PMWeb Production records track the completion of work units. You can use that information to update your Forecast. If you click the Production button, the Production dialog opens. If you select a Production record and then click Save & Exit, the dialog closes and the data from the Production record is transferred into the Forecast lines.
Cost Codes in Production are used to match lines in the Forecast
Current Quantity from Production updates the Quantity Completed field in the Forecast
% Complete is recalculated for you as (Quantity Completed/Quantity To Complete) times 100
