Let's see an example of buying and selling this item:

• We bought one 70cl bottle of Absolut Vodka.

If we review the stock tracking, we can observe that the consumption generated by this purchase has a variation of +1 unit.

So, once the purchase is complete, we have 1 bottle of 70cl in stock for the central warehouse:

Now we sell it in one of its formats. For example, the shot format which has a measure of 3cl. We create a sales delivery note where we add 10 units of the Absolut Vodka item in the Shot format.

If we review the stock tracking for this item, we can observe the following:

The consumption/stock variation generated by this sale will be -0.43 units. We sell 10 units of the shot format. Each shot is 3cl. Total consumption = 30cl.

The reference format for the item is the 70cl bottle, therefore:

30cl (shot) / 70cl (standard bottle format) = 0.43 70cl bottles It is the stock variation generated by selling 10 units of that format (3cl shot).

If we now check the stock of this item, we can see that it will be 0.57 bottles of 70cl.

1 (initial stock) 70cl bottle - 0.43 (variation due to the sale of 10 shots) = 0.57 70cl bottles

If, on the other hand, we make a sale of 1 shot, we would be generating a consumption of 3cl and the stock variation would be:

3cl / 70cl (reference format) = 0.043 70cl bottles

Another possibility is to sell our own 70cl bottle format; in this case, the stock variation will be -1 = (70cl / 70cl), since we are selling the same unit as the reference format.
