1 SAP HANA Extended Application Services Native Development: Lockheed Martin DEV112 Tim Champagne Lockheed Martin Derek Since Deloitte Consulting

2 Learning Points Learn a real world example of the decision criteria put in to using SAP HANA XS Learn a little bit about what SAP HANA XS really is Understand the key considerations and resources available when getting started with SAP HANA XS 2

3 Best Practices If you do not have a SAP HANA XS skilled developer, one that is experienced in object oriented application development can get up to speed quickly Take the time to read over the developer guide before starting development Understand your application functional and security requirements and how to implement them with SAP HANA XS 3

4 Key Learnings When and when not to use SAP HANA XS Best resources to use while developing Tips and Tricks for development How to implement user security with SAP HANA XS 4

5 LM Tech Overview & Project Background Project Overview The Lockheed Martin Advanced Analytics project was designed to improve the overall supply chain performance and thereby help client save on cost and time. The Lockheed/Deloitte team consists of supply chain experts, SAP and HANA technologists and advanced analytics modelers. Database SAP HANA HANA DB size Average Monthly Volume of data replicated Frequency of data replication 1/2 TB(in memory), 7 TB 200 GB Daily Technical Environment ~Source systems spanning across multiple platforms ( SAP ECC, SQL Server, Excel, PIOS etc.) through SLT or BO Data Services via flat files HANA rev 82, BOBJ 4.1 # of HANA tables Max Size of HANA tables Results 1 billion rows (CDR records) # of Information Views Around 200 (for initial release) comprised of HANA Views (Attribute, Analytic, Calculation) Data granularity in HANA Query data volume With SAP HANA, Lockheed has been able to efficiently analyze many billions of rows of data in as little as 16 seconds. Executives can now dynamically aggregate, analyze supply chain performance to deliver more effective results. Atomic 100M< rows The business is now using the results to attack the most impactful part long lead times as well achieving a level of demand planning not possible before 5

6 Span Compression Tool Overview 6

7 Ticketing System Overview Lead Time Accuracy and Compression tickets will capture key data about lead time correction activities and will allow for dialogue/direction between the Overall Demand/Supply organization and the various executing functions. 7

8 Why use SAP HANA XS? Some of the basic requirements around building a ticketing system were: 1) The need to write back to a HANA DB 2) A user friendly front end that hundreds of buyers will be using on a daily basis Option 1 Use JIRA or HP QC and build an interface back to HANA Pro - Quick front end development and existing resources with product knowledge Con - Potentially complex interface build Option 2 Custom App using a coding language such as JAVA or C++ with connection to SAP HANA DB Pro - Could draw on a larger resource pool Con - Environment integration could be complex or potentially not as natural as XS Option 3 HANA XS Pro - In the sweet spot of what XS is built for, simplified system architecture, provides solid base for future custom apps Con - New/Unknown technology 8

9 What is SAP HANA XS? Client UI s handle the presentation logic Applications handle the control flow logic SAP HANA handles the calculation logic 9

12 Key Development Knowledge Points Data Services OData Service Open specification standards for communicating data over the web. Any existing HANA table or view is able to be used by the OData service. Supports CRUD operations, query parameters. 12

13 Key Development Knowledge Points User Handling Application-access Controlled by creating a.xsaccess file Authenticate User through Single Sign On Check for specific roles assigned to the user. SAP HANA User Creation Standard vs. Restricted SQL Configuration Connection (SQLCC) Logon maps to the personal DB user User only needs XS Privileges XS Privilege checks are done with this user Packages with configured default connection All SQL connections (xsjs and OData) are opened for the configured connection, which is thus used for checking all SQL privileges 13
