The error is occurred from IR recording via PO(purchase order) by 3S that we have found it when reconcile GR/IR accounts by grouping open items these accounts in each PO and analyse pending amount then go to see details in PO if we find any doubt.
Anyway, I think it should be reviewed by 3S/AP and I had discussed already with Khun Pavares to do that and he asked us support how to check.
