Special Settings for Projects 
SAP has predefined all the settings in Customizing you need to use networks in assembly processing: strategy group, requirements class, network type and condition type. If you use the standard settings, you do not have to make any additional settings in Customizing. However, you will have to make settings for your materials and standard networks.
Strategy Groups
SAP has predefined the following strategy groups for networks and projects:
- 83: Assembly processing with networks with requirements class 202
- 85: Assembly processing with network/project with requirements class 212
If you do not assign an appropriate MRP controller or strategy group to your material, you will not be able to create a network from a sales order.

For more information on strategy groups, refer to the section entitled
Requirements Classes
SAP has predefined the following requirements class for networks:
- 202: A network with network type PS05 (header account assignment) and account assignment category E (assignment to the sales order).
- 212: A network with network type PS04 (activity account assignment) and account assignment category D (assignment to project or WBS element).

For more information on requirements classes, refer to implementation guide Production under Requirement types/requirement classes.
Network Types
SAP has predefined the following network types:
- PS04 and PS05: Networks with scheduling type backwards, where the scheduled dates are calculated automatically and the basic dates are adjusted automatically. When you set the indicator for the basic dates, the system updates the network basic dates with the scheduled dates and then writes them into the sales order as confirmed dates.
If you want to use a different network type than the ones which SAP has predefined for you, you have to set the indicators for the scheduling parameters: key and Indicator: adjust basic dates.

Prerequisites for Networks
To be able create a network from a sales order you need:
A Material Master Record
The data in the material master for the product controls whether a network is created. The strategy group in the material master controls whether a network can be created from a sales order. The requirements class assigned to the strategy contains all the important information for this, such as assembly type, network type, configuration, account assignment category.

For more information on creating a material in the material master, refer to the SAP documentation LO - Managing Material Master Data
A Standard Network for Production or Assembly
The network that is created in the background from a sales order is always copied from the standard network to which the material in the sales order is allocated. You can also assign the standard network to a standard WBS element so that the sales order can be settled to a project, for example.

Network Settings
In the standard network, you can make the link between the material, the network to be created for assembly processing, and the account assignment. Every time you create a sales order for the material you entered here, the system will automatically copy this standard network to create the network. If you do not enter any data here, you must enter the required data online every time you create a sales order for assembly processing.
You make the settings from the Basic data menu, by selecting the menu options Standard structures → Alloc mat → std.ntwk.
The Network Parameters - From Sales Order screen is displayed.
On the detail screen you allocate a material to a standard network as well as to a standard WBS element for account assignment.
