PO price changes before the complete delivery
I have an issue..... we have ordered a certain material say 2000 pcs to be delivered over 6 months of time in a PO. The price at the tme of PO date was say 100 INR....now we have GRNd 200 pcs. After 1 month the vendor will charge 105 INR for the same item. Case is price changes keep happening like this almost every month. How to address this issue in PO...?
