When your inventory arrives, you can use a transfer to make sure that you receive everything that you're expecting. Receiving inventory means that the item has arrived, you have evaluated that item, and decided to accept or reject it.
When you accept an item in your transfer, the available quantity is added on yourInventorypage. When you reject an item in your transfer, for example if it was damaged, it does not adjust your inventory quantity.
If you're receiving extra items from the origin location that were not accounted for in the transfer, then you can specify a greater number of items in theAcceptcolumn.
