Replicating Subscription Contracts using SAP Event Mesh

1. Register Inbound Event Customer

   In the V_INBCONSUMR view, register the inbound event consumer.

2. Perform Inbound Mapping

   In the V_INBOUNDMAP view, perform inbound mapping.

   Specify the following:

   Field	Value
   Consumer ID	e.g., EntitlementManagementSystem
   Topics	e.g., entitlement.provisioned.v1
   Inbound Payload Structure	e.g., CRMS4S_EMS_ENTITLEMENT_EVT_PRV
   Internal Event Class	e.g., CL_CRMS4_EMS_ENTITLEMENT_WF

   ​

3. Configure XBE (/IWXBE/CONFIG)

   1. Activate the channels to establish a connection to enterprise messaging and listen to events.

   2. Configure inbound bindings and subscriptions.

   3. Set up the subscription for the topic.

1. Map Event Types

   Use value mapping to map SAP S/4HANA standard activated event types to SAP Entitlement Management business event types.

2. Map Change Processes

   Map SAP S/4HANA standard change processes to your own customized change processes if necessary.

1. Configure the Sender tab as follows:

   1. Set the Sender Adapter Type to AMQP.
   2. Specify the Host, Port, and Path of the SAP Event Mesh service key.
   3. Set the Authentication Method to OAuth2 Client Credentials and provide the Credential Name.

2. Configure the Receiver tab for SAP S/4HANA as follows:

   1. Set the Receiver Adapter Type to HCIOData.
   2. Provide the address of the SAP S/4HANA OData service for subscription contracts.
   3. Set the Proxy Type to On-Premise.
   4. Specify the Location ID, Authentication Method, and Credential Name.​

3. Configure the Receiver tab for SAP Entitlement Management as follows:

   1. Set the Receiver Adapter Type to HTTP.
   2. Provide the EMS Entitlement Query v2 API URL.
   3. Set the Authentication Method to OAuth2 Client Credentials and provide the Credential Name.​

4. On the More tab, configure the Extension Handler Address as follows:

   1. Set the Receiver Adapter Type to ProcessDirect.
   2. For the Extension Integration Flow Entry Point, specify the address: /EMS/ReplicateSubscriptionContractViaEvent_PostExit

5. On the More tab, set the Extension Implemented field to true to extend the standard integration flow.

6. On the More tab, maintain the following fields with values from SAP S/4HANA:

   • Customer System
   • Offering System
   • Source System

7. On the More tab, configure the Entitlement Attribute for Lock/Unlock field.

   Note

   This is required for a Lock/Unlock scenario.

1. Create Rule Set for Parent Items

   Define conditions and tasks for creating or updating entitlements.

2. Create Rule Set for Child Items

   1. Establish relationships under the parent item.

   2. Implement the necessary script to handle the creation and update of child entitlements.

This integration flow facilitates the replication of subscription contracts from SAP S/4HANA to SAP Entitlement Management using SAP Event Mesh. It ensures that subscription contract data, including state changes and other relevant details, is accurately synchronized to SAP Entitlement Management in a timely fashion.

1. The process begins with configuring settings in SAP S/4HANA Subscription Order Management (SOM), where inbound event consumers are registered and event mappings are established.
2. SAP Cloud Integration is then configured to handle the replication, with specific attention to sender and receiver settings, ensuring secure and efficient data transmission.

3. In SAP Entitlement Management, corresponding settings are created to receive and process the subscription contract data.

   This involves defining communication channels and configuring entitlement generation rules.

The integration supports various event types, such as contract creation and state changes, and allows for customization through value mapping.

By following these steps, businesses can maintain accurate and up-to-date subscription contract information in SAP Entitlement Management, ensuring alignment between subscription contracts and entitlements.
