How to cahgne price adjustment sechdule

Hello,

We are using JDE 9.1.4 , we use advance pricing in sales order &  attached price adjustment schedule at sales order level , we have scenario where we need to revise the price adjustment schedule for open orders  , can you brief me how it can be possible.

I have try to attach the schedule but the amount is not reflected in Table F4074 -Against BP0R filed where it should be with basic amount.

Thanks,

Mayank
