Use this to copy one entire master schedule level 1 set to another master schedule set for later comparison or
for simulation purposes. For example, if master schedules are planned at the beginning of a planning period and
wants to have it after certain period of time for comparisons to check the deviations from the actual plan, this
can be used to copy your initial master schedule plan to a different master schedule set and use it for later
comparisons as mentioned earlier. You can keep many number of such sets of your plan from different time instances
and can use for comparisons as well.
Note: Copy Entire Master Schedule and Copy Forecast differs from each other. Copy Forecast, copy
only the forecast on a selected set to another while Copy Entire Master Schedule, copy the whole schedule including
forecasts, master production schedule, customer dimensions and supply allocation values.
To perform this activity, a master production schedule set must be created.
As a result of this activity, the entire level 1 master production schedule is copied to the destination MS set. If there was a master production schedule already in the destination set, then it will be replaced.
