...

with regards,

DATA: v_filename TYPE fileintern VALUE 'CITI2010072101',
      v_date TYPE datum.

IF v_filename+0(4) = `CITI`.
  v_date = v_filename+4(8).
  CALL FUNCTION 'DATE_CHECK_PLAUSIBILITY'
    EXPORTING
      date                      = v_date
    EXCEPTIONS
      plausibility_check_failed = 1
      OTHERS                    = 2.
  IF sy-subrc = 0.
    IF v_filename+12(2) GE '01' OR v_filename+12(2) LE '09'.
      WRITE: / 'File Name is correct'.
    ELSE.
      WRITE: / `Error in filename. Sequence is incorrect` .
    ENDIF.
  ELSE.
    WRITE: / `Error in filename. Date is incorrect` .
  ENDIF.
