Calculate MS Level 1 for Single Part
Explanation
This activity is used to calculate MS level 1 for a single part. This calculates forecast and actual demand,
traces orders, and provides action proposals. The master production schedule is calculated and created from
forecasts on level 0, the forecast you enter on level 1, and the actual backlog of orders. This gives you quick
access to the results of the forecasts you entered.
Prerequisites
To perform this activity, you must have entered master schedule level 1 parts and registered forecasts. The
registration of level 1 parts can be handled manually or automatically from the level 0 calculation.
System Effects
- The system's calculation suggests new orders and actions for existing orders.
- MS results in a gross demand, which forms the basis of MRP.
- At the start of each calculation, period 1 is updated. This means that the system considers the run date. If
the program was run on Tuesday and the period used is a five-day week that includes Friday, then period 1 will be
from Tuesday to Friday. If the program is run on Wednesday, period 1 is from Wednesday to Friday.
- The projected quantity of the part on-hand is analyzed and displayed in the Projected Balance field in
the Master Schedule by Part/Master Schedule Grid tab. The quantity on-hand is
also updated. This value is used to calculate the development of quantity on-hand and the quantity available to
promise.
Note: In the master schedule Level 1 calculation, manufactured/acquired split, supplier split ,standard
multiple quantity and lot sizes will be considered.
