Calculate MS Level 1

Explanation

This activity is used to calculate MS level 1. 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. You can also choose to calculate level 1 for a single part. 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.
• While the calculation is underway, an on-hand analysis is made. You can view it in the Calculated Balance field in the MS Level 1 Part window.
• The physical quantity on hand is updated during calculation. This value is used for calculating quantity on hand development and 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.
