Identifying SAP BW/4HANA Source Systems and Their Use Cases

Objective

After completing this lesson, you will be able to identify SAP BW/4HANA Source Systems and Their Use Cases

Source Systems for Data Provisioning in SAP BW/4HANA

Overview of Source Systems

Source Systems in SAP BW/4HANA.

With SAP BW/4HANA, you find the following source systems:

Moreover, there are other options without a DataSource:

  • You can use a CompositeProvider as a source of a transformation and a Data Transfer Process. If you include your source data through a virtual table or synonym into an SAP HANA calculation view, you load from many sources through a SAP HANA calculation view and CompositeProvider. The Data Transfer Process of this scenario works only as full Data Transfer Process.
  • For simple cases, you can access any source using the DataStore Object (advanced) property direct update to delete data or push data into the active data of a DataStore Object (advanced).
  • If you need quality management, a change log with rollback option and delta extraction to further targets, you can access any source using the DataStore Object (advanced) setting write interface enabled to push data into the inbound queue of a DataStore Object (advanced).
  • Even without the setting write interface enabled, you can directly upload data from a flat file into the inbound table of a DataStore Object (advanced) using the SAP BW/4HANA Cockpit. A new request will be generated.

Note

These options without DataSource are not intended for mass data update. The standard recommendation for mass data load is a scheduled process chain or a streaming process chain (a streaming process chain does not work for all sources). Alternatively, SAP has developed another new transfer scenario through the REST(HTTP) API or through the RFC function RSO_PUSH_SEND_STRING with the optional parameter MESSAGING=X (Refer to SAP Note 3283799 https://launchpad.support.sap.com/#/notes/3283799).

Maintaining Source Systems

Perform maintenance of source systems with BW Modeling Tools or SAP GUI

You can perform maintenance of source systems with BW Modeling Tools or SAP GUI.

Monitoring Source Systems

Check Source Systems screen.

You can review and check the source systems using transaction RSA1. Choose Administration and expand the source systems folder Source Systems. Choose the Manage Source Systems link. In the Check Source Systems screen, you can see all of your systems, what type they are, and also if they are replicated or not. Choose Execute to see if the connection is OK.
