The scenario for sales order production is mapped mainly by means of the requirements class. The system can derive the requirements type in two ways on the basis of the Check control of requirements type Determination table.
Requirements Type Data
The system derives the requirements type data from the material master data in the following ways:
It attempts to find the requirements type using the strategy group in the material master, with the requirements class determination method.
It determines the requirements type using the MRP group, if the strategy group has not been maintained.
It uses the material type to access the relevant control tables if the MRP group has not been defined.
Requirements Class Determination

The system can derive the requirements type from a combination of data, namely the material master record and the sales document.
Types
The various derived requirements types are as follows:
- The system attempts to derive the requirements type from the Material Requirements Planning (MRP) type using the material master record and the item category in the sales document. If the system finds no requirements type here, it attempts to find a requirements type with the item category and the MRP area type.
- If this is not possible, the system searches for a requirements type with the item category only.
If this last attempt fails, the system declares the transaction as irrelevant for the availability check or transfer of requirements.
Customizing – Requirements Class (1)

To be able to collect costs on a sales order item, you must select a requirements class that specifies an appropriate account assignment category. Collecting costs and revenues for sales order items is recommended in complex MTO production. In the standard system, the corresponding account assignment category is E.
