Hi All,

I have a requirement like i need to compare two texts for example i need to retrieve the text from Purchase order as well from Purchase requisiton and i need to compare the both and if there is any difference i have update a flag. i am retrieving the texts from READ_TEXT function module.

Can any one suggest me some optimised way to compare the tex(If both the texts are same or different)??

Thanks in advance,

Joe

Check this FM MEDCMT_COMPARE_TEXTS

First translate them to UPPER CASE and then using an IF condition you can compare them .

Hi Joe,

You can use the below code snippet.

DATA: str1 TYPE string VALUE 'NiTesh',
      str2 TYPE string VALUE 'Nitesh'.
DATA: lv_length1 TYPE i,
      lv_length2 TYPE i,
      lv_temp TYPE i VALUE 1.
lv_length1 = STRLEN( str1 ).
lv_length2 = STRLEN( str2 ).
IF lv_length1 EQ lv_length1.
  DO lv_length1 TIMES.
    IF str1+0(lv_temp) NE str2+0(lv_temp).
      EXIT.
    ELSE.
      lv_temp = lv_temp + 1.
    ENDIF.
  ENDDO.
ENDIF.

Thanks

Nitesh

When using READ_TEXT function module, a table with all the 'lines' will be returned (tables parameter LINES). Compare the two internal tables and you will know, like this.


IF gt_lines1[] = gt_lines2[].  "gt_lines1 and 2 are internal tables per READ_TEXT.
* Same
ELSE.
*Different
ENDIF.
