ASCP - how to implement changes in simulation plan into original plan

Hi,

I seek a solution for my issue with alternate plans. In the current setting we have a MPS plan used as a demand schedule in few other MRP plans. There is a need to copy the MPS plan and modify the planned order schedule on the copy and compare both plans in APCC. If we'll decide that the alternate plan looks better than the original one, we want to copy or somehow update the supply schedule from the alternate plan into the original plan.

Do you know any standard way of how to do this? We don't have Rapid Planning.
