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

Question

Can anybody help me please. My FI period for october is closed. But there are still some open delivery documents in billing due list for October. So now let say on 7th december if i will make the billing documents by giving the date 30.11.2007 logically as FI period is closed it will allow to save the billing document but will not pass to accounting.
So this normaly happening in my industry endusers are creating the billing documents in the back date even after the period close so all the documents come into VFX3.
So can any body help me? Can we have any check if the FI period is closed for a perticular months if we will try to make the billing documents in the closed period it will not allow to generate the billing document rather saving the documents and blocking for accounting.

Dear laxmikanta
I also not come across the situation what you said and hence dont have much idea about authorization group.
However, on going through the F1 help, it says
<b>Procedure</b>
    If only a limited set of users is to be able to post in a particular
    posting period, proceed as follows:
             o   Add the posting period authorization (authorization object
        F_BKPF_BUP) to the authorizations of the selected users. Assign an
        authorization group (e.g. '0001').
              o   Enter the account type '+' for the posting period variant to which
        the restriction is to apply. Enter the period(s) whose use is to be
        restricted in the first period, those which are available to all
        users in the second period, and the authorization group (e.g.
        '0001') in the last column.
<b>Examples</b>
    A posting period can be successively restricted. If, e.g. 10 users have
    the posting period authorization with authorization group '0001', and 3
    of these 10 users also with authorization group '0002'.
    If the period is only to be accessible to the 10 selected users the
    authorization group '0001' is entered in the posting period variant.
    Access can later be restricted to the remaining 3 users by entering
    '0002'.
From the above, I feel your requirement can be met.
