The "Transaction already exists - save anyway?" error occurs when another transaction of the same type has been saved using the same number.
To locate the other transaction
- Make a note of the transaction number (invoice number, check number, etc.) for the transaction you're trying to save.
- Select the Magnifying glass in the Toolbar.
- Select Advanced Search.
- Select All transactions, Reference no, Contains and enter the number of the transactions that you are trying to save.
- Select Search.
This will show which transaction is causing the error to appear. You can choose to renumber and resave the old transaction, give the new transaction a different number before saving it, or save the new transaction with the same number.
