DSO activation failure due to trailing space

Hi All,

I'm facing DSO activation failure due to lowercase, space at leading,b/w and trailing spaces.

I have fixed for

1)lower case using translate keyword,

2)gaps between the letters  using "condense no-gaps"

3) Leading space using shift "deleting leading space"

by placing the code in existing expert routine.

But when I use "Shift deleting trailing space" keyword for removing trailing space,it is not working causing activation failure.

Can you please suggest alternate way to fix the trailing space.

I have searched the below code,but not sure how it works

REPLACE ALL OCCURRENCES OF cl_abap_char_utilities=>cr_lf IN RESULT WITH

' '.

REPLACE ALL OCCURRENCES OF cl_abap_char_utilities=>horizontal_tab IN

RESULT WITH ' '.

REPLACE ALL OCCURRENCES OF cl_abap_char_utilities=>vertical_tab IN

RESULT WITH ' '.

REPLACE ALL OCCURRENCES OF cl_abap_char_utilities=>newline IN RESULT

WITH ' '.

REPLACE ALL OCCURRENCES OF cl_abap_char_utilities=>form_feed IN RESULT

WITH ' '.

REPLACE ALL OCCURRENCES OF cl_abap_char_utilities=>backspace IN RESULT

WITH ' '.

regards
