Hi,
If you are creating PO without reference, please check whether info record has been updated correctly from the quotation. If not updated, please check whether the condition type PB00 / PBXX is maintained as "manual" condition in the corresponding pricing procedure. In this case, the condition wont be copied from quotation to info record. The note : 13127 - Update in info record from PO, quotation, contract explains the update logic.
If you are creating PO with reference to quotation, then the condition will be copied from quotation. You may refer the note: 456691 - FAQ: Price determination in purchasing Q num 25. Also check the "manual" indicator in pricing procedure for PB00 condition.
Regards,
