Populate new fields in DSO (DBTable) with ABAP routine

Question

Hi,
I've added a couple of fields to a DSO. The DSO contains a large number of records (60m+) and I have a tight window to cutover so the activation time would be an issue if I use a loop transformation. Therefore, I am looking to populate the additional fields directly in the Active table using an ABAP routine.
One of the fields is a key figure to be derived from an existing CHAR field so would need to apply some logic during update, such as IF <CHAR_FIELD> CA 'ABC'. <KYF_FIELD> = 1 etc.
Aside from fairly basic Start Routines my ABAP is very poor so was wondering if anyone can help me with the syntax or, preferably some sample code to achieve this.
Thanks in advance,
Ad

Hi,
   In transformation of the cube, choose routine  for char E.
   There you can assign value in RESULT field. Actually RESULT field is assigned to E, find the code below,
*--  fill table "MONITOR" with values of structure "MONITOR_REC"
*-   to make monitor entries
... "to cancel the update process
   raise exception type CX_RSROUT_ABORT.
... "to skip a record
   raise exception type CX_RSROUT_SKIP_RECORD.
... "to clear target fields
   raise exception type CX_RSROUT_SKIP_VAL.
  (* insert your abap code here to find the value of E*.)
     RESULT =                     * assign the value you got for E here.
