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