Thanks, Andrew for your quick response. I am still not able to reverse. AFter following your direction, I see the status has changed from O to O->R, then I posted and status changed to R. The G/L now has a retrieved but unposted batch with my reversed checks showing $0 amounts in my G/L "accounts payable clearing" account as debits and credits. Do I still need to void the checks in Bank Rec Module, as I traditionally do to get the G/L cash and expense account to reflect the voided checks? Also, how do I make the adjustment to void the invoice in A/P, step-by-step? Can I apply the newly unposted invoice to the replcement checks which I haven't written yet? The manual and HELP keys are not clear. Thanks, again. Robin Ridinger
