Re: Forecasting and MPS/MRP

The forecasting module is oriented toward monthly processing. Shipments from
sales analysis are passed to the forecasting module as a step in the
forecasting period end process (Transfer Last Period). This represents
demand experience over which the algorithms run yielding a forecast by
month. Via the spread profile defined in forecasting, the monthly forecast
number is broken into weekly buckets for the planning systems. This is
accomplished in the monthly transfer, typically done once per month.

If you need to update your forecast during the month, you can manually do
the change in the forecasting module and do the transfer to the planning
system again. Alternatively, the forecast can be maintained in the planning
systems. I'm not 100% sure but I think that subsequent transfers from the
forecasting module will step on forecasting changes done in the planning
systems.

The planning system did not used to recognize shipments and I don't think
that functionality was ever added. I know a couple of customers that did
this as a mod. So, if you have a large planning bucket close to your past
due bucket and a shipment was made early, shipments will consume inventory
without reducing the forecast. If the forecast in the planning bucket now
exceeds actual demand, demand will be overstated. By the way, this is also
why forecast consumption can give a misleading answer.
