Virtual Key Figures its not populated when execute query

Question

Hi All
I did a BADI for populate a Virtual Key Figure, I follow the instructions of link
Link:[http://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/60e34f63-f44c-2c10-488e-c89b04e0ca7c?quicklink=index&overridelayout=true]
In addition I add the code section of data declarated on example of: CL_EXM_IM_RSR_OLAP_BADI section define: IF_EX_RSR_OLAP_BADI~DEFINE, only information that said:
  DATA: l_s_chanm   TYPE rrke_s_chanm,
        l_kyfnm     TYPE rsd_kyfnm.
  FIELD-SYMBOLS:
        <l_s_chanm> TYPE rrke_s_chanm.
I test the query on RSRT and the virtual Key Figure is "0.00" this look like if the virtual key figure is not populated.
I did other things like:
Set a Break Point on COMPUTE section of my BADI, I saw that the value is assigned, but I don't know how I can continue reviewing the pass of this value to result of query.
I generate again the query on RSRT.
My code is:
IF_EX_RSR_OLAP_BADI~DEFINE
method IF_EX_RSR_OLAP_BADI~DEFINE.
  data: L_S_CHANM   type RRKE_S_CHANM,
        L_KYFNM     type RSD_KYFNM.
  field-symbols:
        <L_S_CHANM> type RRKE_S_CHANM.
  case I_S_RKB1D-INFOCUBE.
    when 'ZGTO_OB2'.
      append 'ZVIRTKF' to C_T_KYFNM.
  endcase.
endmethod. 
IF_EX_RSR_OLAP_BADI~COMPUTE
method IF_EX_RSR_OLAP_BADI~COMPUTE.
  field-symbols <FS_ZVIRTKF> type any.
  P_KYF_ZVIRTKF = 16.
  assign component P_KYF_ZVIRTKF of structure C_S_DATA
  to <FS_ZVIRTKF>.
  <FS_ZVIRTKF> = 10 .
endmethod.
I will appreciate your recommendations, Thanks in advanced.

Thank you very much Sanganya
I saw this:
I put a break point on P_KYF_ZVIRTKF = 16., then I saw that P_KYF_ZVIRTKF obtain value 16.
Then on sentence: assign component P_KYF_ZVIRTKF of structure C_S_DATA
to <FS_ZVIRTKF> , when the system pass this line, I review the sy-subrc and is equal 4, as I understood the ASSIGN sentence did not be complete, the value shoul be 0.
Then when the system try to run the sentence: <FS_ZVIRTKF> = 10  the system send an Execution error that say:  GETWA_NOT_ASSIGNED...
  Error analysis
    You attempted to access an unassigned field symbol
    (data segment 32780).
    This error may occur if
    - You address a typed field symbol before it has been set with
      ASSIGN
    - You address a field symbol that pointed to the line of an
      internal table that was deleted
    - You address a field symbol that was previously reset using
      UNASSIGN or that pointed to a local field that no
      longer exists
    - You address a global function interface, although the
      respective function module is not active - that is, is
      not in the list of active calls. The list of active calls
      can be taken from this short dump.
Exactly the line selected with error is:
>>>>    <fs_zvirtkf> = '10.0'.
I will appreciate your help
Thank you
