Stock Determination 
Use
In backflushing, you can control from which stocks the components are to be withdrawn. For example, you may want to withdraw stock from unrestricted-use stock first and then from consignment stock or vice versa. Using the stock determination functions, you can define strategies which the system then uses to automatically determine which stock type is to be used for the withdrawal.
Integration
Stock determination is integrated with the following components:
Inventory Management, Sales, Warehouse Management, Repetitive Manufacturing, Production Orders and the Pull List.
Prerequisites
You must define the stock determination strategy and the necessary parameters in Customizing for Stock Determination.
You must assign a stock determination rule in the repetitive manufacturing profile of the assembly.
You must assign the stock determination group to the component in the material master record.
The combination of stock determination rule and group determines the strategy.
Features
The system uses the predefined stock determination strategy to check which stock is to be withdrawn.
You can define stock determination for the following stocks:
Unrestricted-use stock
Vendor consignment stock
Pipeline material
The system usually determines the storage location for component withdrawal via a storage location determination in the BOM explosion. If, however, you want to determine the storage location dynamically according to certain criteria, you can also use dynamic storage location determination tools in the Stock Determination component.
Note
Requirements with no predefined storage location cannot be processed in the pull list.
If several consignment stocks from different vendors exist when backflushing, you can use stock determination to instruct the system to choose the vendor with the cheapest prices and who has enough stock available, for example.
Note
The appropriate Purchasing Information Records must be available for withdrawing pipeline material or vendor consignment material.
