Error: "That reference number has already been entered for this cash account."

Check number has already been used with the selected cash account.

NOTE: To find if the reference number has been used, open the Audit Trail Report and filter by that reference number using a wide date range (maybe 01/01/1990-01/01/2020). The Audit Trial will be more efficient in finding the duplication, as Edit, Find Transactions only finds actual transactions and will not find beginning balances (which also require a reference number to be saved).
