Negative Stocks
„ You can also manage negative stock balances for materials with moving average price control and 
for special stocks, such as vendor consignment, material provided to vendor, sales order stock, and 
project stock. 
„ Negative stock balances are required if, for organizational reasons, goods issues are entered before 
the corresponding goods receipts, and the material is already physically located in the warehouse. 
„ Once you have posted the goods receipts, the book inventory balance should correspond with the 
physical stock again \u2013 in other words, it should no longer be negative. Negative stocks always 
indicate that physical movements have to be entered in the system at a later stage. 
„ If you work with negative stock balances, you have to ensure that you do not have negative stocks on 
the balance sheet key date or when you carry out a physical inventory. 
„ As of Release 4.6A, blocked stock can also be negative.
