Change Offset value of input node in APO order

Question

Dear experts,
in order to accomodate overlapping scenario in APO I calculate and update offset value of input nodes of apo planned orders. To do so I use BADI /SAPAPO/RRP_SRC_EXIT method RRP_USEX_PLORD_CREATE. I activate the BADI using heuristic SAP_PP_021. it works fine for APO planned orders. However It is not possible to change production order nodes.
I have tried using a heuristic (copy of SAP_PP_012) that uses Function Module /SAPAPO/RRP_LC_ORDER_MODIFY. However I can not change orders as I got a livecash error.
I also tried /SAPAPO/RRP_LC_ORDER_CHANGE. In this case I did not have LC error but I still order offset value was not changed.
do you have any idea on how to proceed? What I really want is a method to change input nodes of production orders in APO.
Thank You,

Hi Anup,
In customer exit variable you will have to populate your 0FISCPER characterstics,
You can populate it based on system date, use the FM DATE_TO_PERIOD_CONVERT and you will get current period based on your system date and Fiscal Year variant.
After that you can just modify these values. and populate your 0FISCPER characteristics.
If you have to do this calculations based on user input date then follow the same procedure but instead of system date you will have to pass the date entered by customer to this FM.
Refer the following sample code snippet,
IF i_step = 2.
      DATA:l_vy7(4) TYPE c,
           l_vm7(3) TYPE c.
      CLEAR: l_s_range,loc_var_range.
      LOOP AT  i_t_var_range    INTO  loc_var_range   WHERE  vnam = 'input var'.
        call the FM convert to period here and give user input date.
        l_vy7 = l_vy7 - 1.
        l_vm7 =  loc_var_range-low+4(3).
        CONCATENATE l_vy7 l_vm7 INTO loc_var_range-low.
        l_s_range-low      = loc_var_range-low.
        l_s_range-sign     = 'I'.
        l_s_range-opt      = 'EQ'.
        APPEND l_s_range   TO   e_t_range.
        EXIT.
      ENDLOOP.
    ENDIF.
