Allocate Supply in Source Promising

Create an allocation rule to manage real-time supply when you use source promising.

Preserve a fixed amount or a percent of supply for each customer, organization, region, demand class, or attribute according to your criteria.
Use the rule to prevent earlier orders from consuming all the supply that's available.
Specify a date range for shipments that you want Promising to include when it consumes the allocation. For example, to support a seasonal event, sales promotion, or other campaign.
Use this feature to help manage supply when you have thousands or even millions of item and organization combinations.

Try it:

Set the Check ATP attribute to Source Based Promising. See Set Up Your Items in Product Information Management.
Enable the Respect Allocation Constraints attribute in your ATP rule. See Set Attributes on Your Supply Chain Search.
Set up the allocation node that you want to use with this feature. See Allocate Supply in a Hierarchy.
Set up the allocation rule that you want to use to allocate the item that you're promising with this feature. See Allocation Rule.
Go to the Order Management work area, open your sales order, then use the Check Availability action to review supply allocations and availability results. For details, see Schedule Fulfillment Lines Manually.
