Multiple Price in Purchase Order

Dear SAP Experts,

I wish to ask following question:

the client requirement is that to have multiple price options at the time of creation of PO. in standard SAP or development needed? If it is development please provide me some logic

Example :

Material_XX1 Qty= 1000 NOS Price= $10

Material_XX1 Qty= 1000 NOS Price= $12

in example same material, qty different / maybe same , price always different in same PO.

Regards,

Pal
