To find out which year had the highest percentage of sales for a product, what method should you use with a pivot table?

To determine which year had the highest percentage of sales for a product using a pivot table, applying the method of setting the value to show as a percentage of the row total is the most effective approach. This allows you to visualize sales contributions relative to the total sales for each year effectively.

By selecting "Show Values As > % of Row Total," the pivot table computes the percentage contribution of each year's sales in relation to the overall total. This presentation clearly highlights which year performed best in terms of its share of total sales, making comparisons straightforward.

Using this method is advantageous since it directly relates each year's sales to the overall picture, enabling quick identification of the highest-performing year. This contrasts with calculating averages, which may obscure individual performance, or sorting by sales volume, which doesn’t provide a comparative perspective against total sales. Conditional formatting may enhance visibility but does not specifically calculate percentages, making it less suitable for this analysis.
