OAC OSFM and a Manufacturing Execution System: Compatible Partners Training Day January 17, 2007

NorCal OAUG Training Day Date: January 17, 2007 Slide: 2 Objectives  Outline the mechanics of PI’s interface project  Communicate the challenges encountered  Discuss the solution components employed  Share some tips and pitfalls

NorCal OAUG Training Day Date: January 17, 2007 Slide: 3 Agenda  Introduction - Power Integrations  Background on the Project  Overview of PI Supply Chain  Overview of OSFM Integration  Challenges and Considerations  Interface Components  Lessons Learned  Questions and Answers

NorCal OAUG Training Day Date: January 17, 2007 Slide: 4 Power Integrations Innovation in Power Conversion  Fabless Semiconductor Manufacturer  Headquartered in San Jose  Founded in 1988  Leading supplier of high-voltage analog integrated circuits (ICs) used in power conversion. –Enable compact, lightweight power supplies that are simpler to design and manufacture, more reliable, and more energy-efficient than those made with competing technologies. –Power a vast range of consumer and industrial electronics— computers, DVD players, TV set-top boxes, cell phone chargers, home appliances, telecom networking equipment, and many others.

NorCal OAUG Training Day Date: January 17, 2007 Slide: 5 Project Background – Business Considerations Issues:  Camstar MESA used for tracking production only  WIP/Inv Cost – done on massive spreadsheets  Extraordinarily long and painful month end close Solution:  Implement OSFM & Inventory to manage WIP valuation –In process Sort, Assembly, Test, Tape & Reel, etc –Wafer Bank, Die Bank, Untested, etc

NorCal OAUG Training Day Date: January 17, 2007 Slide: 6 Replace Spreadsheet Cost Accounting with OSFM Install interface engine, develop and test interfaces Project Background - Timetable Upgrade to from Order Management Inventory Purchasing Financials (GL/AP/AR/CM/FA) Human Resources Develop interface engine (eFabless) Receiving Inventory OSFM

NorCal OAUG Training Day Date: January 17, 2007 Slide: 7 Overview – Supply Chain

NorCal OAUG Training Day Date: January 17, 2007 Slide: 8 OSFM Integration

NorCal OAUG Training Day Date: January 17, 2007 Slide: 9 Challenges and Considerations  MESA uses single item number for multiple operations: –Wafer number for Wafer Bank, Sort, and Die Bank –FG number for Assembly, Test, and Finished Goods  Multiple Organizations with changes in inventory asset ownership  Not every transaction in MESA is necessary for Cost Accounting  Must avoid prematurely processing a “downstream” transaction for a given lot before “upstream” transaction is successfully played

NorCal OAUG Training Day Date: January 17, 2007 Slide: 10 Components – Getting Started - Tables The necessary tables for each transaction were identified

NorCal OAUG Training Day Date: January 17, 2007 Slide: 11 Components – Getting Started - Columns Every required column for each table was planned. eFabless rules were created for each (see Appendix for examples)

NorCal OAUG Training Day Date: January 17, 2007 Slide: 12 Components – Simplified Overview

NorCal OAUG Training Day Date: January 17, 2007 Slide: 13 Components – Example of Transactions

NorCal OAUG Training Day Date: January 17, 2007 Slide: 14 Components – Example of Transactions

NorCal OAUG Training Day Date: January 17, 2007 Slide: 15 Lessons Learned  API user guides are not always clear for example… –Initially used rcv_lots_interface for Receiving Deliver –Learned via TAR should be mtl_transaction_lots_interface  TRM Column descriptions are not always clear for example… –Column Name = PRODUCT_CODE –TRM description = Stores the product name to identify the source transaction for the record –Mandatory = No –Discovered it is required for Receiving Delivery (RCV)

NorCal OAUG Training Day Date: January 17, 2007 Slide: 16 Lessons Learned  Error messages are not always accurate for example… –RCV_TP_ACCT_PERIOD_CLOSED error caused by values unrelated to accounting periods. –Transactions set to ERROR status with no error message  Mapping the right rules and data values took longer than expected.  Need to be on the latest patchset  Recognize the need to properly staff for on-going monitoring of the transactions
