Designing, implementing, and running your SAP applications at peak performance 24 hours a day has never been more vital for your business success than now.

This guide provides a starting point for managing your SAP applications and maintaining and running them optimally. It contains specific information for various tasks and lists the tools that you can use to implement them.

This guide also provides references to the documentation required for these tasks, so you will sometimes also need other Guides such as the Master Guide, Technical Infrastructure Guide, and SAP Library.

Target Groups  Technical Consultants  System Administrators  Solution Consultants  Business Process Owner  Support Specialist

SAP Application A SAP application is an SAP software solution that serves a specific business area like ERP, CRM, PLM, SRM, and SCM.

Business Scenario From a microeconomic perspective, a business scenario is a cycle, which consists of several different interconnected logical processes in time. Typically, a business scenario includes several company departments and involves with other business partners. From a technical point of view, a business scenario needs at least one SAP application (SAP ERP, SAP SCM, or others) for each cycle and possibly other third-party systems. A business scenario is a unit which can be implemented separately and reflects the customer’s prospective course of business.

The SAP Landscape Transformation (SAP LT) Replication Server is the SAP technology that allows you to load and replicate data in real-time from ABAP source systems and non- ABAP source systems to an SAP HANA environment.

The SAP LT Replication Server uses a trigger-based replication approach to pass data from the source system to the target system.

The SAP LT Replication Server can be installed either as a separate SAP system, or if the technical prerequisites permit, on an ABAP source system.

In order to replicate data, you must first define the parameters that the SAP LT Replication Server will use to replicate data from one or more source systems to one or more target systems. You specify this information in a Configuration. A configuration contains information about the source system, the target system, and the relevant connections. You define configurations in the SAP LT Replication Server.

You use a configuration to load and replicate data from one source system to one target database schema of a HANA system (1:1), or from multiple source systems to one target database schema of an SAP HANA system (N:1). Furthermore, it is possible to load and replicate data from one source system to multiple (up to 4) target database schemas of one or more HANA systems (1:N). You can also specify the type of data load and replication

- either in real-time, or scheduled by time or by interval.

The trigger-based data replication approach is a table-based concept that retrieves data from application tables in the source system (or source systems). A user uses the SAP HANA Studio to select the tables for the replication.

If not all data records of a table should be transferred, you can create transformation rules to selectively filter the data (selective data replication) or to enable other transformations during the data replication process.

The following graphic outlines the basic concept and the typical landscape (for an ABAP source system) using the

trigger-based data replication approach of the SAP LT Replication Server:

–  –  –

The SAP LT Replication Server can be used for data replication from ABAP source systems and non- ABAP source systems to the SAP HANA system. In the Configuration & Monitoring Dashboard (transaction LTR) of the SAP LT Replication Server, you can define a new configuration that contains the relevant information required to create the connection between the source systems and the target SAP HANA systems.

The technical landscape consists of following components:

 ABAP source system (or systems) The source system tracks database changes by using database triggers. It records information about changes in the logging tables. Read modules (located on the ABAP source system) transfer the data from the source system to the SAP LT Replication Server. The relevant data is read from the application tables.

 Non-ABAP source system (or systems) The non- ABAP source system tracks database changes by using database triggers. It records information about changes in the logging tables. Read modules (located at the SAP LT Replication Server) transfer the data from the non-ABAP source system to the SAP LT Replication Server. The relevant data is read from the application tables.

SAP LT Replication Server An SAP system that facilitates the replication of data from one or more source systems to one or more target systems. The source systems can be SAP or non- ABAP systems.

 SAP HANA system The SAP HANA system contains the SAP HANA database. It is used to store the replicated data. The SAP LT Replication Server and the SAP HANA system communicate by means of a database connection.

Prior to the installation, it is important to understand the various system landscape options available:
