Pagewise summation

Question

Hi
I have items in my main window, which will spill over to multiple pages. If that happens user wants summation such as
broght forward and carry forward. Can somebody help me how can I do that? Steps/sample code would be higly appriciated. Do I need to do changes in driver program or in script only?  How can I identify page break has happened? never done this.
Thanks in advance

Hi
You could actually do it with the help of SUMMING command. In SAP documentation they have given about that. In case still if you don't get the idea,  refer to the following code snippets.
In your SAP SCRIPT at variable window window write a sub routine, say WRITE_FR and call that in your driver program. In sap script, text element, as i said write a sub-routine.
///SAMPLE CODE///
/:define &SUM_TAB-TOT&
/:PERFORM SUM IN ZVA_SCRIPT(name of your program).
/:USING existing_field
/:CHANGING &SUM_TAB-TOT&
/:ENDPERFORM.
And in your driver program,
///SAMPLE CODE
TOTAL = 0.
LOOP AT PO_ITEMS WHERE EBELN = PO_MAIN-EBELN.
  PERFORM WRITE_FR USING 'MAIN' 'ITEMS'.
  TOTAL = TOTAL + PO_ITEMS-NETWR.
ENDLOOP.
PERFORM WRITE_FR USING 'TOTAL' 'TOTAL'.
FORM WRITE_FR(name of sub routine that you created in script) USING VALUE(WIND) VALUE(TELEM).
where WIND and TELEM are the text symbols.
CALL FUNCTION 'WRITE_FORM'
  EXPORTING
    ELEMENT                         = TELEM
   FUNCTION                       = 'SET'
   TYPE                           = 'BODY'
    WINDOW                          = WIND
IMPORTING
   PENDING_LINES                  =
  EXCEPTIONS
    ELEMENT                        = 1
    FUNCTION                       = 2
    TYPE                           = 3
    UNOPENED                       = 4
    UNSTARTED                      = 5
    WINDOW                         = 6
    BAD_PAGEFORMAT_FOR_PRINT       = 7
    SPOOL_ERROR                    = 8
    CODEPAGE                       = 9
    OTHERS                         = 10
IF SY-SUBRC <> 0.
  MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
         WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
  LEAVE PROGRAM.
ENDIF.
ENDFORM.
