How to Connect and Transfer Data from SAP C/4HANA to SAP BW/4HANA

SAP C/4HANA is a suite of cloud-based customer experience solutions that help businesses engage and retain customers across different channels and touchpoints. SAP BW/4HANA is a data warehouse solution that enables fast and flexible analysis of large volumes of data from various sources. In this blog post, we will explore how to connect and transfer data from SAP C/4HANA to SAP BW/4HANA using DataSources.

What are DataSources?

DataSources are objects that define the structure and properties of the data that can be extracted from a source system and loaded into SAP BW/4HANA. DataSources can be used for different types of data, such as transactional data, master data, text data, hierarchy data, etc. DataSources can also be used for different extraction methods, such as full extraction, delta extraction, real-time extraction, etc.

From a technical perspective, the DataSource is a set of logically-related fields that are provided for access and transfer data into SAP BW∕4HANA in a flat structure (the extraction structure) or in multiple flat structures (for hierarchies). DataSources supply the metadata description of source data.

How to Connect SAP C/4HANA to SAP BW/4HANA?

To connect SAP C/4HANA to SAP BW/4HANA, you need to create a connection between the two systems using the SAP Cloud Platform Integration (CPI) service. CPI is a cloud-based integration platform that allows you to connect different applications and systems in a secure and reliable way. CPI provides various adapters and connectors that enable you to integrate with different protocols and formats.

To create a connection between SAP C/4HANA and SAP BW/4HANA, you need to follow these steps:

  • Log in to the CPI cockpit and create an integration package.
  • In the integration package, create an integration flow that defines the source system (SAP C/4HANA), the target system (SAP BW/4HANA), the message mapping, the routing rules, and the error handling.
  • In the integration flow, configure the source system connection by selecting the appropriate adapter and connector for SAP C/4HANA. For example, you can use the OData adapter and connector to access the OData services exposed by SAP C/4HANA.
  • In the integration flow, configure the target system connection by selecting the appropriate adapter and connector for SAP BW/4HANA. For example, you can use the SOAP adapter and connector to access the web services provided by SAP BW/4HANA.
  • In the integration flow, configure the message mapping by defining how the fields in the source system are mapped to the fields in the target system. You can use graphical mapping or XSLT mapping tools to create the mapping rules.
  • In the integration flow, configure the routing rules by defining when and how the messages are sent from the source system to the target system. You can use content-based routing or header-based routing to specify the conditions for routing.
  • In the integration flow, configure the error handling by defining how to handle any errors or exceptions that may occur during the integration process. You can use logging, alerting, retrying, or compensating mechanisms to handle errors.
  • Deploy and activate the integration flow.

How to Transfer Data from SAP C/4HANA to SAP BW/4HANA?

To transfer data from SAP C/4HANA to SAP BW/4HANA, you need to create DataSources in both systems that define the structure and properties of the data that can be extracted and loaded. You also need to create InfoObjects in SAP BW/4HANA that define the characteristics and key figures of the data that can be analyzed.

To transfer data from SAP C/4HANA to SAP BW/4HANA, you need to follow these steps:

  • In SAP C/4HANA, create DataSources for each type of data that you want to extract. You can use predefined DataSources or create custom DataSources based on your business requirements. You can also use CDS views or OData services as DataSources for some scenarios.
  • In SAP BW/4HANA, create InfoObjects for each type of data that you want to analyze. You can use predefined InfoObjects or create custom InfoObjects based on your business requirements. You can also use composite providers or open ODS views as InfoObjects for some scenarios.
  • In SAP BW/4HANA, create transformations that map the fields in the DataSources to the fields in the InfoObjects. You can use graphical mapping or ABAP mapping tools to create the transformation rules.
  • In SAP BW/4HANA, create DTPs (Data Transfer Processes) that define the extraction method, the load mode, the filter criteria, and the error handling for transferring data from the DataSources to the InfoObjects. You can use full, delta, or real-time DTPs depending on your data volume and frequency.
  • In SAP BW/4HANA, create process chains that schedule and execute the DTPs. You can use time-based or event-based triggers to start the process chains. You can also monitor and troubleshoot the process chains using the process chain monitor.

Conclusion

In this blog post, we have learned how to connect and transfer data from SAP C/4HANA to SAP BW/4HANA using DataSources. DataSources are objects that define the structure and properties of the data that can be extracted from a source system and loaded into SAP BW/4HANA. By creating DataSources in both systems, we can enable a seamless and secure integration between SAP C/4HANA and SAP BW/4HANA. We can also use CPI as a cloud-based integration platform that allows us to connect different applications and systems in a reliable way.
