Work Center Rates

Hi Team,

We are on 7.3 cum 10 version of JDE. We came across of issue where when we are running copy cost program to copy cost from one method to another within B/p, WC rates gets impacted. We are aware that in this version of JDE there is no B/p specific selection for rates so it updates rates for all work centers present in that library. But in our case either it wiped out the rates or simulated rates wiped out but frozen rates are visible.

Do we have any workaround if we can apply in this version which does not affect rates by either P30890 or P30835 program.
