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

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”

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

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

• 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

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.
