While trying to create to create a invoice verification (I.e. MIRO) with reference to a PO with one line item. Immediately hit enter key but the "AMOUNT" and "QUANTITY" fields of this ine item shown in the MIRO screen is grey out and non-editable.
May I know why the system grey out this line item doesn't allow me to change the quantity and amount?
FYI, this PO line item is created using order quantity of 66 and partial GR with quantity of 26 for 2 times but when I want invoice with quantity of 26, at this time the two fields are grey out and un-editable
