4. Characteristics:
· To define the features of the configurable Material
· Assignment of object dependencies to characteristics and characteristics value to ensure complete & consistent configuration
· Characteristics values can be restricted during configuration using restrictable characteristics.

5. Classification:
· To hold the characteristics of the configurable material
· Class used should support variant configuration
· SAP Standard class for variant configuration is 300
· Can be used for classifying materials
· Class hierarchy can be set up for these classes
· Can be used to find objects
· All objects linked to configurable material are classified
· Classes can be used as BOM components
· After configuration the class item is replaced by specific component
· Only Documents and Materials can be used as class components in the BOM
· Configurable Material is assigned to Class 300

6. Configuration Profile:
· To define central settings for configuring the object
· Configurable object can have more than one profile
· Allows to assign the configurable object to variant class
· Define settings that affect the display of characteristics in value assignment screen
· To assign object Dependencies to the configurable material viz Dependency net, procedures and actions
· To maintain configuration parameters for BOM explosion
Creating Configuration Profile:
Logistics---Central Functions ---Variant configuration---Configuration Profile---Create (T. Code- CU41).

7. Object Dependencies:
Purpose:
· To describe the interdependencies between characteristics and characteristic values
· Component and Operation selection
· To change the values of fields for BOM components and Operations
Integration:
· Classification System
· Variant Configuration
Creating Global Dependencies:
Logistics---Central Functions ---Variant configuration---Dependency---Single Dependency---Create (T. Code - CU01).

Dependency Types:
Administrative Types:
· Global dependencies are created centrally and can be assigned to several objects. External number/name assignment for the Global Dep
· Local dependencies are created for one object and can be used with that object only. Internal Number assignment for local Dependency
Technical Types:
· Preconditions
· Selection Conditions
· Actions
· Procedures
· Constraints
Preconditions:
· To hide characteristics and characteristic values which are not allowed while configuration.
· Allocated to characteristic or characteristic value that we want to hide
· Precondition is fulfilled if the condition entered is fulfilled or not violated.
· A Precondition is fulfilled, if the specified value is selected for the specified characteristic or no value is selected for the specified characteristics
· A Precondition is not fulfilled if a different value is selected for the specified characteristics
Selection Conditions:
· To determine which variants require a specific component or operation
· To determine when it is mandatory to assign a value to a characteristic
· We can allocate the selection condition to the following objects
Characteristics
BOM components
Operations
Suboperations
Sequences of operations
Production Resources/Tools (PRTs)
· Selection condition is fulfilled if the value in the condition is set for the characteristic
· Selection condition is not fulfilled if a different value is set or no value is set
Procedures:
· To infer values for characteristics
· Can be assigned to the following objects
Characteristic that triggers procedure
Characteristic value that triggers procedure
Configuration Profile
BOM components
Operations in the task lists
· Uses the variable $SELF before characteristic
· Procedures are always used for variant pricing
· Procedures can overwrite values set by other procedures
· Various Key words(variables) used in procedures
$SET_DEFAULT
$DEL_DEFAULT
$SUM_PARTS
$COUNT_PARTS
$SET_PRICING_FACTOR

· Processing sequence can be defined in case of multiple procedures assigned to an object

Constraints:
· Mainly used for intensively interactive configuration
· The main purpose of a constraint is to monitor the consistency of a configuration
· Can be used to describe the dependencies between completely different objects and their characteristics
· Constraints are not directly allocated to individual objects
· Constraints are grouped together to form dependency nets and allocated to configuration profile
· Object variables $SELF, $ROOT,$PARENT are not used
· Refer to objects by entering the class to which the objects are allocated
· Constraints are declarative dependencies, the processing sequence and the point in time when constraints are processed are not relevant
· Constraints are not processed in a specific order, we cannot determine when a specific constraint is used
· In any processing situation a constraint is processed only once , if a value that is relevant to the constraints is changed, the constraint is triggered again
Structure of Constraints:
· Four sections in a constraint,each part is identified by a key word, key word is followed by a colon, each section ends with a period
· Four Sections
OBJECTS: must
CONDITION: optional, if entered must be fulfilled
RESTRICTIONS: must, relation between objects and characteristics
INFERENCES: enter characteristics for which values are to be inferred
Actions:
· To infer values for characteristics, cannot overwrite values that are set by an action
· To change field values in BOM items or operations in routings
· We can assign actions to the following objects
Characteristic value that triggers action
Characteristic that triggers action
BOM items –viz for changing the quantity
Configuration profile
Operations in task list – viz to change the
Standard values
· Enter the variable $SELF before the characteristic
· Cannot use the following expressions

8. Configuration Simulation:
· To check the authenticity configuration Model created before actual process
· To test whether we have created objects correctly and whether dependencies work
· BOM for this simulation is selected according to the BOM application in the configuration profile
· Can use configuration simulation only for materials
