To create a new stacking rule:
On the Marketing tab, click Stacking Rules.
Click the New Rule button to display the details page for the rule.
Enter a name for the new rule.
Specify promotions to add to the rule.
Click Edit and select promotions to add to the rule. You can filter the list by typing or pasting some text in the Promotions box.
The filter control matches letters or numbers that you type, wherever they appear in the name or ID, not just at the beginning. Usually, as you type more characters, there are fewer matches. When you see the item you want, select it.
Click Add Selected.
Click Done when you finish adding promotions to the rule.
Specify the maximum number of promotions that can be applied to an order from this rule. The default value is Unlimited.
If you specify a maximum number of promotions, Oracle Commerce Cloud Service evaluates the rule’s promotions in order, based on their priority. See Understand promotions for more information about promotion priority.
Click the Create button at the bottom of the Details pane.
