Convert BW3.x Start routine coding into BW 7.0

Question

The reversal load Update Rules (ICS  IC_TR) Start Routine
PROGRAM UPDATE_ROUTINE.
$$ begin of global - insert your declaration only below this line  -
TABLES: ZCHAR_SUBST.
DATA: sy_tabix like sy-tabix .
$$ end of global - insert your declaration only before this line   -
The follow definition is new in the BW3.x
TYPES:
  BEGIN OF DATA_PACKAGE_STRUCTURE.
     INCLUDE STRUCTURE /BIC/CS8ICS.
TYPES:
     RECNO   LIKE sy-tabix,
  END OF DATA_PACKAGE_STRUCTURE.
DATA:
  DATA_PACKAGE TYPE STANDARD TABLE OF DATA_PACKAGE_STRUCTURE
       WITH HEADER LINE
       WITH NON-UNIQUE DEFAULT KEY INITIAL SIZE 0.
FORM startup
  TABLES   MONITOR STRUCTURE RSMONITOR "user defined monitoring
           MONITOR_RECNO STRUCTURE RSMONITORS " monitoring with record n
           DATA_PACKAGE STRUCTURE DATA_PACKAGE
  USING    RECORD_ALL LIKE SY-TABIX
           SOURCE_SYSTEM LIKE RSUPDSIMULH-LOGSYS
  CHANGING ABORT LIKE SY-SUBRC. "set ABORT <> 0 to cancel update
$$ begin of routine - insert your code only below this line        -
  loop at DATA_PACKAGE .
    sy_tabix = sy-tabix .
    select single *
      from ZCHAR_SUBST
      where OLD_CHAR = DATA_PACKAGE-/BIC/CURR_CHAR .
    if sy-subrc is initial . " Candidate for a treatment
      DATA_PACKAGE-/BIC/KF1 = DATA_PACKAGE-/BIC/KF1 * ( -1 ) .
      DATA_PACKAGE-/BIC/KF2 = DATA_PACKAGE-/BIC/KF2 * ( -1 ) .
      modify DATA_PACKAGE index sy_tabix.
    else .
      delete DATA_PACKAGE index sy_tabix.
    endif .
  endloop .
  ABORT = 0.
$$ end of routine - insert your code only before this line         -
ENDFORM.
Start Routine for reversal load
Pls tell me how to write code for this.
Thanks

Hi
There are 2 approached for migration
1) Top down appraoch: here we start from top ( update rules) to bottom ( datasource) . In this approach Infosource is mandatory and all the routines will be taken care by the system no need to do anything manually.
2) bottom up approach : here we start from bottom ( datasource) to top ( update rules) . here Infosource is optional and once you migrate 3.x datasource all the transfer rules will get deleted so we need to record the transfer some where before mirgration. here we have to write maually the code invlolved in the transformation in BI 7.0 terminology.
Note: In bottom up approach it is better to use migration with export so that you can restore the datasource back to 3.x whenever any unexpected problem occurs.
You can do this By using the T code RSDS
