Delivery Date Calculation Logic


How does the system calculate the promise date on a sales order line?

Glossary of Terms



Where to Edit this item


Available to Promise - The date the item is promised to ship.

 This is auto-calculated by the software based on existing quantity on-hand, quantity allocated, and (if appropriate) Lead Time for manufactured items (setup on Item Edit | Logistics | Manufacturing.) 



Edit Item | Locations


Parts needed to make/produce the product

Item Setup | purchased/Manufactured: - Select Manufactured

Manufacturing Method: Choose Order Entry, Production floor, shop floor

Cutoff Time

The time the mail goes out at a specific location.



Estimated Delivery Date

The date the item is expected to be delivered to final destination.

Inbound Purchase Orders

For purchased items, an inbound purchase order is proof of when the item will be available to the client. For example, if an item has a 30-day lead time, and a purchase order states it is 40 days out, the purchase order date available is the date to promise. The reason is based upon the assumption that communications have taken place between purchaser and supplier, and that is the quickest the items will be available.
