"Transactions with Missing Dissection" error

When running a transaction check or trying to finalise a BAS, I am getting an error message saying 'You have transactions with no associated dissections, or the transaction amount does not equal the dissection total".

If you receive this message and the subsequent report shows transactions that don't have dissections, please make a copy of your data available to the support team at Practical Systems. This could be either via an attachment to an email, or sending your data to the Data Warehouse. Either way, please email or call the support team to let them know of your problem.
