We have not entered any Freight charges in PO by mistake, And for that PO, already we have done GR also. Now how can add the freight charges to that PO ? Now the freight charge condn type in PO became as Grey.Can make it as editable after GR also ? If i did so, what will happen ? If that is not the right way, then what is the other way. I want to add this freight charges to material cost.
