SLT Replication

Last month I attended the HANA boot camp in Bangalore for three days. I went through many topics in this boot camp from what is HANA to SLT (SAP Landscape Transformation) replication. I realized that SLT (SAP Landscape Transformation) replication is the most important topic as existing SAP customers are already using legacy/old systems which would not be communicating directly to HANA system so customer wants to implement HANA as a part of business analytics then they have to understand the concept and overall working of SLT (SAP Landscape Transformation) replication.


LT (Landscape Transformation) replication server is the ideal solution for all HANA customers who need real-time (and non-real-time) data replication sourcing from SAP ERP systems into HANA. For LT replication server, we have to use add-on DMIS_2010_1_700 with SP04 and other system requirements are like NW 7.02. LT replication Server for SAP HANA will be part of SAP HANA software license model. LT replication Server for SAP HANA will be part of SAP HANA software shipment and fully integrated into the SAP HANA modeler UI.

 Transformation Capabilities:

The main purpose of SAP HANA is reporting of data of particular ERP content. Generally this will be done by a one-to-one replication of tables of the ERP into the new DB. Because of the customer specific requirement, it‘s necessary sometimes to filter, change or extend the original data within the load process into HANA.


• Change of data and/or table-structure within data replication/loading.

• Filtering which reduce to number of records to be replicated

• Definition of table structure to be used in HANA is maintaining in table IUUC_REPL_TABSTG


Release coverage: 4.6C onwards
Supports replication of non-Unicode to Unicode systems
Includes cluster / pool tables, etc. (writes into transparent tables in SAP HANA system)
Initial load functionality (proven in several huge client transfer projects) included in LT replication concept
Migration of data (structure and values) can be processed during replication (e.g. date fields to be migrated into strings)
Scheduling options for data replication available.
Still I have couple of doubts. I suppose most of the consultants who are new to HANA would be having the same.

How SLT server would communicate with the source system and HANA system?
How SLT would read the legacy system data and covert it to HANA format?
Which would be the right approach, whether to buy the whole new SLT server or to upgrade legacy system to new version?
