After installation, you can configure different features. For that we have added section Barcode, in inventory configuration.

If you want to prevent to add different product than order than just go to Inventory >> Configuration >> Settings, in that you will see one section called Barcode. In barcode section you will option Prevention to add different product than order to prevent other products. In that you can set operation types. While scanning item, if other item is scanned and the transfer order's operation type is set in configuration section than it will give error message

As you can see in screenshot, first we have defined two operation types (YourCompany: Delivery Orders, YourCompany: Receipts) to prevent other items to be add. Now there is a transfer order with two products (Bolt, Screw).

Now if i scan order product than it will raise warning that "You are not allowed to add different product than order". But you can add different product in other transfer order of other operation type which are not set in configuration.

If you want to fill done quantity automatically on scanning, then go to Inventory >> Configuration >> Settings, in that you will see one option Auto Fill Product Quantity on barcode scan

As you can see in above screenshot that, there are two operation types selected to auto fill quantity. So we will test with transfer order created above.

On scanning any barcode it will open popup wizard to allows you to select number of packages/product to be auto fill.

If the transfer order is backorder than it will specify that the actual order quantity and remaining quanity to validate. You can see in screenshot

If you want to skip source location scanning than just go to Inventory >> Configuration >> Settings, in that you will see one option Skip Source Location Scanning For Packages

You can see in screenshot that you can directly scan product, no need to scan source location. It is very useful when the transfer order is package and that package contains number of products.

If you want to skip destination location scanning than just go to Inventory >> Configuration >> Settings, in that you will see one option Skip Destination Location Scanning For Packages, when scan completes it will automatic skip destination location.
