The material management process-a number of business process difficulties in managing materials include

A
  • inventory management–defining the best inventory policy and managing the inventory balance so there is adequate but not too much inventory.
  • material selection–different material numbers that describe the same material. a material may be identified by more than one material numbers which means you are not getting the best price.
  • material sourcing–too many sources for the same material. leads to not getting best price.
  • inactive materials–having obsolete materials that are not currently in your products take up space on your database. purging inventory of inactive materials. identifying the replacement material.
  • maintaining data in SAP–centralized vs decentralized data maintenance responsibility. inadequate IT security for data maintenance.

defining acceptable BOM/routing combinations and under what circumstances which should be used.

183
Q

Production Versions are a hard requirement for several SCM solution areas:

A

189
Q

There are several different types of independent demand that may or may not be relevant to Material Requirements Planning:

A
  • customer demand (sales orders)
  • planned independent requirements (forecast)
  • stock transport request
190
Q

In effect, demand management acts as

A

a funnel to translate requirements or forecasts from a number of different sources to which Material Requirements Planning (MRP) and Master Production Scheduling (MPS) can plan.

191
Q

The result or output of Demand Mangement is

A

a Net Requirement to MRP

192
Q

Demand management is

A

directed and governed by fields in the Material Master, primarily the Requirement Strategy field.

193
Q

The output from demand management will feed

A

MRP

194
Q

Demand management in SAP primarily works with what type of demand?

A

independent demand.

195
Q

A

planning of requirement quantities and requirement dates for finished products and important assemblies, and definition of the strategy for producing or procuring a particular finished product.

196
Q

The output(s) from demand management are:

A

planned independent requirements (PIR)
net quantities
required dates

197
Q

Production types

A

make to stock
make to order
assemble to order

198
Q

Make to stock

A

in a make-to-stock strategy, inventories must be on-hand before the demand arrives.
the retail industry and many other industries use this strategy.

199
Q

Make to Order

A

in a make-to-order strategy, inventories are not planned until an order arrives.
The aerospace and defense industry uses this strategy.

200
Q

Assemble to order

A

in an assemble-to-order strategy, semi-finished and raw material inventories must be on hand prior to the arrival of actual demand.
However, finished product inventories are not planned until demand arrives.
The computer industry uses this strategy.

201
Q

The planning strategy represents

A

the procedure for what triggers quantity and timing of production of a material.

202
Q

A material production may be triggered by:

A

a forecast only
a combination of a forecast and a customer order
a customer order only

203
Q

A

businesses’ demand fulfillment method (i.e., make to stock, make to order, assemble to order)

204
Q

The potential inputs into the demand management function in SAP include

A

material forecasts
sales plan
production plan

205
Q

Forecast consumption also known as forecast netting is

A

the process of automatically adjusting the forecast to reflect actual customer orders that have been received.

206
Q

The objective of the forecast consumption is

A

to reduce the possibility of over-producing.

207
Q

Planning strategies

A
  • planning uses planned independent requirements.

- deliveries for sales orders are taken from the warehouse stock.

208
Q

Make-to-stock Planning

A
  • Planning with final assembly–>STR 40

- Make-to-stock Production–>STR 10

209
Q

Strategy 10- Make to stock

A
  • strategy 10 is appropriate when the following conditions exist:
  • -product cycle time > time customer willingness to wait.
  • -production volume is high and repetitive.
210
Q

With strategy 10 Demand management will NOT consume.

A

it ignores any customer orders and allows the full forecast to be passed to MRP as net demand.

211
Q

Strategy 40- Planning with final assembly

A

Strategy 40 CONSUMES forecast.

  1. planning at finished product level using plnd ind. reqmts.
  2. sales orders consume planned independent requirements.

the calculated warehouse stock that is available to promise to any future customer (sales order).
ATP is a highly configurable function within SAP.

218

-it will display in ascending time sequence all the demands (requirements) and supplies (stocks) for a material.

219
Q

Replenishment planning is a

A

major activity in any supply chain management business function.
A variety of replenishment planning techniques are available in SAP R/3 and APO.

220
Q

All replenishment planning techniques basically attempt to answer the following questions:

A
  • what materials to buy or make (what materials should be purchased or produced)
  • how many to buy or make (how many should produce or buy)
  • when material should arrive (when will new supplies be needed)
  • when should we start making or buy the material (who should we buy from or where should we produce the material)

-DOES NOT ATTEMPT TO ANSWER–>how to store material made or purchases.

221

223
Q

independent demand

A
  • generated by customer orders for finished product.

224
Q

Examples of independent demand in SAP include

A

forecasts

225
Q

Dependent demand

A
  • generated from higher level items
  • lumpy..not dispensed uniformly.
  • requires inventory just prior to need.

month 1:push mowers

month2: mulching mowers
month3: tractors
- –>special parts used for just one item.

226
Q

Dependent demand is calculated from

A

higher demand.

227
Q

Historical Handling of Dependent Demand

A
  • Difficulty of ordering & scheduling assembled products…
  • -Enormous task of…
  • Setting up schedules
  • Keeping track of large numbers of parts & components
  • Coping with schedule & order changes
  • –Using inventory techniques for independent demand
  • –>excessive inventories!!
228
Q

Material Requirements Planning (MRP)

A

computer-based information system that translates master schedule requirements for end items into time-phased requirements for subassemblies, components, & raw materials

229
Q

MRP supplies the answers to

A

what is needed
how much is needed
when is it needed

230
Q

Material Requirements Planning (MRP)

A

Producing or purchasing the RIGHT materials
at the RIGHT time
& having them available at the RIGHT places

231
Q

Material Requirements Planning (MRP)

A
  • Creates schedules identifying…

234
Q

MPR Inputs: Master Production Schedule

A

time-phased plan specifying

timing & quantity of production for each end item

235
Q

Master production schedule (MPS)

A

The master schedule states which end items are to be produced, when they are needed, & in what quantities.

The quantities in a master schedule come from a variety of sources, including customer orders, forecasts, & orders from warehouses to build up seasonal inventories.

The master schedule separates the planning horizon into a series of time periods or time “buckets,” which are often expressed in weeks.

However, time buckets need not be of equal length.
In fact, the near-term portion of a master schedule may be in weeks, but later portions may be in months or quarters.

Usually, plans for those more distant time periods are more tentative than near-term requirements.

236
Q

MRP Inputs: Master Schedule

A

sum of lead times that sequential phases of a process require, from ordering of parts or raw materials to completion of final assembly

237
Q
