VAT calendar different from Oracle calendar

[sandeepyam]

We have a situation here.

The calendar we follow is from Dec-Nov. Let me explain the issue here. The Jan-12 starts from 1-JAN-2012 to 28-JAN-2012, and FEB starts on 29-JAN-2012 and ends on 26-FEB-2012.
Now the operation run the VAT register after 2 days of period close, say on 30-JAn-2012 for the entire JAN month. on 3rd of FEB, few invoices that were stuck in the interface get auto invoiced. These invoices were for 30-JAn(FEB12 period).

Now unlike the normal calendar, VAT calendar is for an entire month, since this was created after the vat was run, this gets missed out and fines are paid by the comapny. How do we ensure this does not ahppen. I tried to take help of a simple extract to keep track of these trx which get created but client needs a permanent solution.


Thanks
