Making Settings for Configuration 
Use
Two objects used in assembly processing in the Project System can be configured: the standard network and the material. You can use both a configurable material and a configurable standard network in one assembly order.
To use configuration, you assign a configuration profile to the configurable object. This profile contains details about the class to be used.
For information about variant configuration in the R/3 System, refer to the R/3 Library for Variant Configuration in Logistics - General (LO-VC).
Prerequisites
If you want to use configuration, you have to have previously created the characteristics that you want to use in the variant class. For more information, refer to
Maintaining Characteristics and Classes for Config. If both the material and the standard network are configurable, they should be assigned to the same class. If the standard network has not been assigned to a class (it does not have a configuration profile), then the configuration from the material is used. This is also the case, if the class for the standard network is part of the class for the material. Otherwise the characteristic values are assigned separately when the network is created.
To use configuration with a material, you have to have set the Material is configurable indicator on the Basic data view (in the standard system) of the material master.
Procedure
Creating Classes

The class system is also used for other purposes in R/3. In such cases other class types are used. For instance, class types 013 and 014 are used for summarization in the Project System.
Creating Configuration Profiles for Materials and Standard Networks
The procedure for creating a configuration profile for standard networks and materials is basically the same.
For Materials
For Standard Networks
In both cases the Select Configurable Object dialog box appears. Make sure that the correct object has been selected, change if necessary.

If instead of the dialog box the initial screen for the incorrect object appears (for example, if you want to create a configuration profile for a material and the initial screen for standard networks appears), choose Extras ® Change configurable object. The Select Configurable Object dialog box appears.
Continue for both objects as follows:
