Create Forecast Manually
Manual adjustments to forecast quantities are often made to reflect the experience of management in predicting future demand
Enables you to adjust and aggregate forecast
Guidelines for Creating Records Manually
Records are created for January through December, therefore limiting the forecast to a yearly forecast
You can create new records, or modify records from a CIM Load or the Run Forecast Simulation Calculation
Still must provide the forecast template criteria: ID, year, and items
Calculation is always method 00, since there is no forecast calculation performed against these records
You are creating the records by your own calculations, not the system’s calculation
Detail Forecast Maintenance
Cannot manually create a rolling forecast, only yearly
Simulated Forecast or CIM Data Load (36.15.1) generate the original forecast quantities
Run the calculation again to reproduce original forecast
The Adjusted Forecast quantity column is where you manually change the original results
Before modifying forecast detail records, archive the original forecast or copy to another forecast ID
Typically used to adjust decimal results from the calculation
Copying Forecast Results
Copying/combining typically used to:
Aggregate forecast for an item
Predict demand for new product
Apply multiplicative factors
Replace monthly forecast quantities, such as decimal production quantities
Multiplicative Factors
Single Item Simulation Copy (22.7.12) lets you scale forecast results for the new item as some percentage of the old item
Simulation to Simulation Copy (22.7.11) enables you to apply multipliers to the entire item range
Note: Scale cannot be negative.
Trend multipliers increase each month
You can use more than one multiplier at a time with a cumulative effect
Base increase/decrease is applied first, Scale second, Trend third
Factors are applied to source quantities and the results added to the target, not applied to combined source and target quantities
