Scenario: A salesperson is on a call with a customer who wants to order 1,000 items. The customer wants to know when he can receive them. The salesperson can see 200 in stock, but must be able to quickly tell the customer when to expect the other 800.
Useful for: distribution companies who purchase large quantities of items (often from overseas) with long lead times.
Include manufacturing lead times for manufacturing companies
Include work calendars, so holidays are properly tracked
External systems (such as a commerce system) should be able to get this information
Quantity to promise should be available from a sales order or as a stand alone report (perhaps in calendar format)
