Opening Balance for PLA register

Hi

Before go live we need to update Excise register balances, i.e. Updating excise registers with opening balances.

For Item and amout we can user RG Manual entry screen and /or Misc receipt (RG Update)

But for PLA, oracle do not support any manual entry. So to update the opening balance, below are the steps we are thinking of.

1. Create PLA invoice from IL Payable Responsibility

2. Create dummy bank to pay this PLA Invoice. This is because the actual payment is made in legacy system. So we can not make the real payment.

3. Ack the Payment.

Is there any other way to update the PLA Opening balance ? Creation of Dummy bank for one transaction is conern for client.
