For a particular actual scanario that has been initialized, we have a plan item which has a sales order of 200 pcs existing. When i put a forecast of 300 for that period and run the item master plan it is expected that it should create a production plan for 300-200=100 qty. However it does not create a production plan. in the plan items session (Master Plan tab), the Production pan is set to 'Always update'.
Is there any additional setting for the production plan to be updated?
