The processOrder pipeline chain submits the given Order for checkout. The processOrder pipeline chain is executed by the processOrder() method in the OrderManager. The processOrder() method adds the given Order, Profile, Request, Locale, and OrderManager to its parameter list, which is supplied to the executing chain. The pipeline chain’s transaction mode is TX_REQUIRED.
The following list describes each processor in the pipeline chain:
1.PipelineLink Name: executeValidateForCheckoutChain
This processor causes the validateForCheckout chain to be executed. If the execution of this chain causes any errors, then execution will be returned to the caller.
Transactional mode: TX_MANDATORY
Nucleus component: /atg/commerce/order/processor/ExecuteValidateForCheckoutChain
PipelineProcessor object: atg.commerce.order.processor.ProcExecuteChain
Transitions: In ATG Consumer Commerce, return value of 1 executes checkForExpiredPromotions next. In ATG Business Commerce, return value of 1 executes executeApproveOrderChain next.
2.PipelineLink Name: executeValidateForCheckoutChain
This processor causes the validateForCheckout chain to be executed. If the execution of this chain causes any errors, then execution will be returned to the caller.
Transactional mode: TX_MANDATORY
Nucleus component: /atg/commerce/order/processor/ExecuteValidateForCheckoutChain
PipelineProcessor object: atg.commerce.order.processor.ProcExecuteChain
Transitions: In ATG Consumer Commerce, return value of 1 executes checkForExpiredPromotions next. In ATG Business Commerce, return value of 1 executes executeApproveOrderChain next.
3.(ATG Business Commerce only)
PipelineLink Name: stopChainIfOrderRequiresApproval
This processor checks whether the order has been determined to require approval. Specifically, it checks whether the state of the order is PENDING_APPROVAL. If it isn’t, the order moves to the next processor in processOrder. If it is, execution of the processOrder chain stops.
Transactional mode: TX_MANDATORY
Nucleus component:
/atg/commerce/approval/processor/StopChainIfOrderRequiresApproval
PipelineProcessor object:
atg.commerce.order.processor.ProcCheckOrderState
Transitions: Return value of 1 executes executeValidatePostApprovalChain next. Return value of 2 executes executeValidateNoApprovalChain.
4.(ATG Business Commerce only)
Pipeline Link Name: executeValidatePostApprovalChain
If the order requires approval and has been approved, this processor revalidates order information in case the approver changed anything.
Transactional mode: TX_MANDATORY
Nucleus component:
atg/commerce/order/processor/ExecuteValidatePostApprovalChain
PipelineProcessor object:
atg.commerce.order.processor.ProcExecuteChain
Transitions: Return value of 1 executes checkForExpiredPromotions next.
5.(ATG Business Commerce only)
Pipeline Link Name: executeValidateNoApprovalChain
If the order does not require approval, finish validation.
Transactional mode: TX_MANDATORY
Nucleus component:
atg/commerce/order/processor/ExecuteValidateNoApprovalChain
PipelineProcessor object:
atg.commerce.order.processor.ProcExecuteChain
Transitions: Return value of 1 executes checkForExpiredPromotions.
6.PipelineLink Name: checkForExpiredPromotions
This processor walks through all the promotions that are being applied to the Order and verifies that none of them have expired.
Transactional mode: TX_MANDATORY
Nucleus component: /atg/commerce/order/processor/CheckForExpiredPromotions
PipelineProcessor object: atg.commerce.order.processor.ProcCheckForExpiredPromotions
Transitions: return value of 1 will execute removeEmptyShippingGroups next
7.PipelineLink Name: removeEmptyShippingGroups
This processor checks to see if there are any empty ShippingGroups in the Order. It removes any empty groups it finds. An empty ShippingGroup contains no Relationships. If the Order contains only one ShippingGroup then it will not be removed if it is empty.
Transactional mode: TX_MANDATORY
Nucleus component: /atg/commerce/order/processor/RemoveEmptyShippingGroups
PipelineProcessor object: atg.commerce.order.processor.ProcRemoveEmptyShippingGroups
Transitions: return value of 1 will execute removeEmptyPaymentGroups next
8.PipelineLink Name: removeEmptyPaymentGroups
This processor checks to see if there are any empty PaymentGroups in the Order. If so then it will remove them. An empty PaymentGroup contains no Relationships. If the Order contains only one PaymentGroup then it will not be removed if it is empty.
Transactional mode: TX_MANDATORY
Nucleus component: /atg/commerce/order/processor/RemoveEmptyPaymentGroups
PipelineProcessor object: atg.commerce.order.processor.ProcRemoveEmptyPaymentGroups
Transitions: return value of 1 will execute createImplicitRelationships next
9.PipelineLink Name: createImplicitRelationships
This processor adds Relationships to the Order if there is only one ShippingGroup or one PaymentGroup. If either one of these or both have no Relationships, then relationships will automatically be created. For the ShippingGroup, Relationships will be created between it and each CommerceItem. For the PaymentGroup, a Relationship will be created between itself and the Order with type OrderAmountRemaining.
Transactional mode: TX_MANDATORY
Nucleus component: /atg/commerce/order/processor/CreateImplicitRelationships
PipelineProcessor object: atg.commerce.order.processor.ProcCreateImplicitRelationships
Transitions: return value of 1 will execute setPaymentGroupAmount next
10.PipelineLink Name: setPaymentGroupAmount
This processor sets the amount property of each PaymentGroup in the Order based on the Relationships in each PaymentGroup. This amount is the amount that will ultimately be debited by the PaymentManager.
Transactional mode: TX_MANDATORY
Nucleus component: /atg/commerce/order/processor/SetPaymentGroupAmount
PipelineProcessor object: atg.commerce.order.processor.ProcSetPaymentGroupAmount
Transitions: return value of 1 will execute moveUsedPromotions next
11.PipelineLink Name: moveUsedPromotions
This processor updates the promotion use information in the Profile repository for the user.
Transactional mode: TX_MANDATORY
Nucleus component: /atg/commerce/order/processor/MoveUsedPromotions
PipelineProcessor object: atg.commerce.order.processor.ProcMoveUsedPromotions
Transitions: return value of 1 will execute authorizePayment next
12.PipelineLink Name: authorizePayment
This processor authorizes all the payment information in the PaymentGroups. It essentially calls the authorize() method in the PaymentManager for each PaymentGroup.
Transactional mode: TX_MANDATORY
Nucleus component: /atg/commerce/order/processor/AuthorizePayment
PipelineProcessor object: atg.commerce.order.processor.ProcAuthorizePayment
Transitions: return value of 1 will execute updateGiftRepository next
13.PipelineLink Name: updateGiftRepository
This processor updates the gift list repository information for the user.
Transactional mode: TX_MANDATORY
Nucleus component: /atg/commerce/order/processor/UpdateGiftRepository
PipelineProcessor object: atg.commerce.order.processor.ProcUpdateGiftRepository
Transitions: return value of 1 will execute sendGiftPurchasedMessage next
14.PipelineLink Name: sendGiftPurchasedMessage
This processor sends a gift purchased message to the messaging system.
Transactional mode: TX_MANDATORY
Nucleus component: /atg/commerce/order/processor/SendGiftPurchasedMessage
PipelineProcessor object: atg.commerce.order.processor.ProcSendGiftPurchasedMessage
Transitions: return value of 1 will execute addOrderToRepository next
15.PipelineLink Name: addOrderToRepository
This processor saves the Order to the Order Repository and if the user is not a registered user, adds the Order to the repository and then saves it.
Transactional mode: TX_MANDATORY
Nucleus component: /atg/commerce/order/processor/AddOrderToRepository
PipelineProcessor object: atg.commerce.order.processor.ProcAddOrderToRepository
Transitions: return value of 1 will execute sendPromotionUsedMessage next
16.PipelineLink Name: sendPromotionUsedMessage
This processor sends a message to the Scenario Server for each promotion that was used in the Order signifying that the given promotion was used by the user.
Transactional mode: TX_MANDATORY
Nucleus component: /atg/commerce/order/processor/SendPromotionUsedMessage
PipelineProcessor object: atg.commerce.order.processor.ProcSendPromotionUsedMessage
Transitions: return value of 1 will execute sendFulfillmentMessage next
17.PipelineLink Name: sendFulfillmentMessage
This processor sends a message to the fulfillment engine signifying that it should begin processing the Order.
Transactional mode: TX_MANDATORY
Nucleus component: /atg/commerce/order/processor/SendFulfillmentMessage
PipelineProcessor object: atg.commerce.order.processor.ProcSendFulfillmentMessage
