Virtual KF using BADI

Question

Dear all,
My requirement is to create a virtual KF using BADI to populate a keyfigure ZWKDAY value in the bex query.
Condition -  I need to read 0calday from the cube and find it whether its a workday or not.
If its working day then my KF ZWKDAY should have value 1 else 0.
I created a BADI ZCL_IM_TEST_VIRTUAL for this.
I defined attributes as
P_KYF_RB_WKDC     Instance Attribute     Public     Type     I
P_CHA_0CALDAY     Instance Attribute     Public     Type     I
*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 'RB_RT_C01'.
    characteristic Calendar day
     l_s_chanm-chanm = '0calday'.
     l_s_chanm-mode  = rrke_c_mode-read. " rrke_c_mode-read / rrke_c_mode-no_selection
     APPEND l_s_chanm TO c_t_chanm.
    key figure DETERMINE WORKDAY
     l_kyfnm = 'RB_WKDC'.
     APPEND l_kyfnm TO c_t_kyfnm.
ENDCASE.
ENDMETHOD. 
METHOD IF_EX_RSR_OLAP_BADI~COMPUTE .
  FIELD-SYMBOLS:
  <fs_wkdc> type any,
  <fs_0calday> type any.
  Data: lv_workday(1) type C,
        lv_calday type sy-datum,
        l_flag   type char1 .
  Assign component P_CHA_0CALDAY of structure c_s_data to <fs_0calday>.
  Assign component P_kyf_RB_wkdc of structure c_s_data to <fs_wkdc>.
<fs_0calday> = sy-datum.
  CALL FUNCTION 'DATE_CONVERT_TO_FACTORYDATE'
    EXPORTING
    CORRECT_OPTION                     = '+'
      DATE                               =         <fs_0calday>
      FACTORY_CALENDAR_ID                = '01'
   IMPORTING
     WORKINGDAY_INDICATOR               =  l_flag
  EXCEPTIONS
    CALENDAR_BUFFER_NOT_LOADABLE       = 1
  if l_flag = '+'.
      <fs_wkdc> = 0.
  else.
      <fs_wkdc> = 1.
  endif.         
When I execute my query in RSRT transactionI am getting the following error.
"The function call of DATE_CONVERT_TO_FACTORYDATE failed; a field may have been assigned to the parameter DATE whose type is not compacitable".
When I tried to debug the code I found the type of <fs_0calday> is structure of c_s_data but I dont know how to solve this error. Any help on this is appreciated.....

Hi,
Instead of assigning type as any to your field symbol <fs_0calday>.
You will have to assign the same type as type of type of export parameter DATE of FM DATE_CONVERT_TO_FACTORYDATE.
Just change the attribute type and execute your query again.
