Canu2019t u201Ccommentu201D lines in Update Routine although in Change mode

Question

Hi,
There is an update rule between a datasource (2LIS_02_SCL) and ODS1 that I need to modify. When I double click on it, instead of seeing the old update rule that I am used to, showing the list of the fields I get some graphics with the links between fields in one group to the other.
The u201CRule groupu201D is set to u201CStandard Groupu201D.
I double click on the link between the fields of interest and changed u201CRule Typeu201D to u201CRoutineu201D and changed it to the change mode for changes.
I have an INCLUDE program from another project which performs the same tasks that I am trying to implement.
At a location where it states u201Cu2026insert your code here u2026u201D, I am able to bring in the lines from the other routine which does the desired job.
1.
The problem at this moment is that I canu2019t get COMMENT on all the previous codes which were in there. I tried deleting, and that also fails. As a result, I am getting errors.
Any help on this?
2.
Is that the right place to modify the routine?
3.
What is the difference between between between this approach of modifying update routines compare to the old one?
Thanks

Hi,
thanks so far:
I did exactly what you described. When I got to where to insert my code, I see that the system by default has METHODS, with declaration etc.
I want to ignore all those and simple insert the following. Donu2019t I need to comment on all the existing information that I do not need:
e.g. when I inserted the code below, and performed a u201Cchecku2019, it failed at a line (TYPE RSODSOCHECKONLY READ-ONLY,) which existed originally in the default code which read. I though I should be able to comment those out, but the system is not allowing me:
Attributs
    DATA:
      p_check_master_data_exist
            TYPE RSODSOCHECKONLY READ-ONLY,
*--my insert begins--
INCLUDE MY_UPDTE_RULE.
$$ end of global - insert your declaration only before this line   -
FORM Calc_Data
  TABLES   MONITOR STRUCTURE RSMONITOR "user defined monitoring
  USING    COMM_STRUCTURE LIKE /BIC/CS2LIS_02_SCL
           RECORD_NO LIKE SY-TABIX
           RECORD_ALL LIKE SY-TABIX
           SOURCE_SYSTEM LIKE RSUPDSIMULH-LOGSYS
  CHANGING RESULT LIKE /BI0/V0PUR_C01T-GR_QTY
           RETURNCODE LIKE SY-SUBRC
           ABORT LIKE SY-SUBRC.
$$ begin of routine - insert your code only below this line        -
fill the internal table "MONITOR", to make monitor entries
IF ( COMM_STRUCTURE-u2026u2026.
    perFORM ZZZZZZZ
       USING    COMM_STRUCTURE-u2026u2026
       u2026u2026
       u2026u2026
       CHANGING RESULT.
if the returncode is not equal zero, the result will not be updated
    RETURNCODE = 0.
else.
    RETURNCODE = 4.
endif.
if abort is not equal zero, the update process will be canceled
  ABORT = 0.
$$ end of routine - insert your code only before this line         -
ENDFORM.
*--end of my code--
Thanks
