Hello,
If I am following your question you are looking for a function that looks at Order Promising. In BC, on the Sales Order List or when a Sales Order is open, you can click to Actions/Functions/Order Promising. Here you can use the tools Available-to-Promise or Capable-to-Promise.
Some information on these tools...
The Order Promising functionality enables you to promise an order to be shipped or delivered on a specific date. The date that an item is available to promise or capable to promise is calculated, and order lines are created for those dates that you accept. The functionality calculates the earliest possible date that an item is available for shipment or delivery. It also creates requisition lines, in case the items must first be purchases, for those dates that you accept.
Business Central uses two fundamental concepts:
- Available to Promise (ATP)
- Capable to Promise (CTP)
Available to Promise
Available to promise (ATP) calculates dates based on the reservation system. It performs an availability check of the unreserved quantities in inventory with regard to planned production, purchases, transfers, and sales returns. Based on this information, Business Central automatically calculates the delivery date of the customer’s order because the items are available, either in inventory or on planned receipts.
Capable to Promise
Capable to promise (CTP) assumes a “what if” scenario, which only applies to item quantities that are not in inventory or on scheduled orders. Based on this scenario, Business Central calculates the earliest date that the item can be available if it is to be produced, purchased, or transferred.
Example
If there is an order for 10 pieces, and 6 pieces are available in inventory or on scheduled orders, then the Capable-to-Promise calculation will be based on 4 pieces.
Calculations
When Business Central calculates the customer’s delivery date, it performs two tasks:
- Calculates the earliest delivery date when the customer has not requested a specific delivery date.
- Verifies if the delivery date requested by the customer or promised to the customer is realistic.
If the customer does not request a specific delivery date, the shipment date is set to equal the work date, and availability is then based on that date. If the item is in inventory, Business Central calculates forward in time to determine when the order can be delivered. This is accomplished by the following formulas:
- Shipment Date + Outbound Warehouse Handling Time = Planned Shipment Date
- Planned Shipment Date + Shipping Time = Planned Delivery Date
Business Central then verifies if the calculated delivery date is realistic by calculating backward in time to determine when the item must be available to meet the promised date. This is accomplished by the following formulas:
- Planned Delivery Date - Shipping Time = Planned Shipment Date
- Planned Shipment Date - Outbound Warehouse Handling = Shipment Date
The shipment date is used to make the availability check. If the item is available on this date, Business Central confirms that the requested/promised delivery can be met by setting the planned delivery date to equal the requested/promised delivery date. If the item is unavailable, it returns a blank date and the order processor can then use the CTP functionality.
Based on new dates and times, all related dates are calculated according to the formulas listed earlier in this section. The CTP calculation takes longer but it gives an accurate date when the customer can expect to have the item delivered. The dates that are calculated from CTP are presented in the Planned Delivery Date and Earliest Shipment Date fields on the Order Promising Lines page.
The order processor finishes the CTP process by accepting the dates. This means that a planning line and a reservation entry are created for the item before the calculated dates to ensure that the order is fulfilled.
You setup Order Promising on the Order Promising Setup page.
Hope this helps.
Thanks,
Steve
