What Transaction Date do you use on the Adjustment.  We are having difficulty printing Aged A/P reports for past period ends and reconciling them to the G/L - as a result of the dates we are using on our Adjustments. 

I try and use the same date as the invoice date for our adjustments and we also use the invoice date as our post date.  Very rarely is our post date different from the invoice date.  Keeping these the same will help when running your reports for accounts payable and general ledger, because both the dates are exactly the same and so are all adjustments; so they flow in and out as if you entered it correct the first time.
