Production Logistics and ERP Chapter 6
Production Logistics • Increased competitive pressures on production processes due to: • Shorter product development times • Focus on product quality • Shorter product life cycles • Production Logistics is SAP approach to production planning and control • Integrated with other Value chains in R/3 such as procurement and warehousing and SD.
Production Logistics (cont.) • Builds upon the integration of MRP II • Provides specific support for TQM and Kanban material management processes • More customer centric than MRP II with integration of sales information
R/3 Org. Elements Plant Storage Location Work center MRP area R/3 Business Objects Material master Production order BOM Sales & Operations plan Master recipe Production Logistics (cont)
Production Logistics Scenarios • Sales-order related production • Production by lot size • Sales-order related repetitive manufacturing • Project-oriented make-to-order production • Production replenishment

Autodesk Inc. Case • $400M Company, growing at 20%/year • Ten sales offices in US and 5 development centers in US and Switzerland with 1900 people • Sells famous CAD and MM software • Goal was to maintain growth rate and ship products within 1 hour of receiving customer order • existing system was stretched by global growth and couldn’t handle multiple order codes; operating info was not available to executives for decision making • Used R/3 to redesign business model and 25 major business processes, including 240 subprocesses • Re-engineered order process for automatic pricing; reduced number of order codes • Can track sales in real time along with new product evaluation copies and manufacturing costs around the world • Future plans were to extend the software to Europe and Asia regions, remote access, allow for product downloading
A Normal Company’s Systems • Fitter Snacker, Inc. • Founded in the ’50s • A small manufacturer of healthy snack bars • NRG-A and NRB-B bars • Two divisions; Wholesale and Direct Sales
Problems with Fitter Snacker’s Systems: • Sources: • Three unintegrated systems • Sales Order System • Warehouse System • Accounting System • Manual handling of transactions • Information not available in “real time”
Warehouse Sales Order Pick, Pack and Ship Quote Sales Fitter Snacker’s Sales Process Receiving Returns Invoice Accounting Payment Fitter Snacker’s Systems
Production and Materials Management at Fitter Snacker • Must answer the following questions: • How much of each bar should be produced? • What quantities of raw materials should be ordered? • When should raw materials be ordered
General Approaches to Production • Make-to-stock: Items produced in anticipation of orders • Make-to-order: Items produced to meet specific customer orders • Assemble to order: Final product assembled from make-to-stock items

Fitter Snacker Production Problems • Communications • Marketing does not share data with production (sales promotions and large, unexpected orders) • Inventory • True inventory status not known • No real-time data on actual sales • Accounting and Purchasing • Difficulty forecasting raw material and labor costs • Adjusting accounts for actual vs. standard costs time consuming and done infrequently
Production Planning Process • Work from sales forecast to create aggregate production plan • Break down aggregate plan into more specific plans • Use production plan to determine raw material requirements
Sales Forecasting Sales and Operations Planning Demand Management MRP Detailed Scheduling Production Purchasing SAP R/3 Approach to Production Planning
Demand Management • Calculation for Week 5 4,134 cases in Jan. x 3 days in week 5 ÷ 22 working days in Jan. = 563.7 cases 4,1984 cases in Feb. x 3 days in week 5 ÷ 20 working days in Feb. = 419.8 cases Total = 983.5 cases
MRP • Bill of Material
MRP • MRP Record
Detailed Production Scheduling • Snack bar production line is bottleneck • Scheduling of production line is key to determining detailed production schedule
Detailed Production Scheduling • Length of production runs • Longer runs reduces cost of setups • Longer runs increase capacity utilization • Shorter runs reduces cost of inventory
Providing Production Data to Accounting • Production data does not get entered into an ERP system directly • Many methods of gathering shop floor data are available • ERP allows shop floor data to be collected once for production and accounting purposes, and data is consistent in both areas

Supply Chain Management and ERP • ERP not required for Supply Chain Management (SCM) • ERP can facilitate sharing information in real time • Use of internet can reduce communication costs
Supply Chain Metrics • Total Supply Chain • Cash-to-cash cycle time: Time from paying for raw materials to the time when cash is collected from the customer • Total supply chain costs
Supply Chain Metrics • Buyer-Supplier • Initial fill rate • Initial-order lead-time • On-time performance
Summary • An ERP system can improve the efficiency of the production and purchasing processes. Efficiency begins with Marketing sharing sales forecasts with Production, which shares its production plans with Purchasing
Summary continued • Production planning can be done without an ERP system, but and ERP system allows production to be linked to Purchasing and Accounting. This data sharing increases a company’s overall efficiency
Summary continued • Companies are building on their ERP systems to practice supply chain management. In doing this, the company looks at itself as part of a large process that includes customers and suppliers. Using information more efficiently along the supply chain can significantly reduce costs.
