Bank Reconciliation

Our client has many unmatched bank statement transactions every month.

The client would like to mark these transactions as quarantined and NOT resolve the issue by impacting the GL (i.e. they don’t want to use a suspense account), but still need to reconcile the bank account. Is there a standard way of doing this in standard AX, or is there a third party product out there that can achieve this?

By way of example:
A deposit of $500 is made into the entities Bank Account on 30/07/14. The accounts department do not know what Customer made this payment as no paperwork matches the deposit. On the 02/08/14 the Bank Reconciliation must be finalised and posted as at 31/07/14. Instead of posting a General Journal to a suspense account for the unknown $500 deposit, this should be flagged as an “unidentified deposit”. This will ensure that the unreconciled amount is $0.00 and the user can finalise the Bank Reconciliation.
