Activating, Modifying, and Deactivating Loyalty Promotions
You control whether a promotion applies to transactions by Activating or Deactivating it. A promotion only applies to a transaction if the transaction's transaction Date is with the promotion's start and end date period, and the promotion is active.
Note: Keep a promotion active as long as it applies to a transaction, even
if it is past the promotion's end date. For example, if the business
rule is that members can submit transactions for up to six months after
the transaction's date, then all promotions must remain active for six
months after the promotion's end date.
