DemandCaster is a highly relational system and as such the settings applied to an item defines the replenishment status of the item per the Basic Order Quantity and Replenishment Logic article. We also discuss the things to consider in Requirement Planning and Forecasting in the article General Recommendations and Considerations. If you see an item as a requiring an orders that should not be, it is likely a result of the following:

1. The item stock setting is wrong: You believe the item is make to order and the setting is make to stock. The solution is to either adjust the extraction query to ensure the correct setting is applied to the item during the upload if it in fact it is set properly in your ERP, change the setting in your ERP to the correct one if the setting is incorrect in your ERP, or change the setting in DemandCaster. When an item is set to make/order to stock, it will trigger an order if the net availability is less than the order point. The order point is forecast + safety stock over lead time.
2. There is an open customer order that is not actually open: In all cases this is a result of the query designed to pull open and closed sales orders from your system. In some instances the order is actually errantly open in your system. If so, closing the order will solve the problem. In other cases, the query needs to be modified to ensure the order does not flow through to DemandCaster as an open order.
3. A purchase or production order that is open is not showing up: Like the customer orders, in all cases this is a result of the query designed to pull open and closed purchase or production orders from your system. The query needs to be modified to ensure the order flows through to DemandCaster as an open order.
