In order to adjust stocks that are shown less but in fact are more, then stock adjustment plus can be used. For the reverse of this operation go to Stock Adjustment Minus screen. As this is a transaction screen, learn about it here.

The store is selected by default but you can change it if needed. Whatever store you select, the item displayed in the grid below belongs only under that store.

In the grid, select the item either through Item Code or Item Name and go to Qty column field and adjust the stock by adding the shortage value. E.g. If the actual stock is 100 but the inventory system is displaying 90, then you must enter 10 in the Qty field. As soon as you have entered the right value, click on the Save button to confirm. This will adjust the stock to your inventory automatically.
