How to create a customer-exit to calculate a week from a date

Question

Hi my Guru's,
I actually try to implement an Exit variable to calculate a week number from a characteristic date (0FINISHDATE) in my BEX report. Does anyone has an example of customer-exit which calculate a week number after giving a date in the popup.
What I really need is how to initialize the OFINISHDATE value in my Exit.
Any help will be appreciate,
Cheers,
MK2

Hi,
I  donot know this following workaround works properly are not. we have to wait for Our BW gurus' suggestions.
1) Create a formula variable with 'Replacement path' as processing type on Characterstic 0FINISHDATE.
2) Create one more Formula variable with 'customer exit' as processing type .
3) In Cmod
DATA: l_s_range type rsr_s_rangesid.
DATA: datein like sy-datum. "la caractéristique date
DATA: date2 like SCAL-WEEK. " déclaration de Résultat
DATA : NUMB1(2) TYPE N.
CASE i_vnam.
when 'FORMULA_VARIABLE2'.
IF I_STEP = 2. "after the popup
LOOP AT I_T_VAR_RANGE INTO LOC_VAR_RANGE
WHERE VNAM = 'FORMULA_VARIABLE1'.
CLEAR L_S_RANGE.
L_S_RANGE-LOW(8) = LOC_VAR_RANGE-LOW(8)
datein(8)  = L_S_RANGE-LOW(8).
here we are finding the Week no user entered date.
CALL FUNCTION 'DATE_GET_WEEK'
EXPORTING
DATE = datein
IMPORTING
WEEK = date2.
numb1 = date2+4(2)
CLEAR L_S_RANGE.
L_S_RANGE-LOW  = numb1.
L_S_RANGE-SIGN = 'I'.
L_S_RANGE-OPT  = 'EQ'.
APPEND L_S_RANGE TO E_T_RANGE.
ENDCASE.
