Stock Items 
If you want to enter a material that is kept in stock as a component, select this item category.
Before you start
A valid material master record with a material type that supports stock must exist in the plant you select.
Pipeline materials (material type PIPE) are not kept in stock, so you cannot enter them as stock items.
Special functions
The following are examples of functions that are supported for stock items:
- In an alternative item group, you can group together all stock items.
- You can use the discontinuation functions to transfer dependent requirements that are no longer covered by stock to a follow-up item.
Stock items are handled in the following ways in related application areas:
- For example, in MRP, activities are started that ensure that the material is available on a certain date, in sufficient quantity, and at the lowest cost.
- During materials planning, the system creates dependent requirements for all the material components of a product that are subject to material requirements planning (MRP).
- When you open a production order, the system generates a reservation.
- Product costing functions take the material valuation from the material master record (Costing view).
