Wrong way to calculate MRP when exist Forecast
At the following link: http://www.adempiere.com/A_Step_by_Step_Guide_to_Libero_Manufacturing#Step_4:_Calculate_MRP
the manual show a teoretical error in MRP calculation when exist forecast: "MRP will summarize the demand from both Sales Order and Forecast and use the behavior of the Product (i.e., Is Sales or Is Purchase, etc.), Product Data Plan (i.e., Min Order Qty, Promised Delivery Time, Order Pack Qty, etc.), Bill of Material and Workflow Process, to determine the next action."
Forecast is usefull to create MO than must desapear. MO qty generated must be consumed by SO. At the moment in pp_mrp remain "FCT" lines that create DEMAND (D) and keep locked availability.
