Key insights RANKX is a DAX function in Power BI and Excel used to rank items in a table based on values in a specific column. The RANKX function compares each row’s value to others and assigns a ranking number, with 1 being the highest or lowest depending on settings. You can customize the ranking order by choosing ascending or descending when using RANKX. Ties (when two or more values are the same) are handled by assigning the same rank and skipping numbers for the next ranks. The function can use filters, letting you rank only selected groups or categories within your data. RANKX helps visualize performance, such as showing top-performing products or employees based on sales or other metrics.
