Not allow to save the billing document in the back date if FI period closed

hello,
Has your query been solved.
if not , here is the solution.
go to the program RV60AFZZ. This is the exit for billing.
In that there is a form called
FORM userexit_number_range USING us_range_intern.
in the form you have to write the code.
variables to pass for the function module.
DATA: lv_buper  LIKE  t009b-poper,
        lv_gjahr  LIKE  t009b-bdatj.
CALL FUNCTION 'DATE_TO_PERIOD_CONVERT'
      EXPORTING
        i_date               = syst-datum
        i_periv              = 'V3'
     IMPORTING
       e_buper              = lv_buper
       e_gjahr              = lv_gjahr
in lv_buper you will get the last posting period which is open ie the posting period month.
based on lv_buper you get , you can write your validations.
You have to remember that the posting period which u get is based on the fiscal year.
hope that helps.
reward if useful.
cheers,
