For the cloud CRM to work seamlessly with SAP S/4HANA, both systems must exchange master data. Usually, SAP S/4HANA is already in place before starting the implementation of the cloud CRM. As a result, SAP S/4HANA is typically seen as the primary system from which master data needs to be initially loaded.
Some business objects can be edited in the cloud CRM and sent back to SAP S/4HANA, such as account and contact master data. These objects can be replicated bi-directionally. Other business objects may only be edited in one of the systems (the leading system for the respective scenario) and may only be replicated in one direction: unidirectionally. Product categories and product master data are typical examples of unidirectional replication from SAP S/4HANA to the cloud CRM.
The following graphic provides an overview of some of the most important master data business objects that can be replicated between SAP S/4HANA and the cloud CRM. For the latest supported master data integration scenarios, please refer to the SAP Business Accelerator Hub.
