CO order and price history record in F4074

Hi,

We are on E1 9.0. We are doing Credit Order ( Type CO) and wanted to have price history record in table F4074 while changing the Unit Price in order. We are not creating CO order from history. Can anyone guide me how to achieve this? At present, we don't see any price history record in table F4074 after change the price.

We are using advance warehousing.

Thanks in advance.
