Updating Customer Pricing

Hi List,
I am trying to update customer prices using R42950, but with limited good results. I find the prices change but don't see the changes written to the Price History table (F4074). Also, if I have set the processing option to use current system date as the price effective date, but that does not update to the order. Are these outcomes normal or have I not set something correctly. Any hints/help is appreciated.

When you run the R42950 for a specific order did you check in the Price history through the order inquiry? You should see the price update on the original sales line unless your specify to update the changes to a a new sales order line in the processing options.
