Creating new E business Tax regime and end dating migrated setups

----------Creating new E business Tax regime and end dating migrated Tax setups-----------

When creating transactions in a new regime, what date will the application check, the transaction Creation Date or the transaction date?

Scenario:
- The New Regime Date is Effective From 06-Jul-2012
- The Old Regime Date is End Dated on 05-Jul-2012

So for the following examples, the following questions apply:
1. What Regime will apply for these transactions?
2. Will the invoices be validated, and if so, what tax info will be stamped?

Example 1 - A Vendor invoice is entered with invoice date of 01-Jul-2012, and a create date of 07-Jul
Example 2 - A Vendor invoice with invoice date 10-Apr-2012 is reversed on 07-Jul-2012
