BAPI for ISU Price Change

Hello,

I am struggling to find a BAPI to update price in EA90. I checked out Business Object PRICE. It has method, HISTORYCHANGE. I am able to update price amount for existing Valid from - To date using this method. But when I try to create a new record of price in History tab using this method, it does not create one.

Please help

Regards,

Viraj.
