Manually Update Master Production Schedule Level 1

Explanation

This activity is used to manually update schedule receipts for the level 1 master production schedule. Plan Period Templates are used to display master production schedule quantities in a series of date periods. Only a fixed number of periods, the first 40, will be displayed.  A period template with a past due period cannot be used in master scheduling for multiple parts. If a period template with a past due period is selected, then a message will appear before attempting to query. The Period Template range and MS Set should be selected to group MS Level 1 data. 

In the Master Schedule for Multiple Parts page, only Level 1 Updated rows can be updated. The value in each period represents a sum of master production schedule receipts that is generated on every workday within the periods. When you save the changes, the new value will be evenly distributed  to each workday in the period.

The re-calculation of the current template details may be necessary if the current date does not match the begin date of the selected period range. 

Prerequisites

• This activity requires the existence of a Level 1 part that has an associated set of planned customer demands. 
• Master schedule level 1 parts must have been entered and the forecasts registered. 
• Master schedule calculation of level 1 must have been performed. 
• To update the available forecast and available actual values, at least one Level 1 Updated row that has been modified and not saved is required. 

System Effects

• When saving the modified level 1 updated values, the system will divide the value by the number of work days in the period and allocate it for each work day. 
• If level 1 forecast already exists on a work day, the existing master production schedule receipt value will be replaced and the status set to Fixed. 
• If a forecast line does not exist, a new level 1 forecast record is inserted with a fixed master production schedule receipt. When the value in the level 1 updated record is modified, the available forecast and available actual quantities are automatically updated.
• The available forecast and available actual rows are updated based on the level 1 updated row. The system will use the following formulae:

  Available Forecast = Previous period Available Forecast value - Customer Forecast - Actual Demand + Work In Process + Level 1 Updated
  Available Actual = Previous period Available Actual value - Actual Demand + Work In Process + Level 1 Updated
  
  Note: For the first period the Previous period value = Qty On Hand.
