To take a cycle count of your stock, you first have to make a cycle count template and add your ingredients and recipes to it. To learn how to do that, check out this article (How do I create a cycle count template).
From the "Cycle Counts" page, click the "+" to create a new cycle count. Select the location you would like to take the cycle count for and the cycle count template that you would like to use. Once these are selected, click "Create."
You may now take a cycle count using your new template! Click "Submit" to finalize the cycle count quantities.
