What's New


Issue Key	Release Notes	Note
PPCE-8044	Transaction-related non-monetary benefit proration improved The virtual discount and loyalty points share proration of transaction-related promotions have been improved. Non-monetary discount: previously, if the adjustment amount to be assigned to the last item was found to be invalid by the validation logic, then the proration failed all together. After the adjustments, the remaining amount is assigned to the rest of the proration items. Loyalty points: If the total benefit is not exactly distributed among the proration items, the applied correction is also rounded by the points share rounding rule. If the applied correction is invalidated on the last item by the validation logic, it is assigned to the rest of the proration items. If, for some reason (e.g. due to rounding), an item in the proration list does not receive a bonus points share, it will receive zero bonus points share if this is allowed in the configuration. If all virtual discount or loyalty points shares are considered invalid, the corresponding promotion is not applied. As a result, expectations for the following JBehave stories had to be corrected: cha_incentive_points_19.story
PPCE-8006	Compatibility with Spring 6.1.x and SpringBoot 3.3.x From now on, PCE is compatible with Spring 6.1.x and SpringBoot 3.3.x. Minor compatibility issues have been fixed.
PPCE-7935	Improved transaction-related promotion rounding calculation The calculation of the discount share rounding amounts for transaction-related promotion price derivation rules has been corrected. The rounding amount is the difference between the calculated, unrounded discount share and the finally assigned, rounded discount share value. In case the total discount amount cannot be assigned to the line items (due to rounding or invalid discount shares), the remaining unassigned amount is added to the rounding amount of the last item(s).
PPCE-7889	Accept the TriggerSequenceAddend for externally applied manual promotions The TriggerSequenceAddend is now considered for externally applied manual promotions. This means that the next promotion that could be applied internally must have a sequence that is greater than the sum of the sequences from an externally applied promotion and the TriggerSequenceAddend.
PPCE-7863	Transaction-related discount proration improved The discount share proration of transaction-related monetary discounts has been improved. Previously, if the adjustment amount to be assigned to the last item was found to be invalid by the validation logic, then the proration failed all together. After the adjustments, the remaining amount is assigned to the rest of the proration items or if it not possible for a remaining amount to be assigned to any item, it will be accounted for in the shared rounding amount.
PPCE-7765	Change logging level to WARNING in case an invalid value is to be used for a system parameter but default value is used instead Logging level has been changed from ERROR to WARNING in case an invalid value is to be used for the system parameter but the default value is used instead. Unified logging in case null value was used. Redundant logging has been removed.
PPCE-7751	Unify validation algorithm for points and discounts Unified the validation algorithm for points and discounts for the line item-related total price modification methods.

Resolved Issues


Issue Key	Release Notes	Note
PPCE-7965	Triggering line items without benefit do not get modifier references when the total price modification method is used As long as the promotion is successfully applied, all triggering items get a modifier reference, even if they do not get any benefit due to price increase, zero discounts or for any other reason.
PPCE-7952	M&M does not grant zero virtual discount when allowZeroRebate is set to false Zero virtual discount (virtual discount types are: GIFT_CERTIFICATE("01"), TENDER("02"), COUPON("04"), MANUFACTURER_COUPON_TENDER("99")) must always be applied regardless of the rule type and allowZeroRebate flag state. This bug has been fixed.
PPCE-7948	Exception when deserializing an unknown eligibility during recommendation The GK-specific object mapper has been configured so that it does not fail when an unknown eligibility type is loaded during a recommendation process.
PPCE-7923	NPE during validation of an unknown eligibility type for recommendation when TRACE log level is active During validation of an eligibility with an unknown eligibility type for recommendation, the PCE could throw a null pointer exception when a TRACE log level was active. This bug has been fixed.
PPCE-7855	ExclusiveConditionDiscountablePositionHandler performance issue A bug that caused significant performance degradation when a transaction-related promotion was applied on top of a line item-related promotion has been fixed. In addition, the ExclusiveConditionDiscountablePositionHandler also considers FrequentShopperPointsModifiers and externally applied modifiers from now on.
PPCE-7811	RPM for applied transaction-related promotion is missing in the transaction If a single transaction-related manual promotion was applied multiple times due to several manual triggers registered in a transaction with different trigger sequence numbers, and if that manual promotion conflicted with some other promotion(s) and the Brute Force conflict resolution algorithm was used to resolve the conflicts, then some retail price modifiers or frequent shopper points modifiers for successfully applied promotions might be missing in the result transaction. This bug has been fixed.
PPCE-7730	Zero transaction-related points validation Bonus points validation for transaction-related promotions was unified with discount validation. A bug that prevented the creation of a zero frequent points modifier when it was allowed has been fixed. LineItemRebateValidators and RebateValidators are now called after the discount share is calculated.
