grni write offs

 Hi
I'm having trouble reconciling the ap po accrual recon report to the the balance of the grni in the general ledger. I have a question about the amount column on the ap po accrual recon report. on the previous periods report the amount was showing in the amount column. a write off was then processed in the next period and the amount coulmn in the ap po accrual recon report now shows as a positive number. is this correct

Thanks
Grant
