To reduce the quantity found of a certain product, simply return to the Reporting Screen and minus the difference from the original amount.
In this example, the user originally found 540 base units of Tomato Sauce 300ml. They now need to correct the amount to make it a total of 450 base units. Therefore, they subtract the difference (90 base units) from the original by entering '-90' into the 'Base Unit/Each Found' category and then pressing 'Save and Close'.
