Date of VAT Register is not fixed when the transaction is settled & paid, allowing report to be changed - Validation required

When the Date of VAT Register functionality turned on which allows user to change the date of VAT transactions already settled, without creating a contra entry to ensure the net movement is zero.

Due to this same transaction could be settled multiple times to the VAT authorities, which is incorrect.

Expectation: System should give validation such as any notification which alerts the user when they try to change the data of VAT register for already settled and paid transactions.
