Hi friends of SAP Datasphere and data warehousing
you probably know hat SAP Datasphere incorporates the ideas of a Data Warehouse - loading data from multiple sources to a staging layer and further to higher layers of integration.
In SAP Datasphere, Replication Flows and Transformation Flows serve different but complementary purposes. Combining them allows organizations to efficiently move data from source systems into Datasphere while also preparing that data for analytics, reporting, and other business use cases.
A Replication Flow is primarily responsible for moving data from a source system into SAP Datasphere. It can replicate data from supported sources and, depending on the source and configuration, can support both initial data loads and subsequent changes. The main objective is to bring data into Datasphere efficiently while minimizing the need to repeatedly extract the same information from the source system.
A Transformation Flow, in contrast, is focused on processing and transforming data. Once data is available in Datasphere, a Transformation Flow can perform operations such as filtering, joining, mapping, aggregating, cleansing, and enriching data. It essentially converts raw or operational data into a structure that is more useful for analytical purposes.
The two flows can therefore be viewed as stages of a data pipeline:
source --(Replication flow )--> data acquisition layer (primary storage) --(Transformation flow )--> data harmonization layer (secondary storage) [ optional: --(Transformation flow )--> business transformation layer ] [ optional: --(Replication flow )--> open hub / outbound data hub ]
This approach is similar to a traditional layered scalable architecture in SAP BW or SAP BW/4HANA:
The first step is fast and delta-capable integration of raw data from a source with minimal changes. This reduces the stress on the source system
The second step is the full power of transformation and data integration.
Additionally, you can create a business data layer (data mart) by a higher level transformations if they are complex enough to justify data storage. In most cases, views will be sufficient to provide calculations for business requirements.
In cases in which exposing views is not viable, additional data replicatoin may be necessary to leverage the transformed data sets outside of the data warehouse (open hub concept) or to retract data back to the source system.
Summary
The key principle is that Replication Flows answer “How do I efficiently get the data into Datasphere?” while Transformation Flows answer “How do I turn that data into useful information?”
By integrating the two types of flow, you can build scalable and reusable data pipelines in SAP Datasphere.

For instructer-led training, search for the training "Introduction to SAP Datasphere" (DSP01) in which you will perform exercises for these tasks.
take part in the great journey of data from your sources to SAP Datasphere: Join the live session
SAP Datasphere - Replication Flow - Loading delta data from SAP S/4HANA.
We will demonstrate how to define a replication flow, and how to be efficient: instead of loading the same records again and again, you need only to load changed and new records. For this purpose the "Replication flow" of SAP datasphere can be implemented and scheduled in delta mode. Of course, it depends on the source object if and how this option is available.
