Add an extra column to your data without entering and validating the formulas yourself.
Press "Edit" and choose "Recipes".
Choose the recipe you want to use, read about them here first.
When you have chosen a recipe, ABC Analyzer will ask for permission to access the columns with the necessary data. Do you, for instance, want to calculate the product's age, you need to point towards the data column with "first receipt" or another column that indicates when the product was added to your stock/assortment.
New columns are shown furthest to the right on the data tab and in the menu under "Edit/Columns/Edit columns". If the column on the data tab is not visible to you, right-click on the grid to make it visible.
