In WM, it is important to know what quantity of a stock is in a particular storage bin, but also its status and whether or not it is available. Stock in the warehouse is categorized in WM as follows:

1. Available Stock

Unrestricted-use stock that is physically located in the warehouse, valuated, and not subject to any kind of usage restrictions. User can carry out all stock movements for this stock to include stock transfers, put away and picking.

2. Inspection Stock

The Quality Management inspection data in the QM view of the material master determines whether a percentage of stock is to be designated as inspection stock when it is received in the warehouse. Once this stock has been inspected and a usage decision has been made, User carry out a transfer posting in the Inventory Management component and subsequent Posting Change in WM to remove the category Q, thus converting it to available stock.
