If you know what is the maximum/latest date you are looking for, you can use the "Filter rows/cells on date" processor.
However, if you do not know what is the value of the max on that colum, then the prepare recipe is not the best option. This is because (most of) its processors operate on a row by row basis. The kind of aggregation needed to calculate a max, min, avg, etc is not available for this recipe unless the values are contained in the same row.
Hope this helps.
