Order Promising

• Order promising helps you reliably promise delivery dates to your customers
• Order promising calculates earliest ship and receipt dates based on delivery date control method and transport days

Delivery Date Control Methods

• Sales lead time - based on default number of days, doesn't consider stock availability, known demand, or planned supply
• ATP (available-to-promise) - includes uncommitted inventory, lead times, planned receipts, and issues
• ATP + Issue margin - shipping date equals ATP date plus issue margin for the item
• CTP (capable-to-promise) - availability calculated through explosion, not allowed with Planning Optimization
• CTP for Planning Optimization - use CTP calculation provided by Planning Optimization

Updating Order Promising Information

• Order promising information is updated only if existing date can't be fulfilled
• If current date can't be met, order promising is triggered
• If current date can still be fulfilled, order promising isn't triggered and current date remains

ATP Calculations

• ATP quantity calculated using 'cumulative ATP with look-ahead' method
• ATP quantity includes uncommitted inventory balance in first period
• ATP quantity calculated for each period in which a receipt is scheduled
• ATP calculated based on formula ATP = ATP for previous period + Receipts for current period - Issues for current period - Net issue quantity for each future period
• ATP quantity always greater than or equal to 0
• Negative ATP quantity automatically set to 0

ATP Backward Demand and Supply

• ATP backward demand time fence controls how far back to look for delayed demand orders or inventory issues
• ATP backward supply time fence controls how far back to look for delayed supply orders or inventory receipts
• ATP delayed demand offset time and ATP delayed supply offset time control when delayed demand or supply considered
• Example: 7 entered in ATP backward demand and supply time fence fields, and 1 in ATP delayed demand and supply offset time fields

CTP Calculations

• CTP functionality provides realistic delivery dates based on existing inventory, production capacity, and transportation times.
• It considers availability of both materials and capacity, giving a more accurate picture of whether demand can be satisfied within a given time frame.

CTP for Planning Optimization

• CTP for Planning Optimization supports a subset of CTP scenarios available in the built-in engine.
• For detailed information on using CTP with each engine, refer to the 'Calculate sales order delivery dates using CTP' guide.

Delivery Alternatives

• Explore delivery alternatives to meet customer demands.
• Inventory visibility and on-hand change schedules can help determine the best option.
