Explain the process of calculating the planned activity output through Long term planning?

In Long term planning process the planned production quantities are
entered for the planning year in a particular scenario. The Long term
planning is executed for the scenario. This generates the planned activity
requirements taking the activity quantities from the routing and
multiplying with the planned production.


The activity requirements are then transferred to the controlling module
as scheduled activity quantities. Thereafter you execute a plan activity
reconciliation which will reconcile the schedule activity and the activity
you have planned manually. The reconciliation program updates the
scheduled activity quantity as the planned activity in the controlling
module.
