1 SAP TechEd Open Sesame: How Lockheed Paved the Way to Enterprise Procurement Analytics Pit C. Tan Session DMM LOCKHEED MARTIN CORPORATION. ALL RIGHTS RESERVED. 1

2 Who I Am Current role: Analytics and Reporting Tech Lead and Lead Engineer for LM s Corporate Procure-To-Pay (P2P) application Technology includes BW HANA, HANA side-car, BOBJ ABAP Acceleration (side-car), HANA modeling, SLT data replication (sources: SUS, SRM, and ECC) Migration of Oracle databases to HANA Exposing Procurement data from BW and transaction systems Investigating SAPUI5 with HANA backend (via ADBC) Investigating SoH for ECC. HANA upgrades & system management with Basis Experience with: SAP MM, QM, and Material Cost Estimating 2

3 Who Are We Lockheed Martin Corporation (LM) Global defense, security, aerospace, and advanced technology company. The majority of Lockheed Martin's business is with the U.S. Department of Defense and U.S. federal government agencies. Lockheed Martin operates in five business areas (BA s) Aeronautics, Information Systems & Global Solutions, Missiles and Fire Control, Mission Systems, and Training and Space Systems. 112,000 employees worldwide 2014 Sales of 45.6 Billion USD The Corporation's New York Stock Exchange symbol is LMT and its web-address is 3

4 Lockheed Martin and SAP 1996: First licensed SAP 1999: One of the first certified SAP Competency Centers 2013: BW HANA (P2P), BI HANA side-car (P2P) The Lockheed Martin SAP Landscape 10 SAP Finance and Operations systems, including international Enterprise Procurement/Accounts Payable/MRP Single Solution Manager system Various BW, Business Objects and HANA implementations 4

5 Learning Points Satisfy diverse LM BA requirements Use Cases satisfying requirements Using HANA to expose SAP BW and ERP/SRM/SUS data Monitoring system Issues Lessons Learned Future 5

6 Satisfy diverse LM BA requirements Enable businesses to make real-time information driven decisions Reduce cost and reporting cycle time thru a simplified and agile open access model Open Architecture supports BA system access Join P2P with BA top level data analytics Self-service analytics for power user 6

8 Use Cases satisfying requirements BA HANA via Smart Data Access (SDA) BA BOBJ via JDBC or ODBC P2P BOBJ self-service shareable queries Provide alternative to SQVI/SE16(N) for increase productivity Oracle via ODBC Microsoft SQL Server & Reporting tools via ODBC BW InfoProviders are available via HANA Information Views and SQL Views ( Extracts ) 8

10 Using HANA to expose BW, ERP, SRM, SUS BW HANA Expose BW modelled data thru HANA Information Views and SQL Views BI HANA Expose SUS, SRM, and ECC tables SLT for SUS, SRM, and ECC schemas HANA Database ID Security 10

11 BW HANA How to Import BW Objects to HANA Information Views? Required HANA security settings HANA Studio steps URL Information SQL Views? Can be utilized to use Information Views so that the metadata can be customized to suit BA needs like using a custom schema name instead of _SYS_BIC or custom field names instead of the BW names. Can resolve shortening of names to 30 character limit for schema, table, and column name in a SELECT statement. 11

12 BI HANA Replication Setup - Create three SLT Server Configuration ECC ECCDB schema SRM SRMDB schema SUS SUSDB schema 12

13 HANA Database ID Security Provide a read-only database id using HANA user type Restricted Advantage Read only compared to a typical database id When created it has no privileges unlike the typical database id where it gets PUBLIC Add privileges only to SCHEMA or tables or objects it has read access to Cannot see system information in SYS schema URL Information 13

15 Monitoring system - Auditing Setup HANA Auditing: Show top tables used and by which user Tables not used for a period of time that consume large memory can be removed Show SQL statements used URL Information Tips on what to audit: Define who you want to track and why Do not track SLT ids will add lots of entries Consider not tracking ABAP Accelerator id 15

16 Monitoring system - Memory Monitor Loads and Unloads Turn on Most Expensive SQL Trace Consider turning on maximum memory used for queries. SPS08 is global only. SPS09 or SPS10 supports per database id 16

18 Issues Oracle instances that are configured ASCII have data truncated. P2P BW and BI HANA are both Unicode. Resolved by creating SQL Views with function TO_VARCHAR. Oracle Gateway configuration settings were difficult to figure out at first. There are specific settings that were not clear. Eventually found correct gateway configuration for both Oracle setup as ASCII and non-ascii. me if needed. Oracle Gateway does not always send the exact query. In one query, it removed the WHERE clause thereby retrieving all records from HANA. Redesigned Oracle query although not always the most efficient but better than no WHERE clause coming into HANA. 18

20 Lessons Learned Good communication plan that includes Business Analyst Leads versus the Power Users or BAs. Understanding of data and SQL Savvy (have used SE16(N) and SQVI). HANA provides standard SQL objects not just Information Views. Productivity opportunity versus using SQLVI/SE16(N) Performance can be an issue when JOINING tables that are located in separate servers. 20

22 Future Possibilities: Delivered content to HANA side-car: RDS, HANA Live, BW Content (DXC) Convert standard and custom BW modeled data to BI HANA (side-car) Lumira self-service Power User ability to share Universes and WebI Free Hand SQL in the repository Upgrade to ECC, SRM, and SUS might create issues with SLT. This could pose a down time. Latest SLT version do support systematic structure changes from sources 22
