Dear,
I have the case below, due to the incorrect amount posted for the IR, so the GR amount getting incorrect amount.
basically the steps as below;
1. Incorrect IR amount posted
2. GR posted and amount is followed the IR amount
3. Reverse IR and repost a correct one
4. reverse GR.
now the issue that the step 4 has successfully reversed the GR qty but the GR amount still having balance as shown in the screenshot below;

Can any one please advise me the step to balance this PO GR and IR amount in the PO history? and how this is happen?
