Note to Supplier/receiver does not pick information from requisition

Summary:

Hello,

We had populated Note to Supplier and Note to Receiver on the Blanket Purchase Agreement (BPA), while we create a requisition referencing BPA and enter different (Not the same information populated on BPA) data populated on Note to Supplier and Note to Receiver.

We understand, that information populated on Note to Supplier and Note to Receiver on requisition should be available on the Purchase Order. However, we see that Oracle picks the information from BPA itself, even in the case, where Note to Supplier and Note to Receiver are blank on BPA.

We desire and believe, that data on BPA shall be picked only in the case, if there is no information passed to Note to Supplier and Note to Receiver on the requisition. Can you please suggest here.
