2641874 - Sales Order Missing in Supply Planning 'Product Planning Details'

You have created a Sales Order XYZ  (XYZ represents the Sales Order ID) for a Product PPP (PPP represents the Product ID) which you currently do not have in your Warehouse, and have released the Sales Order to Logisitics Execution by forcing Confirmation, but when you go to the Supply Planning Work Center, and open the Product Planning Details view, you cannot find the Sales Order XYZ. As a result, the Customer Demand is not considered during a Planning Run, and hence no Proposal is created.
