Posting Changes in a Decentralized Warehouse 
Purpose
A posting change generally refers to a bookkeeping change - a change in information - about a particular material. For most posting changes, such as changing a batch number or releasing blocked stock, the goods themselves remain in the same physical location.
You process posting changes in Inventory Management (IM) and Warehouse Management (WM) to change the status of a material in the warehouse.
You cannot carry out certain posting changes, for example, if the vendor data is not known. For example, you can convert materials from consignment stock to unrestricted-use stock, but not from own stock to consignment stock.
