Hi Ralph Allan,
To follow on from that thought - using Adagio OLEDB the programm could load the entire chart of accounts for validation each time the external program was launched. Loading the chart wouldn't take more than a minute.
I don't see us validating the g/l distribution during the import, unless field verification was turned on. Even then - imported transactions are assumed to have some amount of validation previously performed.
Still, perhaps we can look at this the next time we are "mucking about" in import invoice in Adagio Payables.
