Hi Ashok,
Normally, when setting up a bank in bank rec, you normally never enter the opening balance for the bank account balance. If you do, you will see the same issue that you have reported. Sorry.

Setting up a new account in bank rec requires entering the actual statement balance for the opening reconciliation date, but not the opening balance.

You need to get your consultant to assist you with revising the opening balance entry from within your data with a Read/Write utility.

Best,
Brian
