Problem with Code Abap in Include of EXIT_SAPLRRS0_001

Question

Hello all,  
I need to call to a function of conversion of dates from the include of the function EXIT_SAPLRRS0_001 but I cannot pass the parameters for the exporting, like I can declare these variables so that they pass to the other function mudule?, 
this way this now :
*&  Include           ZXRSRU01
DATA: l_s_range TYPE rsr_s_rangesid.
DATA: loc_var_range LIKE rrrangeexit.
DATA: t_date TYPE rsr_s_rangesid.
DATA:p_date TYPE d.
DATA: v_date1 TYPE d.
DATA: v_date2(6) TYPE c.
CASE i_vnam.
  WHEN 'ZPP_ACU_MES_SEM'.
    IF i_step = 2. "after the popup
      LOOP AT i_t_var_range INTO loc_var_range
      WHERE vnam = 'ZSEM_INDV'.
        CLEAR l_s_range.
obtener el primer dia de la semana de la fecha al 01mmyyyy
        v_date2 = loc_var_range-low(6).
        CALL FUNCTION 'WEEK_GET_FIRST_DAY'
          EXPORTING
            week    = v_date2    
         IMPORTING
            date    = v_date1
          EXCEPTIONS
            semana
            invalida...................

Hi Sonal, 
the error is not indicated explicitly but for the debbuging I could observe that they were not passing the parameters to the function module that calls, as I understand the variable it doesn't pass to another context like parameter and when using PARAMETERS in the INCLUDE of the EXIT_SAPLRRS0_001 it doesn't allow it 
CALL FUNCTION ' WEEK_GET_FIRST_DAY' 
          EXPORTING 
            week = v_date2 
          IMPORTING 
            date = v_date1 
          EXCEPTIONS 
            week 
            it invalidates.
