Hello PwC Antigua,
OK - well there is a much easier way to deal with an incorrect take-on balance. In the company profile, turn off the option which prevents posting an entry to the bank account g/l. Then post a receipt or payment (depending on whether you need to raise or lower the bank balance) with the offsetting entry to be the bank g/l account. Post the transaction. The g/l entries will net to zero. Make sure you change the entry back in the company profile so that users don't inadvertantly post entries to the bank g/l account.
When you are talking about "linked to", are you referring to the bank g/l account being affected by the transactions, or the a/r and/or a/p clearing accounts?
