inventory movement

it would be great if the Inventory system had a Stock Card screen showing all Sales /consumption and all purchases(received).. I know there is something similar in the system but it doesn't link the sales/consumption to the POS transaction and the purchases(received) are not linked to the purchase invoice... below is an example of our current system

this screen really helps is identify transactions that may have been sold for less than cost as well as showing us each movement transaction for an Inventory item and links to the transaction so we can see more details
