A company must be able to inform their customers of order delivery dates. The Order Promising Lines page enables you to do this from a sales order line.
Based on an item’s known and expected availability dates, Business Central instantly calculates shipment and delivery dates, which can then be promised to the customer.
If you specify a requested delivery date on a sales order line, then that date is used as the starting point for the following calculations:
If the items are available to pick on the shipment date, then the sales process can continue. If the items are not available to be picked on the shipment date, then a stock-out warning is displayed.
If you do not specify a requested delivery date on a sales order line, or if the requested delivery date cannot be met, then the earliest date on which that the items are available is calculated. That date is then entered in the Shipment Date field on the line, and the date on which you plan to ship the items as well as the date on which they will be delivered to the customer are calculated using the following calculations:
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) 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 (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.
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.
When Business Central calculates the customer’s delivery date, it performs two tasks:
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:
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:
The shipment date is used to make the availability check. If the item is available on this date, Business Central confirms that therequested/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.
In addition to the external order promising that you can perform on the Order Promising Lines page, you can also promise internal or external delivery dates for bill-of-material items. For more information, see View the Availability of Items.
icon, enter Order Promising Setup, and then choose the related link. Enter a number and time unit code in the Offset(Time) field. Select one of the following codes.
| Code | Description |
|---|---|
| d | Calendar day |
| w | Week |
| m | Month |
| q | Quarter |
| y | Year |
For example, "3w" indicates that the offset time is three weeks. To indicate the current period, prefix to any of these codes with the letter “c”. For example, if you want the offset time to be the current month, enter cm.
If you want to include warehouse handling time in the order promising calculation on the purchase line, you can set it up as a default for the inventory and for your location.
icon, enter Inventory Setup, and then choose the related link. If you have filled in the Inbound Whse. Handling Time field on the Location Card for your location this field is used as the default inbound warehouse handling time.
icon, enter Location, and then choose the related link. If you leave the Inbound Whse. Handling Time field blank, then the calculation uses the value in the Inventory Setup page.
If you want to set up an outbound warehouse handling time to be included in the order promising calculation on the sales line, you can set this up as a default for the inventory.
icon, enter Inventory Setup, and then choose the related link. If you have filled in the Outbound Whse. Handling Time field on the Location card for your location, this field is used as the default outbound warehouse handling time.
icon, enter Locations, and then choose the related link. If you leave the Outbound Whse. Handling Time field blank, then the calculation uses the value in the Inventory Setup page.
Before an item can be included in the order promising calculation, it must be marked as critical. This setup ensures that non-critical items do not cause irrelevant order promising calculations.
