Hi Gurus ,
How can I extract the data from a XSTRING  .
I have to get the data which is filled in the survey form the data is getting saved in form of xstring .
Someone told me that there is a standard FM for that . but I am not able to find .
Please reply with the FM in case some one knows about it .
Thanks in advance .
The following code works as of 7.0 (in any SAP system):
FORM XSTRING_TO_STRING USING input TYPE xstring CHANGING output TYPE string.
TYPES : BEGIN OF ty_struc,
          line TYPE c LENGTH 100,
        END OF ty_struc.
DATA lt_char TYPE TABLE OF ty_struc.
DATA length TYPE i.
length = xstrlen( input ) / cl_abap_char_utilities=>charsize.
CALL FUNCTION 'SCMS_XSTRING_TO_BINARY'
  EXPORTING
    buffer                = input
  tables
    binary_tab            = lt_char.
CONCATENATE LINES OF lt_char INTO output RESPECTING BLANKS.
output = output(length).
ENDFORM.
