Answer to your questions:

1. version- 6.8A if QI
Batch listing showed correct account codes. The were newly created invoces and CN's. Mulitple 'customer Codes' were used. DIC showed now errors in AR.

With respect to removing the %E66 code from the credit notes, how is this done. When I went into maintain invoices, all i found was the filenames for invoices, not CN's?

Thanks,

Ken
