SAP HANA Data Provisioning Options: 1. SAP LT Replication Server SAP LT Replication Server does not have to be a separate SAP system and can run on any SAP system with SAP NetWeaver ABAP stack 7.02 or higher with SAP Kernel 7.20 (or higher) SAP source system SAP LT Replication Server SAP HANA system HANA Studio Application Table Replication Configuration Application Table Trigger Based Delta Recording RFC Connection Replication Engine DB Connection Connection(s) between source system and SAP HANA system are defined as “Configuration” on the SAP LT Replication Server Data load and replication are triggered via SAP HANA Studio

SAP LT Replication Server LT Replication Concept: Trigger-Based Approach Architecture and key building blocks SAP source system SAP LT Replication Server SAP HANA system Read module RFC Connection Structure mapping & Transformation Application table Logging table Application table Write module DB Connection DB trigger Efficient initialization of data replication based on DB trigger and delta logging concept (as with near zero-downtime approach) Flexible and reliable replication process, incl. data migration (as used for TDMS and SAP LT) Fast data replication via DB connection LT replication functionality is fully integrated with HANA Modeler UI

SAP LT Replication Server LT Replication Concept: Trigger-Based Approach Replication from non-SAP sources Non SAP source system SAP LT Replication Server SAP HANA system DB Connection Read module Application table Logging table Structure mapping & Transformation Application table DB Connection Write module DB trigger SAP LT replication server transfers in a first step all metadata table definitions from the non-SAP source system to the SAP HANA system into the tables DD02L and DD02T. Read module now has to reside on LT replication server as it requires an ABAP stack. NOTE: For non-SAP source systems, the customer database license needs to cover a permanent database connection with 3rd party products like LT replication server.

SAP HANA Data Provisioning Options: 2. SAP Data Services 4.1 High Performance Highly-scalable engine to move large volumes of data into HANA Integrated with HANA’s bulk-load interfaces Wide Connectivity Data and Metadata connectivity to all major enterprise data sources Native, fast connectivity to Applications, RDBMS, Files, Text Powerful Transformations Built-in transformations for data quality (*) Support for non-relational data formats including text and XML SAP HANA Appliance SAP HANA DB In-Memory SAP Business Suite SAP HANA Studio SAP BW *1 SAP Data Services 4.1 Structured/Text Data Sources (*) = Requires additional licenses

NEW in SAP Data Services 4. 1 NEW in SAP Data Services 4.1* Data Services Workbench for data loading into SAP HANA New, Eclipse-based user interface design for Data Services A simple wizard to replicate data and metadata (table definitions) from 3rd party databases into SAP HANA. In 3 easy simple steps, you can replicate large data sets from any source to your SAP HANA target: Set up connections to source and target system Select the required tables from the source (or simply select all tables) Generate and execute the job to move all data with one mouse click Once the wizard exits, more additional features can be added: Filters, complex data mappings (expressions and functions) Load options, delta loading strategy, etc. *SAP Data Services 4.1 - RTC in June 2012

SAP Data Services 4.1 – Workbench Design Replication job HANA (8 selected tables) Step 3: Deploy your Data Services job and execute. Step 1: Select source and target connections (database or SAP application). Step 2: Select tables for replication, target tables will be generated automatically.

SAP Data Services 4.1 – Workbench Monitor job run Built-in capabilities to monitor the data loading Compare historic load times See load progress in real-time

Activation Processing SAP HANA Data Provisioning Options: 3. SAP HANA Direct Extractor Connection (DXC) Leverage pre-existing foundational data models of SAP Business Suite entities for use in SAP HANA data mart scenarios Significantly reduces complexity of data modeling tasks in SAP HANA Speeds up timelines for SAP HANA implementation projects Provides Semantically Rich Data from SAP Business Suite to SAP HANA Ensures data appropriately represents the state of business documents from ERP Application logic to “make sense of the data” already built into many extractors Simplicity / Low TCO Re-uses existing proprietary Extraction, Transformation, and Load mechanism built into SAP Business Suite systems, over a simple http(s) connection to SAP HANA No additional server or application needed in system landscape Change Data Capture (delta handling) Efficient data acquisition – only bring new or changed data into SAP HANA DXC provides a mechanism to properly handle data from all delta processing types SAP ERP Extractor DataSource (flat structure) Embedded BW DataSource PSA generic data transfer InfoCubes Data Store Objects InfoObjects SAP HANA Activation Queue Active version In memory DSO Status Activation Processing ERP data http

SAP HANA Direct Extractor Connection: Details - 1 - SAP HANA Direct Extractor Connection (DXC) Utilizes the Data Source extractors that exist in SAP Business Suite systems  Originally, those were developed for use with BW DXC is for use in SAP HANA standalone scenarios (data mart); BW on SAP HANA is a separate topic. DXC utilizes the embedded BW Starting with NetWeaver 7.0, (embedded) BW has been part of NetWeaver ABAP In typical SAP Business Suite systems, the embedded BW is not utilized customers used to run separate BW systems Most customers already have the Support Package level needed on source SAP Business Suite system, e.g. SAP NW 7.0 Support Package Stack 19 – first available Nov 2008 DXC uses the embedded BW system to enable extraction towards SAP HANA and monitoring DXC mainly requires applying SAP note 1583403 Note: Modeling in the embedded BW is not part of the DXC solution. An architectural variation is available, which uses a “sidecar” BW instead of the embedded one.

SAP HANA Direct Extractor Connection: Details - 2 - The extraction from the SAP Business Suite system is controlled by the Data Warehousing workbench inside the embedded BW When data is extracted from, the SAP Business Suite system, it is not loaded into the PSA of the embedded BW - it is redirected instead and sent to SAP HANA it gets loaded into in-memory DSO’s activation queue - and then gets activated into the active table of the in-memory However, in the data load monitor of the embedded BW, the data load into the activation queue in the DSO in SAP HANA appears like data is loading into the PSA of the embedded BW Delta processing (aka “change data capture”) Works the same for DXC as it would if BW is the receiving system If the DataSource is delta enabled, then delta-data is available with SAP HANA Direct Extractor Connection, too DXC internally in HANA uses The ICM (Internet Connectivity Manager) receives XML packages over the http(s) connection A mechanism written on the XS Engine (special runtime component for SAP HANA) receives data packages from ICM, converts format inserts the records into the activation queue of the in-memory DSO activation processing -> records go into the active table in proper sequence Both the ICM and XS Engine components must be enabled in SAP HANA to utilize DXC
