Incorporating approved change into the Performance Measurement Baseline (PMB) using P6v7

I have used the 'maintain Baselines' function to update a copy of the project contract baseline in order to demonstrate slippage in the current schedule when introducing an approved change.

this has not resulted in the transfer of the 'coded up & filtered' activities being copied into the PMB from the current schedule as i had expected. therefore i can't show the slippage using this process.

can anyone suggest an alternative method ??

i have now unlinked the copied PMB from the current schedule and restored it in order to try another process.

thanks
