SAP Landscape Transformation Replication Server (SLT) is a standard software to move and synchronize data in real time, between different systems within the same network, wide area networks, or into the cloud. It can be used in different scenarios to solve diverse customer problems in various functional areas. It is positioned for real-time (trigger-based) data replication from ABAP and non-ABAP sources, and only on SAP NetWeaver supported databases. (See SAP Help Portal.) This ensures that information is in the right place at the right time.
The software helps with the following:
Feeds analytical systems with up-to-date business information from the productive system landscape
Supports the acceleration of large volume transactions executed in SAP HANA
Enables real-time reporting
Minimizes transfer volume for SAP Business Warehouse (SAP BW)
Enables synchronization between different systems
Key Concepts of SLT
- Replication
Real-time or scheduled
Delta capturing to minimize transfer volume
- Transformation
Filtering, using selective criteria
Adjustment of tables
Conversion of data
- Installation and Operation
Deeply integrated within SAP landscapes so that it can reuse existing installation and monitoring capabilities
Monitoring with SAP Solution Manager 7.1 SP5 onwards
The delta capturing technology of SLT (also named change data capture (CDC) recording mechanism) is based on database triggers on tables in the source systems. It will be explained more in detail in Unit 2 Lesson 1 Understanding the Architectural Concept.
This delta can be transferred in either real time or scheduled data transfers. Data can be modified as follows:
Enriched
For example, you can add further information, such as the SID of the source system.
Adjusted
For example, you can make adjustments if you want to transfer HR-related data that needs to remain anonymous.
Filtered
You can skip irrelevant data.
Converted using transformations
For example, you can perform data type conversions because different systems are used as a source and as a target.
Because SLT is based on SAP NetWeaver, SAP S/4HANA Foundation, or embedded in SAP S/4HANA, you can integrate it into the existing SAP landscape easily. For example, you can monitor the data replication within SAP Solution Manager (from 7.1 SP5 onwards). Please refer to the Installation Guide at http://help.sap.com/sapslt.
