Suggestion has been added to suppress vendors with a net zero balance (as of the report date), even if there are offsetting and unmatched transactions.

We cannot suppress a vendor on the Open Payables report (that has the field Outstanding Balance = 0) if one of these offsetting transactions is dated after the report date (and thus is excluded from the report), because then the report totals will not match up to the GL. Only if the vendor balance is zero as of the 'calculated as of' report date.
