Special Settings for Production Orders 
All Customizing settings that you require for assembly processing with production orders, such as strategy group, requirements class and order type are already predefined by SAP in the Standard System.
Strategy Groups
The following strategy group is predefined for production orders:
- Strategy group 82: assembly processing with production orders
Here, the static procedure (that is, the 1:1 link between production order and sales order) is preset as the assembly type.
Requirements Type and Requirements Class
Strategy group 82 refers to the following requirements type or requirements class in the Standard System.
- requirements type KMFA
- requirements class 201
Order Type
The following order type for production orders is predefined in the requirements type 201:
- Order type PP04: Production order with assembly processing
If, for some reason, you want to use an order type that is different to the one predefined by SAP, you must make sure that the following scheduling parameters are set for the order type:
- Key ‘Backward scheduling’’
- Indicator ‘Adjust basic dates’’
If you use all the standard system settings, you do not need to make any additional settings in Customizing:
Bills of Material
For assembly processing with production orders, the finished product must have a valid bill of material.
