PO update to info record without FRB1 condition

Scenario:

There is an info record for a vendor/material combination that is purchase org only (not plant specific).

A PO is create. A price for the material is pulled into the PO along with a FRB1 value. Where is it getting this information. There isn't a value for the material or the FRB1 record in the info record. Where does it pull this value?

Thanks!
