This is my first Blog post. I have 8 years of experience in SAP Netweaver Basis, HANA and Solman. I have a tremendous experience on both Implementation and Support projects. Recently I implemented the SLT solution for one of the customers and thought to share the knowledge with everyone. I am also thinking to publish blogs on SLT Configuration from SAP to non-hana target(rare scenario) and system replication setup & DR Invocation for HANA. Please stick around!!!
SAP Landscape Transformation Replication Server (“SLT”) is used for real-time or scheduled data replication from SAP or non-SAP source. This uses trigger-based technology to transfer the data from any source to SAP HANA in real-time. You can even transfer the data to non-hana target provided the source is SAP system.
The SAP LT Replication Server is technically based on SAP Netweaver 7.00 EHP02 (minimum support package 😎 or higher. Always prefer to install the latest Netweaver Version.
I chose NW 7.5 SP9 and MS SQL 2012 for installation on OS Windows 2016.
