Why Are We Here?

If you manufacture complex products, or multi-variantproducts

If you need to offer your customers high levels of

customization (configuration) If you cant possibly keep all poss ible variants in stock,

but you need flexibil ity and fast reaction to marketdemand

If Sales, Engineering, Planning, and Production areoverwhelmed with an enormous amount of data tocreate and maintain

Why Are We Here? (cont.)

Then you need to streamline the information flowacross your organization using SAP VariantConfiguration (VC)

This session will walk you through the steps of buildinga simple VC model

Who Should Use Variant Configuration?

Example of industri es relevant to SAP VC:

Aircraft

Bicycle

Motorcycles

ElevatorSystems

PCs

Pumps

Furniture

Product

Complexity

Mass

Production

Automobiles

Why Variant Configuration (VC)?

Why should VC be used:

Example: You operate a SUBWAY franchise, you run SAP,your prici ng and lead time must be based on the exactorder (options)

The options youll be asked for the Italian B.M.T. are:

- 6

- 12

BreadLength - pepper

- onion

- olive

- lettuce

- cucumber

Toppings

- vinaigrette

- ranch

- caesar

Dressing

-Yes

- No

Grilled?- Regular

- Italian

- Herbs

- Oat and

Honey

Bread

(choose exactly one) (choose exactly one) (choose one

or none)

(choose exactly one)(choose any

combination)

& & & &

4 2 32 4 2x x x x(any + none) (3 + 1)

= 2,048 variants!!

7

Why Variant Configuration (VC)? (cont.)

In this example (and if there are no other restrictions),your organization wou ld need to create and maintain2,048 data sets (Material Masters, BOMs, Task Lis ts,Costing, and Pricing records)!

Plus:

Maintenance: One more dressing option would add 512 newdata sets

Sales Order entry: Which material number to enter?

New rules or restrictions (Example: If Italian bread chosen,

dressingmust be

vinaigr ette, etc.)

Multi-level Bills Of Materials:

For more complex products, configuration can be done atany BOM level

Characteristic values can be passed from any level to anylevel

Purchase Orders for lower level materials can therefore beconfigured

Dimensions (geometrical measures) can beconfigured and inferred

Example: Window si ze: width= (2 x w1) + w2

3 variables, one equation

Any 2 var iab les must be assigned values (not al l of 3)

Last value is in ferred*

width

w1 w2

* need to use Constraints


Price configuration:

Pricing in SD (based on conditions) will read the characteristicvalues of a configurable material

Price is therefore dynamically calculated duri ng configu rationin the Sales Order entry sc reen

Classification: Characteristics

Characteristics are standard SAP Classification objects

They represent the possible options you will need toset when configuring a product

VC is about assigning values to characteristics (valueassignment)

Values can also be deducted and/or inherited

21

Classification: Characteristics (cont.)

Example of characteristics and value assignments:

[Type of engine]

Possible values: 4 cylinder, V6, V8

[Length of shaft]

Any value wi th in the range 3040 CM

[Gloss finish?]

Yes or No

[Toppings]

Pepper, Olive, Onion, etc.

Reference Characteristics:

assignment may be dependent on those)

Change field content with dependencies:

Change BOM quantity or Operation Duration (based on

value assignment)

One characteristic can be assigned to many classes

Classes of class type 300 coll ect and manage thecharacteristics to which you assign values in the Sales Order

Class item (category K) (aka Class node)

You assign a class (type 200) as a BOM item

Example: Class: COLOR

Characteristic: COLOR

Possible values: Blue, Red, Green

You assign this class to materials (possible components) andclassify them:

Material Raw1 Blue

Material Raw2 Red

Material Raw3 Green

During value assignment (configuration), you assign a valueto this item (example: Red), and the BOM component isdetermined accordingl y

39


Class nodes are a simple way to handle some basicproduct configuration (without using ObjectDependencies)

40

41

Master Data: Task List (Routing)

Super Routing :

Same principle as Super BOM

Regular routing that contains all possible sequences,

operationsand PRTsfor all possibl e variants Dependencies will act as filters

Note that dependencies can be assigned to sequences(alternative and parall el), operations, and PRTs

BOM items (for example, to change the quantity)

Routing operations (for example, to change standard values)

Examples:

BOM quantity of BREAD is 0.5 if BREAD_SIZE = 6

Operation Preparation is 5 seconds if one topping, 10seconds if two toppings, etc.

Characteristic value of BREAKING_SYSTEM is set to ABS ifCAR_ENGINE is set to V6 or V8

Object Dependencies: Dependency Editor

Not ABAP, not a programming language (more like ascript)

Operators: AND, OR, NOT, IF, >, ,

Ar ithmetic expressions:

+ , - , * , /

Standard functions: cos, sin, ceil, floor, etc.

Object variables:

$root: refers to header material in a configuration

$self: refers to the current object

$parent: refers to instance above $self

Note that ABAP function modules can be called independencies as variant functions

Configuration Cockpit

Transaction PMEVC

One of the difficulties in VC, when modeling, was tohave all the information available at your fingertips (i.e.,without having five sessions opened!)

This cockpi t solves that issue: It allows you to navigatethrough all relevant objects (characteristics ,dependencies, )

7 Key Points to Take Home

You now understand the working principles of SAP VC,and you are able to buil d a simple, working model

but you feel that you just touched the tip of theiceberg

SAP VC is a powerful and flexible tool , and can be quitecomplex

SAP VC spans the whole organization (sales,engineering, production , etc.)

73

7 Key Points to Take Home (cont.)

It is obvious that a VC project is not just implementinganother module

There are many ways to make VC work for you, but the

goal is to find the optimalway (functionalities,performance, maintenance, etc.)

You need to learn more in our next session
