ePro Requisition- Item Order Qty multiple

Hi,

I am creating an ePro Requisition for an item which has Order Qty multiple defined as 5 at Purchasing Attributes > Item Vendor UOM

But the system still allows me to enter requisition for that item with order qty of 12. It should not have allowed since the Order qty multiple has been defined as 5 . 

I was hoping that system would give me a warning or error message saying that you can order this item only in multiples of 5.

Is there a way I can restrict the Order qty on Requisition based on the Order multiples defined on Purchasing item attributes > Item Vendor UOM?
